Description of Revision (list changed pages when all pages of original analysis were not changed): "

This calculation evaluates the Joss of voltage (LOV) relay setpolnt during a sustained degraded voltage event.

The normal (non-accident) time delay associated with Iha second-level undeivoltage relays (degraded voltage relays) could allow the voltage at the 4.16 kV buses to remain at low levels for an extended period of time (332.3 seconds) before transfer of all safety-related loads to the emergency diesel generators. This calculation

evaluates the LOV relay setpoint to ensure that the safety-related motors that may be running during normal conditions will continue to operate during a sustained degraded voltage event.

6 Are assumptions compatible with the way the plant is operated and with the licensing basis?

Do all unverified assumptions have a tracking and closure mechanism in place?

Do the design inputs have sufficient rationale?

Are design inputs correct and reasonable with critical parameters identified, if a ro riate?

Are design inputs compatible with the way the plant is operated and with the licensin basis?

Instructions aod Guidance All Assumptions should be stated in clear terms with enough justification to confirm that the assumption is conservative.

For example, 1) the exact value of a particular parameter may not be known or that parameter may be known to vary over the range of conditions covered by the Calculation. It is appropriate to represent or bound the parameter with an assumed value. 2) The predicted performance of a specific piece of equipment in lieu of actual test data. It is appropriate to use the documented opinion/position of a recognized expert on that equipment to represent predicted equipment performance.

Consideration should also be given as to any qualification testing that may be needed to validate the Assumptions. Ask yourself, would you provide more justification if you were performing this analysis? If yes, the rationale is likely incom lete.

Ensure the documentation for source and rationale for the assumption supports the way the plant is currently or will be operated post change and they are not in conflict with any design parameters. If the Analysis purpose is to establish a new licensing basis, this question can be answered yes, if the assum tion su arts that new basis.

If there are unverified assumptions without a tracking mechanism indicated, then create the tracking item either through an ATI or a work order attached to the implementing WO. Due dates for these actions need to support verification prior to the analysis becoming operational or the resultant lant chan e bein o authorized.

The origin of the input, or the source should be identified and be readily retrievable within Exelon's documentation system.

If not, then the source should be attached to the analysis. Ask yourself, would you provide more justification if you were performing this analysis? If yes, the rationale is likely incom lete.

The expectation is that an Exelon Engineer should be able to clearly understand which input parameters are critical to the outcome of the analysis. That is, what is the impact of a change in the parameter to the results of the analysis? If the im act is lar e, then that arameter is critical.

Ensure the documentation for source and rationale for the inputs supports the way the plant is currently or will be operated post change and they are not in cont lict with any design parameters.

Are Engineering Judgments compatible with the way the plant is operated and with the licensing basis?

Do the results and conclusions satisfy the purpose and objective of the Desi n Anal sis?

Are the results and conclusions compatible with the way the plant is operated and with the licensin basis?

Have any limitations on the use of the results been identified and transmitted to the appropriate or anizations?

Have margin impacts been identified and documented appropriately for any negative impacts (Reference ER-AA-2007?

Does the Design Analysis include the applicable design basis documentation?

Have all affected design analyses been documented on the Affected Documents List (AOL) for the associated Conti uration Chan e?

Do the sources of inputs and analysis methodology used meet committed technical and regulatory re uirements?

Instructions and Guidance See Section 2.13 in CC-AA-309 for the attributes that are sufficient to justify Engineering Judgment. Ask yourself, would you provide more justification if you were performing this anal sis? If es, the rationale is likel incom lete.

Ensure the justification for the engineering judgment supports the way the plant is currently or will be operated post change and is not in conflict with any design parameters. If the Analysis purpose is to establish a new licensing basis, then this question can be answered yes, if the 'ud ment su orts that new basis.

Why was the analysis being performed? Does the stated purpose match the expectation from Exelon on the proposed application of the results? If yes, then the analysis meets the needs of the contract.

Make sure that the results support the UFSAR defined system design and operating conditions, or they support a proposed change to those conditions. If the analysis supports a change, are all of the other changing documents included on the cover sheet as im acted documents?

Does the analysis support a temporary condition or procedure change? Make sure that any other documents needing to be updated are included and clearly delineated in the design analysis. Make sure that the cover sheet includes the other documents where the results of this anal sis rovide the in ut.

Make sure that the impacts to margin are clearly shown within the body of the analysis. If the analysis results in reduced margins ensure that this has been appropriately dispositioned in the EC being used to issue the analysis.

Are there sufficient documents included to support the sources of input, and other reference material that is not readily retrievable in Exelon controlled Documents?

Determine if sufficient searches have been performed to identify any related analyses that need to be revised along with the base analysis. It may be necessary to perform some basic searches to validate this.

Compare any referenced codes and standards to the current design basis and ensure that any differences are reconciled.

If the input sources or analysis methodology are based on an out-of-date methodology or code, additional reconciliation may be required if the site has since committed to a more recent code Yes/ No IN/A

I Analysis No. QDC-6700-E-2173 Revision 000 PAGE 3of18 I 1.0 PURPOSE The purpose of this calculation is to evaluate the loss of voltage (LOV) relay setpoint during a sustained degraded voltage event. The normal (non-accident) time delay associated with the second-level undervoltage relays (degraded voltage relays) could allow the voltage at the 4.16 kV buses to remain at low levels for an extended period of time. This low level of voltage could last as long as 332.3 (324+8.3) seconds (Ref. 4.2.1) before transfer of all safety-related loads to the emergency diesel generators. This calculation evaluates the LOV relay setpoint to ensure that the safety-related motors that may be running during normal conditions will continue to operate during the 332.3 second time delay without stalling or being damaged. This calculation will determine new analytical limits for the LOV relay.

