JC-QlP81-90024 REV. 003 1.0 PURPOSE AND DESCRIPTION 1.1 The purpose of this calculation is to validate the Technical Specification Allowable Value and TRM Nominal Trip Setpoint for the 4160 V Division III Degraded Bus Voltage trip function.1.2 The incoming breakers for the Div. III switchgear are automatically tripped on a degraded bus voltage condition after a time delay. The degraded bus voltage condition is detected by sensors employing a one-out-of-two-twice logic. An undervoltage between 88% and 73% of nominal is considered a 'Degraded Voltage'. (Ref. 2.13)1.3 The time delay for a bus 'Degraded Voltage' condition is long enough to provide for the preferred power source (offsite power) to recover. This time delay duration is dependent upon the presence (or absence) of a LOCA signal. (Ref. 2.13)1.4 The upper and lower analytic limits for the Division III degraded voltage setpoints and time delays are derived from the station specific load flow and voltage drop calculation (EC-QI I 111-90028), Byron Jackson HPCS Pump Test Curve (#PC 74 1-S-1404), GE HPCS Motor Time Current Heating Curve (# 455HA550), GE HPCS Motor Efficiency and Power Factor Vs. Load Curves (# 455HA549), NEDO 10905-1, and GE HPCS Motor Outline Dwg. (#992C937CF).

The lower analytic limit for the voltage sensors is based on the capacity to start and operate required Class 1 E loads under accident conditions with degraded voltage levels present on the distribution system. Voltage sensing is performed by potential transformers located within the 4160 V switchgear for the division, and each potential transformer has a 4200 V/ 120V ratio. The HPCS system is designed to start and accelerate the HPCS Pump with 75% of 4000 V motor voltage (3000 V), per NEDO 10905-1. In order to continue operation indefinitely at the lower analytic voltage limit, motor heating must be limited to that imposed by curve #455HA550, which equates to rated current of the motor @ 434 A. Per PC 741-S-1404, the maximum power point for the HPCS Pump is less than 3100 Hp. At this operating point, the efficiency is 0.935, and the Power Factor is 0.93, per Curve #455HA549.

Therefore, at the maximum power point, with the motor drawing 434 A, the terminal voltage at the motor would be 3538 V. Per EC-QI 111-90028, the voltage drop is very conservatively calculated to be 5.41 V. This places the 4160 V bus at 3543.41 V for a sustained undervoltage condition limit. This correlates to a voltage of 101.24 V on a 120 V basis, and is the lower analytic limit (Reference 2.27).The upper analytic limit for the voltage sensors is based on prevention of unnecessary separation of the Class I E buses, under anticipated minimum voltage conditions of the offsite sources. Entergy System Planning Services performed, "Report on the Analysis of Potential for Sustained Degraded Voltage on the Off-Site Electric Grid at the Grand Gulf Nuclear Power Plant", dated November 9, 1990. This report provided the expected grid performance of the GGNS Offsite Sources under severe

• CALCULATION SHEET_ ENTERGY " SHEET 7 OF 37 CALCULATION NO. JC-Q1P81-90024 REV. 003 contingencies.

The results of this study determined that the 500 KV switchyard voltage could be as low as 0.994 Per-Unit, and the 115 KV switchyard voltage could be as low as 0.976 Per-Unit.Calculation EC-QI 111-90028, then conservatively analyzed the Class I E loads with the 500kV Offsite source at 0.975 Per-Unit and the 115kV Offsite source at 0.9675 Per-Unit.

It was determined that the Class 1 E system required loads would be adequately supported with 0.975 Per-Unit switchyard voltage available for the 500kV system and 0.9675 Per-Unit for the 115kV system. Therefore, it is appropriate that the upper analytic limit for the degraded voltage setpoint determinations be based on the corresponding voltage available at the respective 4160 V Class IE buses, with 0.975 Per-Unit 500kV system driving voltage or 0.9675 Per-Unit 115kV system driving voltage in each switchyard, under accident conditions.