Basis: The existing ETAP model (Input 2.5) shows RHRS Emergency AHU 1A operating at rated horsepower (100% loading). The actual load on the RHRS Emergency AHU 1A motor was measured at 6.21 HP per WO 0478721 (Ref. 4.3.2), which is less than 84% of the motor rated 7.5 HP. Additionally, the remaining RHRS Emergency AHU's (18, 2A, and

28) are modeled in the existing ETAP model at 84% of rated horsepower.

All four RHRS Emergency AHU motors have similar fan loads and therefore the loading for RHRS Emergency AHU 1A can be modeled in ETAP at 84% of rated horsepower.

3.2.2 It is assumed that Core Spray Emergency AHU 1 B can be modeled as operating at 88% of rated motor horsepower.

Basis: The existing ETAP model (Input 2.5) shows CS Emergency AHU 18 operating at rated horsepower (100% loading). Current readings were taken on CS Emergency AHU 18 per WO 01388989 (Ref. 4.3.3) and the highest measured phase current was 4.8 A, which is 74% of the 6.5 A motor rated current. Conservatively assuming a maximum 110% motor voltage with the measured value of current results in less than 88%

loading (1.1x0.74=81.4%). Additionally, the remaining CS Emergency AHU's (1A, 2A, and 28) are modeled in the existing ETAP model at 88%

of rated horsepower. All four CS Emergency AHU motors have similar fan loads and therefore the loading for CS Emergency AHU 1 B can be modeled in ETAP at 88% of rated horsepower.

3.3 Engineering Judgments 3.3.1 The results of the transient EOG voltage dip analyses from diesel loading calculations 9390-02-19-1, 9390-02-19-2, and 9390-02-19-3 are used in this calculation. The Unit 1, Unit 2, and 1/2 diesel loading calculations are not maintained and have been superseded by ETAP calculation QOC-6700-E-1503; however, the ETAP calculation only calculates the steady state EOG loading and does not carry forward the transient EOG voltage dip analyses. The calculated worst case EOG voltage dips were based on the starting of large motors during both LOOP/LOCA and LOOP without LOCA and based on the running load at the time of the motor starts. The results of the transient voltage dip analyses from the diesel loading calculations are used in this calculation as the loading on the EOGs and the sequence of automatic large motor starts seldom change.

Furthermore, an exact value for the transient voltage dip is not needed as

03.7.696-7.00. (See last page of Attachment A for ETAP Audit Trail Information) 6.0 METHOD OF ANALYSIS This analysis will evaluate the safety-related motors that may be running during normal conditions during a severely degraded voltage condition that lasts for an extended period of time. The maximum normal (non-LOCA) degraded voltage time delay is 324 seconds for the DVR timer following the 8.3 seconds DVR time delay (Ref. 4.2.1 ). Therefore, the 4.16 kV bus voltage may drop below the DVR minimum allowable value but remain above the loss of voltage relay setpoint for as long as 332.3 (8.3+324) seconds. This analysis ensures that the safety-related motors that may be running during an extended degraded voltage event do not stall or trip due to thermal overload relay operation. The motor control circuits are evaluated. Finally the LOV relay settings are evaluated to ensure that

the relays due not spuriously operate during expected voltage transients.

6.1 Motor Stall Voltage Calculation The torque developed by a motor is proportional to the square of the voltage (Ref.

4.5.1 ). Based on this relation, Equation 1 is derived and used to determine the minimum motor voltage to preclude motor stalling:

Tbreakdown =

The existing LOV relay setpoint was chosen such that it is bounded by the analytical limits plus the total error (Ref. 4.1.1 ). For the purpose of the motor stalling evaluation, this calculation will also consider time-voltage characteristics of the relay. The LOV relay operating time is not defined at the nominal setpoint.

Therefore, for a given setting, the time-voltage curves are used in order to determine a dropout voltage with a defined operating time.

l Analysis No. QDC-6700-E-2173 Revision 000 PAGE 9of18 l The station ETAP model (Input 2.5) is used to determine the downstream motor terminal voltages (for the motors identified in Input 2.3) with the 4.16 kV ESS buses fixed at the LOV relay setpoint (including the total error and time-voltage characteristics). The ETAP model (Input 2.5) is evaluated with the 4.16 kV ESS Buses (13-1, 14-1, 23-1, and 24-1) fixed at the LOV relay setpoint (including the total error and time-voltage characteristics). An infinite bus is connected to each of the four 4.16 kV ESS Buses in order to model a specific operating voltage. For each of the safety-related motors that may be running during normal conditions, a fictitious bus is added between the motor and its equipment cable in ETAP. These fictitious buses are needed to represent the motor terminals so that the motor terminal voltages appear in the ETAP load flow output reports. The fictitious buses are named using the motor load name with "-T" added to the end. The Unit 1 motor terminal voltages are evaluated using Scenario 1M1 SPLITL TCM, and the Unit 2 motor terminal voltages were evaluated using Scenario 2M1 SPLITL TCM from the ETAP calculation (Ref. 4.1.2). These scenarios model the normal Unit 1 and Unit 2 loading during Mode 1, split bus operation. The scenarios are modified by opening breakers to isolate the non-safety related buses such that only the 4.16 kV ESS busses and connected downstream buses are energized. The motor terminal voltages are compared to the minimum voltages required to preclude motor stalling for acceptability.

6.3 Motor Protective Device Evaluation The thermal overload (TOL) relays for the safety-related 480 V MCC motors that may be running during normal conditions are evaluated. The motors are protected by CR124 thermal overload (TOL) relays with non-ambient compensated CR123 TOL heaters. There are no normally running, safety-related 480 V switchgear motors or 4.16 kV switchgear motors. Calculation QDC-7800-E-0612, Rev. 002 (Ref. 4.1.6) selects the thermal overload heaters for the Reactor Building continuous duty motors required for operation during a LOCA. In order to ensure that safety-related loads are available, this calculation further evaluates the existing 460 V motor TOLs to ensure that they will not trip during a sustained low degraded voltage condition, which would prevent the loads from performing their intended safety functions.

The TOL trip curves are compared to the running motor currents (at tow voltage) to ensure that no TOL relays will trip on overload in less than 332.3 seconds, which is the maximum DVR time delay (Input 2.6). The TOL relay tripping characteristics are shown on GE Drawing 231HA165 (Ref. 4.4.4). On this drawing,

. the trip curves do not extend to less than 150% of the ultimate trip current for the heater, and therefore tripping times for slight overload conditions cannot be determined. by reading the curves directly. Per NES-EIC-10.02, Rev. 000 (Ref.

4.3.5) and NES-EIC-10.03, Rev. 000 (Ref. 4.3.6), a thermal overload relay operates as a constant 12T device. Therefore, the thermal energy developed during a degraded voltage condition, in terms of t2T, is compared to the 12T of the TOL relay. The TOLs are adequately sized if the following condition is met, shown in Equation 2:

For low levels of motor overload current that persist for an extended period of time, as is the case during a sustained degraded voltage condition, some of the heat generated in the TOL heater will have time to dissipate to the environment.

As a result, the actual tripping time of a thermal overload relay, at these low levels of overload current, will be longer than what is determined by using the constant 12T value. This adds further conservatism to the results.

The TOL heater 12T values are determined using the methodology in NES-EIC-10.02, Rev. 000 (Ref. 4.3.5). Data points are read from the minimum trip curves, for each tripping zone, to calculate the 12T value of each TOL. There are slight variations in the values calculated for each data point due to inaccuracies in reading the curve and therefore the lowest calculated 12T value is used for conservatism. The TOL relay tripping curves and tripping zones for each TOL heater are shown on GE Drawing 231 HA165, Sheets 2 and 3 (Ref. 4.4.4) and the ultimate trip currents (UTC) are obtained from Calculation QDC-7800-E-0612, Rev. 002 (Ref. 4.1.6). The 12T value for each data point for each TOL heater is calculated using the following equation.

(/ 2Thoi = (lp.u. x UTC) 2 x Time Equation 3 The motor running currents at degraded voltage are calculated by considering the motors as constant kVA devices. As voltage decreases, the current will increase proportionately. Since the product of the motor power factor and efficiency can be closely approximated as a constant value, the motor current will vary in proportion to the loading. Therefore, the motor current is multiplied by the ratio of brake horsepower to rated horsepower. The motor current at degraded voltage is calculated using the following equation.

6.4 Motor Control Circuit Evaluation The motor control circuits for the safety-related 480 V MCC motors that may be running during normal conditions are evaluated to ensure that reduced voltages would not cause the motors to drop out due to contactors dropping out or due to blown control circuit fuses.

I Analysis No. QDC-6700-E-2173 Revision 000 PAGE 11of18 I 6.5 Transient Voltage Dip Evaluation As described in Section 6.2, new LOV relay settings may be required to ensure that safety-related motors have adequate voltage during a severe degraded voltage condition. The voltage transient during a LOCA block start for Unit 1 and Unit 2 is evaluated to ensure the LOV relays due not spuriously actuate. Since the LOV relays are active when the 4.16 kV ESS buses are aligned to the emergency diesel generators (EOGs), the relays must not drop out for any expected EOG voltage transient. Therefore, the voltage transients due to large motor starts during a Loss of Offsite Power (LOOP) both with and without a Loss of Cooling Accident (LOCA) event are evaluated.

6.6 Coordination with Protective Devices The timing characteristics of the LOV relays (Ref. 4.4.2) are compared to the timing characteristics of the 4.16 kV ESS bus overcurrent protective relays (Refs.

4.4. 5-4.4. 7). Specifically, the fault clearing times of the protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 VESS transformers are evaluated to ensure that a fault will be cleared before the LOV relays dropout on low voltage.

6. 7 Determination of Analytical Limits The existing LOV relay analytical limits are based on the existing nominal setpoint with a plus or minus 5% tolerance. The LOV relay voltage new analytical limits will be based on the nominal setpoint evaluated in this calculation, plus or minus 5%.

7.0 ACCEPTANCE CRITERIA 7.1 The setpoint for the loss of voltage relays must be high enough to prevent the stalling and tripping (due to thermal overload relay operation) of the safety-related motors that may be running during normal conditions and low enough to prevent spurious operation due to expected voltage transients.