The lowest available transient voltage on the Division III 4160 V bus under these conditions has been calculated to be 3359.2 V, which occurs during the start of the HPCS pump, with bus voltage recovery to 3880.9 V within 5 seconds. This condition provides an initial terminal voltage at the HPCS pump motor of 3329.25 V, with voltage increasing as the motor accelerates.

The second lowest transient voltage step is 3846.34 V, with bus voltage recovery to 3904.16 V, within 5 seconds. This interval is after the HPCS pump motor is already started, therefore the acceleration time of this load is not a factor. All other bus voltage steps are calculated to remain above 3880.9 V. The recovery voltages referenced include the start demand of the next sequence interval, therefore actual recovery voltages at the end of each step following load acceleration and prior to the next sequence would be above thesevalues.

Therefore, if the HPCS motor can accelerate its load at the minimum transient voltage within the allowable time delay band, the recovery voltage predicted would form the upper analytic limit for degraded voltage considerations during the sequence when the HPCS pump motor starts. For all successive intervals, using the lowest available bus voltage step will ensure that other equipment sequencing will not inadvertently actuate the Division III bus degraded voltage sensors. As stated above, this correlates to a bus voltage of 3846.34 V. This value would bound all required conditions for the HPCS system to remain connected to offsite power, without prematurely separating from this source, provided that the time delay is set sufficiently to account for HPCS motor start time. Therefore, the overall bounding upper analytic limit is 3846.34 V (109.89 V on a 120 V basis), and the appropriate sensor time delay interval will also be based on this value (Reference 2.27).Division III has two distinct time delays associated with degraded voltage sensing.One time delay is active when no accident signal is present, and the other is active when a safety injection signal is present for Division III.The lower analytic limit for the safety injection condition time delay is based on providing the capability to successfully start the HPCS pump at the lower analytic limit of the degraded voltage sensors without segregating from the offsite source. This requires that the time delay be of sufficient duration to allow for acceleration of the A CALCULATION SHEET ENTERGY SHEET 8 OF 37 CALCULATION NO. JC-Q1P81-90024 REV. 003 HPCS pump motor under these conditions.

Using the previously established minimum HPCS motor starting voltage available from a viable offsite source of 3329.25 V, the acceleration time for the HPCS pump motor has been determined to be no more than 3.28 Seconds. This condition conservatively bounds the acceleration time required at the lower analytic limit bus voltage of 3543.41 V. Therefore, 3.28 seconds is the lower analytic limit for the safety injection condition degraded voltage time delay.The upper analytic limit for the safety injection condition degraded voltage time delay is derived from the required time response for the HPCS system to achieve necessary injection flow within 27 Seconds of accident initiation.

This further requires that the HPCS system be connected to a viable power source within 10 seconds to achieve this goal. The limiting case for this upper limit is when offsite power is available but degraded (i.e, above the Loss of Voltage settings, but below the lower analytic limit for the degraded voltage sensors), with an accident signal present. This is because the degraded voltage function trips the incoming source only, therefore requiring the subsequent sensing and time delay from the Loss of Voltage function to connect the Emergency Diesel Generator (EDG) to the bus. The EDG receives a separate safety injection signal, so the EDG start time and the total voltage sensing sequence described will occur concurrently.

This limits the allowed combined sense and actuate times for the degraded voltage and loss of voltage functions to no more than 10 seconds total. It is desirable that the degraded voltage time delay be of a longer duration than the loss of voltage time delay, based on original system design.Therefore, a 6 Second upper analytic limit is allocated to the degraded voltage time delay. Correspondingly, a 4 Second upper analytic bound is thus established for the loss of voltage time delay by this selection.

The design for the Division III Degraded Voltage detection was provided by GE under FDDR JB 1-2099. The applicable setpoints were determined by this design document, without providing GGNS with documented basis justification at the time.Subsequently, per GGNS request, GE provided a summary of an evaluation that was performed to justify the nominal 5 minute degraded voltage time delay, no LOCA setpoint (MPGE-86/03 1). The actual evaluation resides with GE, and was not provided to GGNS. This evaluation was based on nominal setpoint values, with no apparent consideration for uncertainties.