8.0 CALCULATIONS AND RESULTS 8.1 Motor Stall Voltage Calculation The minimum motor terminal voltage to preclude motor stalling is calculated using Equation 1 from Section 6.1 and using the motor data from Input 2.4. Since the motor BHP is proportional to the torque, the BHP (in percent of rated HP) will be used for the load torque (in percent of full load torque).

In order to take into account the timing characteristics of the relay, the vendor time voltage characteristic curves are used for the motor evaluation. The existing GE IAV69 LOV relay nominal setpoint is 90% of the 93V tap (Input. 2.1 ). Based on the IAV69 relay time-voltage curves in the vendor manual (Ref. 4.4.2), the relay operating time is not defined at the nominal setpoint. The time-voltage curves show that the 90% time-voltage curve is defined for voltages between 0% (at 2.1 seconds) of tap value and 86% (at 11 seconds) of tap value (Ref. 4.4.2). The highest defined point on the curve (86% at 11 seconds) is used in order to have a defined operating time associated with the relay operation. The total negative error for the LOV relay is 2.25Vand the PT ratio is 35:1(Input2.1). Therefore, the 4.16 kV ESS bus voltage used in ETAP for the motor evaluation is calculated as follows:

V@ns = ((OViap

86%)- Error] X PT Ratio V@us = [(93V x 86%) - 2.25V] x 35 = 2720V (Note that the value above is conservatively rounded down to the nearest volt.)

The ETAP model (Input 2.5) is evaluated with the 4.16 kV ESS Buses (13-1, 14-1, 23-1, and 24-1) fixed at a voltage of 2720 V. The ETAP Load Flow Output Reports are included in Attachment A. A review of the motor voltages in the load flow reports shows that the motors have either marginal voltage or insufficient voltage to preclude stalling with the 4.16 kV ESS at 2720V. The results are shown in the following table on the next page.

Per the IAV69 relay vendor manual {Ref. 4.4.2} the next available setting, utilizing the same 93V tap, is 95% of 93V (93V*95% = 88.35V setpoint}. The 95% time-voltage curve is defined for voltages between 0% {at 1.1 seconds} of tap value and 90% (at 7 seconds) of tap value. The highest defined point on the curve {90% at 7 seconds) is used for the evaluation. The total negative error for the LOV relay is 2.25V and the PT ratio is 35:1 (Input 2.1 }.

Therefore, the 4.1'6 kV ESS bus voltage used in ETAP for the motor evaluation is calculated as follows:

Per Input 2.6, the maximum normal (non-LOCA) degraded voltage time delay is 8.3 seconds for the DVR time delay plus 324 seconds for the external DVR timer, for a total time of 332.3 seconds. Therefore, the TOL trip curves are compared to the running motor currents {with the 4.16 kV ESS buses operating at 2850V) to ensure that no TOL relays will trip on overload in less than 332.3 seconds, which is the maximum DVR time delay.

11.141 14 The above table shows that the motor TOL relays will not trip before the DVRs dropout.

During a loss of voltage event that does cause the LOV relays to dropout, the running motors may briefly stall before the degraded voltage source is disconnected from the buses. The time delay associated with the LOV relay is dependent on the level of undervoltage. It was shown above that no motors will stall and that the TOLs will not trip when the 4. 16kV ESS buses were at voltages above 2850V. The time-voltage curve of the LOV relay was evaluated in Section 8.2 and a voltage of 2850 V was derived in order to evaluate a voltage that had a defined relay operating time associated with it. The value of 2850V corresponded to relay operating time of approximately 7 seconds. In order to provide margin for any timing tolerances, which are not published by the vendor, a time of 1 O seconds is assumed where the motors may stall before the LOV relays dropout.

The motors would be available to restart once the buses were repowered by the EDGs as long as no TOL relays tripped on overcurrent. Therefore, the TOL trip curves are compared to the motor locked-rotor current to ensure that no TOL relays will trip in less than 10 seconds. This is conservative because the motor current during a stall at reduced voltages will be lower than locked-rotor current at rated voltage. Based on GE Drawing 231 HA165, Sheet 2 (Ref. 4.4.4), the minimum trip current for Zone B TOL heaters, at 1 O seconds, is 635% of the ultimate trip current. The minimum trip current for Zone C TOL heaters, at 10 seconds, is 785% of the ultimate trip current. The TOL heaters are evaluated in

8.4 Motor Control Circuit Evaluation The motor control circuits, for the safety-related 480 V MCC motors that may be running during normal conditions, are powered from control power transformers (CPTs) off the MCCs. Therefore, the degraded voltage at each MCC will result in a corresponding reduction in control power voltage. For the GE 100 line starters (Size 1) used in the MCCs for the motors being evaluated, the pick-up voltage is 85% and drop out is 63% of the 11 SV coil rated voltage (Refs. 4.1. 7-4.1.9). The turns-ratio of the control power transformer in each circuit is approximately 3.8.

The affected motors are fed from MCCs 18-1A, 19-1, 28-1A and 29-1. As seen from the ETAP analysis (see Attachment A), the lowest voltage at MCCs 18-1A, 19-1, 28-1A and 29-1 is 280 V. Neglecting the voltage drop through the CPT and control cables, the minimum required MCC voltage to prevent contactor dropout would be approximately 276 V (63% x 115V x 3.8 = 276V). This leaves I 1 V1t1cc-Vmin 280V-276V f

. fo approximate y V (

. =

Since the power requirement of the contactor during holding is small compared to the power requirement during energization, it is expected that the control circuit voltage drop will be small, but this would need to be further evaluated due to the available voltage margin. However, without further evaluating the control circuit, if decreased voltage at the MCCs did cause the contactors to dropout, all motors would be automatically available for restart once voltage was restored. Therefore, no further evaluation is performed.

The contactor coils would not be damaged due to decreased voltage. The control circuit for each motor includes a contactor in series with a temperature switch, and in some cases, an interposing auxiliary relay, which provides alarm functionality only {Refs. 4.6.1-4.6.2). The MCC voltages are below the pick-up voltage for the contactor coils, which may prevent a motor from starting, but the contactor coil would not be damaged during a low degraded voltage condition. Since the contactor would not pick-up, the associated load would not energize and not see a starting transient. None of the control circuits contain fuses, and therefore there is no risk of motors being unavailable due to blown fuses.

8.5 Transient Voltage Dip Evaluation Section 8.2 determined a new LOV relay setpoint required to ensure that safety-related motors do not stall. This new setpoint is further evaluated to ensure that

I Analysis No. QDC-6700-E-2173 Revision 000 PAGE 17of18 I the LOV relays will not spuriously dropout for any expected voltage transient.

The LOV relays must not dropout for any expected EOG voltage transients. Diesel generator loading calculations 9390-02-19-1, 9390-02-19-2, and 9390-02-19-3 (Refs. 4.1.3-4.1.5) determined the largest expected voltage transients due to large motor starts on the EDGs. The calculations analyzed both LOOP/LOCA and LOOP without LOCA scenarios. The calculation results, for each EOG during the LOOP/LOCA scenario, show that the voltage recovers to more than 84% of 4.16 kV within one second following the start of any large 4 kV motor (Refs. 4.1.3-4.1.5). For LOOP without LOCA, the results of each calculation show that voltage recovers to more than 84% of 4.16 kV within one second following the start of the RHR service water pump motor (Refs. 4.1.3-4.1.5). Therefore, the 4.16 kV ESS bus voltage will recover above 3494 V (84% of 4.16 kV) within one second following the largest expected EOG voltage transient. This EOG recovery voltage value is greater than the maximum dropout voltage of the recommended LOV relay setpoint as shown below.

'Vrecovery = 3494V Vmax.dropout = [(OVtap

UVsetting) +Error] X PT Ratio Vmax.dropout = [(93V

95%) + 2.25V] X 35 = 3171 V The initial EOG transient voltage dip due to large motor starts, before one second has elapsed, will be less than 3494V. This dip is acceptable since it will be of a short duration (less than one second) and below the time-voltage characteristic curve of the LOV relay (Ref. 4.4.2) with the relay set at 95% of 93V.

The Unit 1, Unit 2, and 1/2 diesel loading calculations have been superseded by ETAP calculation QDC-6700-E-1503 (Ref. 4.1.2); however, the ETAP calculation does not maintain the transient voltage dip analysis. Per Engineering Judgment 3.3.1, the transient voltage dip analysis from the diesel loading calculations can be used for this evaluation. Furthermore, there is margin between the expected EOG voltage transient and the dropout voltage of the LOV relay.

Calculation QDC-6700-E-1503, Rev. 008 (Ref. 4.1.2) evaluates the voltage drop on the 4.16 kV ESS buses during LOCA block starts to ensure that the voltage at those buses recovers before the degraded voltage relays separate the buses from the degraded grid condition. The ETAP output reports from Calculation QDC-6700-E-1503, for the block start analyses, were reviewed. These reports include the ~OCA block start analyses for Unit 1 and Unit 2 with the reserve auxiliary transformer load tap changers in both automatic and manual mode. The voltage drop on the 4.16 kV ESS buses during the evaluated LOCA block starts remained above the maximum dropout voltage of the LOV relays.

8.6 Coordination with Protective Devices The phase protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 V ESS transformers are GE IAC-51 and GE IAC-66 relays (Refs.

4.6.3-4.6.6). Based on the instantaneous time-current curves for these relays, the operating time is less than 0.02 seconds for any pickup setting (Refs. 4.4.5-4.4.6).

I Analysis No. QDC*6700*E*2173 Revision 000 PAGE 18of18 I The ground protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 VESS transformers are GE PJC-11 relays (Refs. 4.6.3-4.6.6).

Based on the instantaneous time-current curve for this relay, the operating time is less than 0.05 seconds for any pickup setting (Refs. 4.4. 7). The LOV relay dropout time is greater than 1 second for all operating voltages. Therefore, the instantaneous units for the protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 V ESS transformers will clear faults faster than the LOV relays will dropout on low voltage.

8.7 Analytical Limits Consistent with the existing LOV relay settings, the upper and lower analytical limits for the LOV relay are selected as +/-5% of the recommended LOV relay nominal setpoint as shown below:

ALii = 93V x 95%

35 * (100% - 5%) = 2938V ALui = 93V x 95%

35 * (100% + 5%) = 3246V The safety-related motors that may be running during normal conditions were evaluated in Section 8.2 and shown not to stall with the 4. 16 kV ESS buses (i.e.

13-1, 14-1, 23-1, and 24-1) fixed at a voltage of 2850 V. The worst case expected EOG transient voltage dip was shown to recover above 3494 V in one second in Section 8.5. These voltage values are bounded by the selected lower and upper analytical limits for the LOV relay.