GE did not provide a Design Specification Data Sheet for the Degraded voltage function, possibly due to the unique application, i.e., the function did not meet the conventional "instrument loop" configuration.

Because no Design Specification Data Sheet was generated, no definitive Analytic Limit determinations were provided to GGNS.The appropriate method to determine an upper Analytic Limit for this parameter is to determine a minimum that the bus voltage could degrade to, and evaluate the maximum permissible time that the system could sustain this voltage without causing equipment damage or loss of function due to protective device actuations, such as SHEET 9 OF REV.CALCULATION NO. JC-O1P81-90024 circuit breaker or thermal protection trips. This is to ensure that the system will maintain the capability to automatically respond to a subsequent LOCA signal, without incurring functional impairment due to the offsite source degradation.

While the capability to provide uninterrupted functional capability due to offsite source degradation has been a relevant consideration from original system design, the inherent historical assumption has been to consider the level of degradation that would be expected, and assume a loss of the offsite source completely below that point. This almost certainly formed the basis for the original system settings.

During the Electrical Distribution.

System Functional Inspections performed by the NRC in the early 1990's, certain utilities received questions relating to system performance if the voltage theoretically degraded below this level, but remained above the loss of voltage setpoint.

Apparently, the transmission systems for some plants may have been marginally configured such that voltage degradation to sustainable values at the transmission system level could represent an extremely degraded value in the plant Switchyard.

This consideration is further discussed as it relates to GGNS.For GGNS, the existing time delay settings are acceptable, provided that the degraded voltage remains sufficiently high to start the HPCS loads. This correlates to a motor terminal voltage of 75% of the motor base voltage for HPCS system motors. Review of calculation EC-Q 1111-90028, has determined that the bounding percent voltage drop from the offsite source to the HPCS pump motor is considerably less than 15%, even under the motor start demand conditions.

A 15% drop will be conservatively assumed for this discussion.

The HPCS system motors are designed to start with 75%of motor rated voltage. This is 3000 V for the HPCS pump motor. 3000 V is less than 73% of rated bus voltage (4160 V). Therefore, the HPCS pump motor would be expected to start for offsite source degraded voltage conditions down to 88% of rated offsite source voltage (73% + 15% = 88%). The remaining consideration for continued relay timing limitations would be the motor heating limits once the motor has started. Motor heating must be limited to that imposed by curve #455HA550.

Per PC 741-S-1404, the maximum power point for the HPCS Pump is less than 3100 Hp.At this operating point, the efficiency is 0.935, and the Power Factor is 0.93, per Curve#455HA549.

Therefore, at the maximum power point, with 3000 V available at the motor, the current would be 511.83A (1.18 PU) under these conditions.

Per the motor heating curve, operation at this current level can continue in excess of 600 seconds, which is significantly longer than the present time delay settings require.Thus, the present settings are justified for offsite source degradation levels down to at least 88% of rated.A discussion of the practical operating limits for the Entergy Transmission system and system generators, provides confirmation of the adequacy of this anticipated degradation level. The Entergy Transmission Planning Guidelines impose the requirement that substation bus voltage capabilities be maintained at no less than 92%of rated, even under severe contingency analysis conditions.

In fact, this represents an extreme case for system voltage level degradation limits, because the generation CALCULATION SHEET__ ENTERGY SHEET 10 OF 37 CALCULATION NO. JC-QlP81-90024 REV. 003 facilities generally are forced to reduce generation (including reactive generation for voltage support) at about 95% of rated voltage, to protect individual generators from thermal damage due to over-excitation.

In the case of severe sustained degraded voltage conditions, this would almost certainly lead to load isolation or system voltage collapse.

In either case, loss of the offsite source or system voltage recovery to acceptable levels for continued generation would be an expected consequence in very short order. Additionally, GGNS is located within the system such that transmission system voltage levels very closely match generation station Switchyard output voltages.

GGNS 500 KV Switchyard nominal voltage is 1.02 PU. Thus any degradation seen in the GGNS Switchyard would also be seen by the supporting generation.

Therefore, sustained degraded grid conditions below about 95% would not be expected to occur for GGNS, and System Planning Analyses ensure the capability to maintain at least 92% Substation voltage under severe contingency considerations.

With these considerations, it would be appropriate to select 600 seconds (10 min.) as the upper analytic limit for the Division III Time Delay, No LOCA. For additional conservatism, this limit will be set at 360 seconds (6 min.). This provides adequate time for voltage recovery to above the degraded voltage set-point, while ensuring the continued automatic availability of the system, should a subsequent LOCA signal be received.

The lower analytic limit for this parameter should be based on a reasonable period to allow time for recovery.

It is to be selected to provide an equivalent margin from the nominal trip setpoint as the margin allowed from the setpoint to the upper analytic limit (i.e. I min.). Therefore, the lower analytic limit for the Time Delay, No LOCA is 4 minutes.1.5 The design consideration for the subject instrumentation is: Degraded Grid Voltage 1.6 This calculation is performed in accordance with the methodology of GGNS-JS-09, which is based on the 'square root sum of the squares' (SRSS) technique for combining statistically independent uncertainty components.

4.2 Assume Radiation Effects (RE) and Humidity Effects (HE) for the undervoltage and time delay relays are negligible.

These components are located in a mild environment.(Ref. Section 3.1.3 and 3.2.3)4.3 Assume Seismic Effects (SE) are negligible for both the undervoltage and time delay relays. The relays are seismically qualified per GGNS QP 425.00 Vol. 1, Rev. 1.4.4 Assume Temperature Drift (TD) is encompassed by the Temperature Effect (TE) for the undervoltage relays.4.5 Insulation Resistance Effects (IR) are assumed to be negligible since the loop cabling is located in a mild environment (control building).

4.6 Not Used.4.7 Per Reference 2.21 and 2.22, the potential transformers at the bus are G.E. type JVM-3. This type of potential transformer has an accuracy class of 0.3 at W and X burdens when operated at 58% of rated voltage. Based on the available burden information for the circuit components depicted on Ref. 2.16 and 2.18, the burden is assumed to be less than X and the accuracy of the potential transformers is assumed to be 0.3. (See file documentation for available circuit component burden data)4.8 Assume Temperature Effects (TE) and Temperature Drift Effect (TD) for the time delay relays are negligible.

The normal ambient temperature at the relays is within the vendor specified normal ambient temperature (Ref. 2.23).4.9 Assume Power Supply Effects (PS) for the time delay relays are negligible.

The supply voltage variation is expected to be encompassed by the voltage variation margin available

(+/-10% of rated voltage, Ref. 2.23).4.10 The vendor does not specify a Temperature Effect, Temperature Drift or Power Supply Effect for the undervoltage relay timing function.

& Test Equipment Effects -"Cl," (Ref. 2.1)Per Reference 2.8, a Fluke 45 Digital Voltmeter (or Fluke 8600A) is used to monitor the trip point of the undervoltage relays during calibration.

The uncertainty data for a Fluke 45, taken from Ref. 2.10, will be used to estimate the M&TE effects. The reference accuracy of the Fluke 45 is: RAF 4 s = +/-(0.2% reading + 0.1 V)The reference accuracy above is for the 0-300V scale, medium resolution.

This value is valid for ambient temperatures between 18 0 C and 28 0 C (64.4°F to 82.4°F). Since the expected temperature at calibration (104TF, i.e. 40'C) is outside the given range, a temperature correction factor from Ref. 2.10 must be applied. This correction factor is stated as: '<0.1 times the applicable accuracy specification per degree C for 0C to 18 0 C and 28°C to 50 0 C (320 to 64.40 and 82.40 to 122 0 F). The temperature correction factor for this application is <0.1 (40-28) or 1.2.The 'reading' will be assumed to be 104.6 V, the nominal trip setpoint.