9.0 CONCLUSION

S 9.1 This calculation evaluated the LOV relay setpoint to ensure that the safety-related motors that may be running during normal conditions will continue to operate during the maximum 332.3 second degraded voltage time delay without stalling or tripping due to thermal overload relay operation. A setpoint of 88.35 V (93V OV tap, 95% UV setting) with +/-5% tolerance for the LOV relays was found to be high enough to prevent the stalling and tripping of safety-related motors that may be running during normal conditions and low enough to prevent spurious operation due to expected voltage transients. This satisfies the acceptance criteria. New upper and lower analytical limits for the LOV relay were calculated as 3246 V and 2938 V, respectively.

Calculation QDC-6700-E-2173 Revision 000 BE /ltot11t:tlv11 RB/ays DESCRIPTION The Type IA V relays are single phase induction disk ~lays designed to respond, with time delay, to either an increasing or a decreasing voltage, or both. Some models are frequency compensated, and some in-clude an instantaneous unit (hinged arma*

ture type). Most models listed in the Selection Guide include a target seal-in unit on all contacts.

The basic mechanism of all models is an induction-disk unit with either a tapped coil or a tapped resistor for setting pickup.

[In the overvoltage models, the relay is calibrated on increasing voltage to close the normally open contact at tap setting. The time dial adjusts the angle through which the disk rotates and, hence, the time delay.]

In the undervoltage models, the relay is calibrated on decreasing voltage to close the nonnally closed contact at tap setting. The time dial adjusts the angle through which the disk rotates at voltages above tap setting.

In the combined overvoltage and under-voltage models, the relay is calibrated on increasing voltages to close the normally open contacts at tap setting and on decreas-ing voltages to close the normally closed contacts at various percentages of tap set.

ting.

For the undervoltage and combined un-dervoltage and ovcrvoltage. relays, the two connecting plug S2 case is use.d to prevent false tripping when the relay is removed or replaced. Either plug completes the coil cir*

cuit and thus opens the normally closed contact used with undervoltage operation.

Both plugs are needed to complete the con-tact circuits.

APPLICATION OVERVOLTAGE RELAYS Type IA V overvoltage relays are used for protection against simple overvoltage, but other applications are also common. They are applied to ground detection, both on feeders and on ac generators, and they are also used in timed switching arrangements, where their dependability and accuracy make them preferable to purely mechanical timing relays.

Data subject to change without notice Attachments Page 84 of 821 IAV Time Delay Voltage Relays For protection against overvoltage in a three-phase system, psethe IAVSIA relay' (Fig. 2). For instantaneous protect.ion as well as time delay, use the IAV71B.

For the detection of grounds on un-grounded three-phase systems, two methods are in general use. One measures the zero sequence potential (Fig. 4), and the other measures the actual voltage between the sys-tem neutral and ground (Fig. 6).

. For the circuit of Figure 4, use Type IA VS ID, a low pickup relay which has its operating circuit tuned to the rated frequen-cy. The potential transformers used in this circuit are connected grounded*Y primary, broken-delta secondary. The* primaries should have ratings equal to the line-to-line voltage of the system, and the secondaries can have ratings of either 67 or 11 S volts.

Select a relay model with a continuous rating of three times the potential trans-former secondary voltage. This is necessary because, when a ground occurs, the zero sequence voltage may be up to three times the normal transformer secondary voltage.

Thus, with a potential transformer second-ary rated 67 volts, use a 199-volt relay coil.

For ground fault protection of ac rotating machines, use a circiiit similar to that shown in Figure 6 applying Type IA VS ID or IAVSIK relays. These are low-pickup relays whose coil circuits are tuned by capacitors to their rated frequencies. The circuits arc thus rendered only one-eighth as sensitive to the third harmonic as they are to the rated frequency.

In Figure 6, a distnl>ution transformer is connected between the machine neutral of the generator and ground. Normally there is no voltage on the transformer but during a fault, there is a voltage with a worst-case magnitude equal to the phase-to-ground value.

Greater sensitivity can be obtained by choosing a distribution transformer with higher secondary voltage. In such a case, the relay will not carry the fault voltage con-tinuously, and provision must be made to de-energize the operating coil using an aux-(Photo 8043218) fig. I. Type IAV71A U¥Drvoltage relay (aut of caso) iliary relay. The short-time rating for both IAVSlD and IAVSIK is 360 volts for 10 seconds.

The IAVSIM relay may be used for a definite time delay and the time is adjustable from 3 to 30 seconds by means ofa time dial.

Operating time is defined as the time to close the contacts with voltage suddenly raised from zero to the rated value.

UNDERVOLTAGE RELAYS For simple undervoltage protection, se-lect the IA V relay according to the time voltage characteristic required.

In.a typical automatic-preferred emer-gency throwovcr scheme, the undervoltage

co!ltacts of the IA VS4E relay are used to trip lhe circuit breaker in the normal.source circuit, and the auxiliary switch (52b) of this normal source breaker permits the voltage closing contacts of an IAVS lA relay i!I the emergency source to close its circuit break-er.

COMBINED UNDERVOLTAGE AND OVERVOLTAGE RELAYS Types IA VS3, IA V69, IA V70, and IAV73 relays are time-delay, over-and un-dervoltage relays having lwo 1=onlacts, one of which closes on overvoltage and the other on undervoltage.

The combined under-and overvoltage relays are made both "with and without time-delay adjustment. -Models IA V53, *69, and

-73 have time delays which are functions of the setting of the undervoltage contacts.