NCALCULATION SHEET__ ENTERGY SHEET 32 OF 37 CALCULATION NO. JC-QIP81-90024 REV. 003 As stated previously, with 0.975 Per-Unit switchyard driving voltage, the lowest transient voltage on the Division III 4160V bus has been calculated to be 3359.2V (95.80V on a 120V basis) which occurs during the start of the HPCS pump, with voltage recovery to 3880.9 V (1 10.88V on a 120V basis). This condition provides an initial terminal voltage at the HPCS pump motor of 3329.25 V. Assuming a constant terminal voltage of 3329.25 V (i.e. no voltage recovery as the motor accelerates) the acceleration time of the HPCS pump motor has been determined to be no more than 3.28 seconds. Therefore, the actual recovery time to at least 3880.9 V would be no more than 3.28 seconds (the Lower Analytic Limit of the time delay setting).The present pickup (reset) point for the under voltage relays is 105.65 V and the dropout (trip) point is established by the 99% tap setting at 104.60V. Assuming worst case performance of the relays, the trip could occur at the Upper Allowable Value of 107.53 V and the reset could occur at 108.60 V (i.e. 1.01 x 107.53).Given the above, the bus voltage would recover above the reset point of the relay 108.60 V (3801 V) to at least 110.88 V (3880.9 V) before the time delay times out (even with the worst case performance from the time delay). Therefore, the reset value will prevent spurious segregation from the preferred off site source and is acceptable.

8.0 CONCLUSION

Voltage Trip: The calculated setpoint range and the Upper Allowable Value are conservative with respect to the existing plant settings.

The existing Lower Allowable Value (101.67 V) is non-conservative with respect to the calculated value.Time Delay -LOCA The initial calculated setpoint range would not support the existing LOCA Time Delay setpoint.

Margin reduction techniques were used to remove some conservatism from the calculated values. With the reduced uncertainty, the existing plant setpoint was shown to be acceptable.

The existing Allowable Value (3.6 seconds) is non-conservative with respect to the calculated Lower Allowable Value for the LOCA Time Delay..Time Delay- No LOCA The calculated setpoint and allowable values are conservative with respect to the existing plant setpoints and allowable values. Therefore, the existing plant setpoint is acceptable.

The spurious trip and LER avoidance criterion is met for all values except the time delay lower allowable value. LER avoidance is not met using the recommended lower allowable value.

I-T-E SOLID STATE VOLTAGE RELAYS PAGE.-PAGE 9 TESTING 1. MAINTENANCE AND RENEWAL PARTS No routine maintenance is required on these relays. Follow test Instructions to verify that the relay is in proper working order. Ve recommend that an inoperative relay be returned to the factory for repair; however, a circuit description and/or a schematic diagram are available for those who wish to attempt repairs. Contact your local sales engineer or contact the factory. These relays have a control relay as the output stage. This output relay may be ordered from the factory. Replacement target head assembly may be ordered should the target be mechanically damaged. (See page it)Also avallable from the factory are circuit card extenders which are recommended for usa when calibrating the relays. All these relays use the 18 point extender, catalog 200XOOl8.OlAWOUT ELEMENT Drawout circuit boards of the same catalog number are Interchangeable.

The board is reaoved by using the metal pull knobs on the front pIael. The circuit board is identified by the catalog number on the front panel and a serial number stamped on the under side of the circuit board.CAUTION A1TACH-MFN4T Simce troubleshooting entails working with energIzed equipment, caution XTOJcIeRF

If a control wiring Insu-lation test Is required, withdraw the circuit board from the case before applying the test voltage.Partial withdrawal to disconnect circuit board from connector In rear of case is adequate.L. ACCEPTANCE TESTS Follow calibration procedures under paragraph

4. Select Time Dial 13. For ITE-17N, Chock timing by dropping voltage to 503 of pickup. For ITE-S5N, by Increasing voltage to 110 percent of pickup. Tolerances should be within those listed on page S. Calibration wy be trImmd or adjusted to the final settings required for the application at this time.CAUSUTN TESTS Connect the relay to the proper source of control voltag (to match the relay nameplate rating). for relays with dual rating, be sure the movable link an the circuit board is in the correct position.

Connect the relay to the AC test source and to a timer. Typical test cir-cuits are shom in figure 6.. If very accurate settings are required for a particular applica-tion, say within -+311 of a given voltage, & stable, harmanlc free test source is required.

We recommend a "lIne corrector" type device be used in these cases. See figure 7 for the reco-men-ded AC test source circuit. The line corrector typically has less than 0.32 hamonic distortion.

A light emitting diode indicator is provided an the front panel for convenience in testing. its action is Instantaneous, thereby removing the uncertainty caused by the time delay before the output contacts transfer.

The action of the indicator depends an the voltage level and the direction of voltage change and is best explained by referring to figure 4.Pickup my be varied between the fixed taps by adjusting the pickup calibration potentio-meter R27. Pickup should be set first, with the dropout tap set at 552, and the pickup tap sat at the nearest value to the desired setting. Decrease the voltage until dropout occurs, then recheck pickup by Increasing the voltage. ReadJust until pickup occurs at precisely the desired voltage.

18-7.A I.77 PAGE 10O I-T-E SOLID STATE VOLTAGE RELAYS Potentiometer R16 is provided to adjust dropout. Set the dropout tap to the next lower tap to the desired value. Increase the input voltage to above pickup and then lower until dropout occurs. Readjust R16 and repeat until the required setting has been made.Similarly, the time delay may be adjusted higher or lower then the values shown on the time-voltage curves by means of the time delay calibration potentiometer R41. Time delay is initiated when the voltage falls from above pickup to below the dropout setting.If the voltage does not return to above the pickup setting by the end of the time delay period, the output contacts will transfer.The locations of the calibration potentliomters are shown in fIgure 5. The potentiometers are multi-turn types for excellent resolution and ease of setting.BUILT-IN TEST FUNCTION A built-in test function is provided for convenience in functlonally testing the relay and associated devices. CAUTION: tests should be made with the maim circuit de-energized.

If tests are to be made on an energized circuit, take all necessary precautions.

The test button is labelled TRIP. For the ITE-27N, when the button is depressed, at undervoItage condition is simulated, and the relay will operate. For the ITE-55N, an overvoltage condition is simulated.

For relays with time delay function, you must hold the button in for as long as the set time delay to get an operation.

The line corrector stabilizes the line voltage and has low har-monic content. Ferroresonant regulators are not acceptable due to high har-monic content of the output waveform.

Two variable transformers provide coarse and fine voltage adjustments.

The voltmeter accuracy must be sufficient for the setting being made: +/-1/4 percent is recommended.

The relay should be energized for 10 to 15 minutes before settings are made, to allow the circuits to stabilize.

is-' n Attachment 2 to JC-Q1P81-90024 SECTION 1 SHEET 3 OF 17 GENERAL INFORMATION PURPOSE The BEI-Z7 Undervoltage, BE1-59 Overvoltage and the BEI-27/5g Under/Overvoltage Relays are solid-state devices which provide reliable protection for generators, motors and transformers against adverse system voltage conditions.

Application Electric power systems are designed for constant voltage operation.

Loads utilizing commercial electric power are designed to operate at a constant input voltage level with some tolerance.

Radical voltage variations on a power system are indicative of a system malfunction.

Protective relays which monitor system voltage and provide an output signal when the voltage goes outside predeter-mined limits, find a variety of applications.

Some of these applications include motor, and transformer protection, interface protection for cogeneration systems, and supervision of automatic transfer switching schemes.Motor Protection When selecting the type of protection for motor applications, the motor type, voltage rating, horsepower, thermal capability during start-up, and exposure to automatic transfer restarting following a voltage interruption need to be con-sidered. During motor start-up, a low terminal voltage condition will inhibit the motor from reaching rated speed. The 8E1-27 undervoltage relay will detect this low voltage condition and trip. Critical applications requiring continuous motor operation and applications where overloads during start-up may be main-tained for a given time period, usually have a definite time or inverse time delay characteristic incorporated to avoid unnecessary tripping during low voltage dips. If the undervoltage condition persists for the established time delay, the relay output contacts are connected to the station aarm annunciator panel, allowing the station operator to take corrective action. The BEl-59 Overvoltage relay is applied to insure the voltage does not exceed the limits established by the machine manufacturer for proper operation.