Model I~ V70 has a time dial which permits adjustment of time delay independently of the voltage settings.

TRIPPING CIRCUITS AND CONTACT RATINGS The current carrying rating of the con-tact circuit is determined by whether the.

relay has a seal-in unit and by the tap used on the seal-in coil. Without a seal*in unit the relay contacts will close and carry 30 amperes for tripping duty and 2 amperes continuously at control voltages of 250 volts de or less. Refer to Section 16 for data on target seal-in units.*

.Calculation QDC~6700-E-2173 Revision 000 AttachmentB Page 810 of B21 VOLTAGE RELAY TYPE IAV69A & B DESCRIPTION The IA V69 relay is a time delay undervoltage and overvoltage relay designed to be used wherever protection against an abnormal voltage condttlon is required.

The relay consists of an induction disk operating element which closes its left hand con-tacts when the voltage increases to a predetermined value and Us right hand contacts when the voltages decreased to another predetermined value.

The undervoltage adjustment ts independent of the over-voltage setting. A ttme dial is provided to permit easy adjustment of the operating time or the under-voltage setting which are interdependent.

The IAV69A relay has two target and seal-in devices, as indicated in Fig. 2, while the IA V69B relay has none; otherwise these two models are identical.

The lAV69 relay components are housed in an 82 double ended case with each contact connected between the upper and lower blocks while the op-erating coil ls connected to both blocks.

This permits the connection plugs to be removed or inserted with the operating coll always energized before the contacts are connected into their cir-cuits.

The normally open and normally closed contacts have a common point due to the use of a stngle control spring. The number of relays re-quired to protect a circuit is determined by the application.

APPLICATION These relays are used for protection and/or control of a-c circuits in reeponse to over and undervoltage condlttons.

A typical wiring diagram is shown in Fig. 7.

RATING The IA V69 relays covered by these instructions are available with 120 and 240 volt operating coils 50 or 60 cycles. The relay pickup and dropout can be adjusted to operate between 45 and 115 percent of rated voltage.

The coll will stand rated voltage continuously on any tap and tap voltage on taps above rated voltage.

The current closing rating of the contacts is 30 amperes at 250 volts or below.

The current carrying rating of the contacts ls limited by the target and seal-in unit where used as indicated in Table A.

When not limited by the target and seal-in untt, the contacts of the IA V69 relay will continuously carry and interrupt 0.3 non-inductive amps at 125 volts DC and 0.15 non-inductive amperes at 250 volts DC.

CHARACTERISTICS Operating Principles The induction disk operating unit consists of an aluminum dtsk which rotates between the pole faces of an electromagnet usuallycalleda U-magneL The operating coil produces the u-magnet's nux which tends to rotate the disk with a force pro-portional to the connected voltage.

The disk ts restrained by a spiral spring whose setttng deter-mines the relay pick up.

The d~s!t's motion ts restrained by a permanent magnet drag magnet whose restraint is proportional to the disk speed. The disk is fastened to a shaft to which the contacts are connected, The time delay is adjusted by changtng the distance the disk must travel to close lts contacts and the time-voltage relay character-istics are shown tn Ftg. 4. Adjustment of the tlme delay is made by rotating the ttme dial upon which the normally closed voltage stationar7 contact ls mounted.

Fig. 4A shows the percent o tap value to close the undervoltage contact at the different time dial settings.

The cover, which ls attached to the front of the relay casei contains the target reset mechanism and an inter ock arm whlch prevents the cover from being replaced until the connection plugs have been lnseryed.

The relay case is suitable for either seml-flush or surface mounting on all panels up to 2 inches thtck and appropriate hardware is available.

However, panel thickness must be indicated on the relay order to insure that proper hardware will be included.

Every circuit ln the drawout case has an auxi-liary brush as shown in Ftg. 5 to provide adequate overlap when the connecting plug ls withdrawn or inserted. It ls important that the awclliary brush makes contact as indicated in Fig. 5 wtth adequate pressure.

RECEIVING, HANDLING AND STORAGE These relays, when not included as part of a control panel, will be shipped in cartons designed to protect them a1!t9-inst damage. Immediately upon receipt of a relay, examine it for any damage sus-tained in transit.

If injury or damage resulting from rough handling is evident, me a damage clalm at once with the transportation companyandprompt-ly notify the nearest General Electric Apparatus Sales Office.

If the relays are not to be in-stalled immediately, they should be stored tn their original cartons in a place that ts free from mois-ture, dust and metallic chips.

Foreign matter collected on the outside of the case may ftnd lts way inside when the cover ts removed and cause trouble in the operation of the relay.

ACCEPTANCE TEST Immediately upon receipt of the relay, an inspection and acceptance test should be made to insure that no damage has been sustained in ship-ment and that the relay calibrations have not been disturbed.

Visual Inspection Check the nameplate stamping to insure that the model number, rating and calibration range of the relay received agree with the requisition.

Remove the relay from lts case and check by visual inspection that there are no broken or cracke<l molded parts or other signs of physical damage.

and that all screws are tight.

The drag magnet should be fastened securely in posttlon on Its mount-ing shelf. There must not be any metalllc particles or other foreign matter in the alr gap of either the drive magnet or the drag magnet.

Relay pickup settings between tap voltages can be made by control spring adjustment if desired by moving the spring adjusting ring. Check that the relay operates with one test plug removed.

When testing an IA V69A relay connect a DC source of power as shown in Ftg. d and check that the target seal-in units operate at or below the tap rating used.

2.

If adjustments are necessary, check the section Rotate the time dial to the No. 7 setting and on SERVICING.

check that disk rotates without binding or

touching the drag magnet or U-magnet.

Operate the target seal-in units and check that they operate without binding.

Electrical Tests Connect a variable source of power at rated frequency to studs 5 and 6 or 15 and 16, and check that the relay picks up at tap value +/-5% on at least two taps.

INSTALLATION PROCEDURE PERIODIC CHECKS AND ROUTINE MAINTENANCE In view of the vital role of protective relays in the operation of a power system lt is important that a periodic test program be followed. It ts recognized that the lr.terval between periodic checks will vary upon environment, type of relay, and the user's experience with periodic testing. Untu the user has accumulated enough experience to select the test interval best suited to his individual requirements lt is suggested that the following points be checked at an interval of from one to two years.

If after the acceptance tests the relay is held in storage before shipment to the job site, it is 1.

recommended that the visual and mechanical in-spection described under the section on ACCEPT-Repeat the visual and mechanical inspection described under section on ACCEPTANCE TESTS.

ANCE TESTS be repeated before installation.

Set the tap plug ln the 93 volt tap for the 120 volt relay or 186 volt t.ap for the 240 volt relay.

Set the time dtal at zero and check that the relay ptcks up at tap voltage +/-5 percent, Rotate the control sprtng adjuster until correct pick up is obtained.

The relay operating ttme can be adjusted by moving the drag magnet on lts mounting shelf ln towards the back of the case to decrease the time and out to increase tt. The outer edge of the drag magnet must always be at least 1/8" from the edge of the disk. If relay time ls out of adjustment by a considerable amount, check for friction causes such as particles tn the air gaps or cracked jewel bearings.

To change target seal-in tap settings, proceed as follows: -

The tap plug is the screw holding the rtght-hand stationary contact of the seal-tn unit.

To change the tap setting, first remove the connecting plug.

Then, take a screw from the left-hand stationary contact and place tt in the desired tap.

Next remove the screw from the other tap, and place it tn the left-hand contact. Thts procedure ts necessary to pre-vent the rtght-hand stationary contact from getttng out of adjustment. Screws should not 11.C. +

For cleaning fine silver contacts a flexible burnishing tool should be used. This consists of an etched roughened strtp of flexible metal resembling a superfine flle which removes corroded material quickly without scratching the surface. The flexlbtllty of the tool insures the cleaning of the actual points of contact.

Never use knives, files, abrasive paper or cloth to clean fine silver contacts. A burnlshtng tool as described above c~n be obtained from the factory.

RENEWAL PARTS*

It ts recommended that sufftctent quantities of renewal parts be carried in stock to enable the

prompt replacement of any that are worn, broken or damaged.

When ordering renewal parts, address the nearest Sales Office of the General Electi:tc Company,,

specify quantity required, name of the part wanted, and give complete nameplate data.

If possible, gtve the General Electric requlsltlon number on, which the relay was furnished.

CONCLUSION The results of the calculation show that the maximum continuous running load under the maximum loading scenario ls below the nameplate (2000 hrs/year) raUng of the DG.

Also, the worst voltage recovery after one second following the start of large 4kv motor (Core Spray Pump motor during LOOP / LOCA) is above 85% of DG terminal rated voltage for LOOP I LOCA and more than 84% of Bus rated voltage when the Service Water Pump Motor is started during LOOP without LOCA. This voltage recovery Is above the minimum voltage recovery of 80% per the DG specification K-2183 requirement.

Also, the analysis in Table 2 and e shows, and the detailed explanation under the Calculation and Results section shows that while some of the control circuits may dropout during the lowest portion of the voltage dip, no adverse effects are Identified and no protective devices are expected to oper~te. The calculation also shows that momentary voltage dip will not cause the travel time of any MOV to Increase any longer than allowable.

The calculation also shows that the starting time of automatically started 4-kv RHR pump motors Is under 4 seconds ~nd the sta~ing time for the. Cora Spray pump motor Is under 5 seconds. Starting times for all these pump motors are within the time setting requirements, which incl\\,ide the 5 second interval +/- 10% as required by Reference 72.

Also, the analysis in Table 2 and 6 shows, and the detailed explanation under the Calculation and !

Results section show that while some of the control circuits may dropout during the lowest portion o~ '

the voltage dip, no adverse effects are identified and no protective devices are expected to operate. ~

The calculation also shows that momentary voltage dip will not cause the travel time of any MOV to ~

increase any longer than allowable.

~

The calculation also show that the starting time of automatically started 4-kv RHR Pump motors 2C ~

& 20 are less than 4 Seconds and the starting time for Core Spray Pump motor is under 5 seconds. ~

Starting time of all these pump motors are within the time setting requrements, even with a +/-10% to) erance (Ref. 68) in the time setting interval.

Also, the worst voltage recovery after one second following the start of large 4kv motor (Core Spray Pump motor during LOOP I LOCA) is above 88% (for Unit 1 Division 1) and 84% (for Unit 2 Division 1) of DG terminal rated voltage for LOOP I LOCA and more than 84% of Bus rated voltage when the Service Water Pump Motor is started during LOOP without LOCA. This voltage recovery is above the minimum voltage recovery of 80% per the DG specification K-2183 requirement.