Overvoltage con-ditions stress the insulation level of the equipment and may cause a dielectric breakdown resulting in a flashover to ground.Automatic Transfer Switching Distribution substations are sometimes designed with duplicate supply circuits and transformers to eliminate service interruptions due to faults located on the primary feeder. In order to restore service within a given acceptable time period, automatic transfer switching can be applied to initiate the throwover from primary power to the alternate power source. The BE1-27 Undervoltage Relay can initiate switching after a given time delay to void transfer switching during temporary low voltage conditions.

To return the substation to normal service upon the restoration of primary voltage, the BEl-59 overvoltage relay supervises the transition to its normal operating condition.

1-1 9*WWa~e Ek-e" Attachment 2 Cogenerati on to JC-QIP81-90024 SHEET 4 OF 17 utilities employ the use of a voltage check scheme to supervise reclosing at the substation when cogenerators are connected to a radial distribution feeder and the cogenerator is capable of supplying the entire load when the utility circuit breaker Is open. During a faulted condition, the utility requires the cogenera-tor to be disconnected from the system before reclosing the utility breaker. If the cogenerator is connected to the system, the utility will reclose to an energized line.This could result in reconnecting two systems out of synchronism with each other. A BE1-27 undervoltage relay monitoring the line voltage will inhibit reclosing of the utility circuit breaker if the line is energized by the cogen-erator.At the interface between the utility and the cogenerator, overvoltage and under-voltage relays are Installed as minimum protection to provide an operating-voltage window for the cogenerator.

During faulted conditions, when the cogenerator may become overloaded, the BE1.27 Undervoltage Relay will detect the decline in voltage and remove the cogenerator from the system. The BE1-59 Overvoltage Relay will protect the system from overvoltage conditions that occur when power factor correction capacitors are located on the feeder.Transformer Protection Voltage relays can be applied to protect large transformers from damage as a result of overexcitation.

The concern for transformer overvoltage may be mini-mized in many power system applications where proper voltage control of the generating unit is provided.

However, where a tap changing regulating trans-former is located between the generating source and the load, some form of voltage protection may be required to supplement the tap changing control and to prevent equipment damage due to over, as well as undervoltages resulting from a failure of the tap changing control. The BE1-27/59 Under/Overvoltage Relay is well suited for these applications.

Ground Fault Detection In a three-phase, three-wire system, a single conductor may break or the Insula-tion may deteriorate resulting in a high resistance ground fault which may not be detected by the overcurrent relays. This condition, however, may be sensed by an overvoltage relay connected to a grounded wye, broken delta set of poten-tial transformers (PT's) as illustrated in Figure 1-1. With this connection, and a sensitive relay setting, an unbalanced voltage condition, such as described above, can be quickly detected and isolated.Y.i Figure 1-1. Ground Fault Detection 1-2 M.-.

The Type IJF Is an induction disk type relay mounted in a single unit drawout case. It has two shaded-pole U-magnet type driving elements acting on opposite sides of the disk. One of these, the oerating element, is designed to drive the disk in e direction to close the left contacts and the other, the restraining element to drive le disk It the contact-openingdirectionon relays having single-throw contacts and to close the right contacts on relays having double-throw contacts.

The disk shaft Is restrained by a spiral spring, the principal purpose of which is to hold the contacts open when the relay is do-energized.

The motion of the disk is retarded by permanent magnets to give the correct time delay for closing the contacts.There is a seal-in unit mounted to the left of the shaft on the Type IJF5IA and UFSIB relays.The Type IJF52A relay has a seal-in unit mounted on both sides of the shaft. This element has Its coil in series and its contacts in parallel with the main contacts such that when the main contacts close, the seal-in element picks up and seals In.When the seal-in element picks up it raises a target Into view which latches up and remains exposed until released by pressing a button beneath the lower left corner of the cover.The case is suitable for either surface or semaflush panel mounting and an assortment of hardware is. provided for either mounting.

The cover attaches to the case and also carries the reset mechanism when one is required.

Each cover screw has provision for a sealing wire.The case has studs or screw connections at both ends or at the bottom only for the external connections.

The electrical connections between the relay units and the case studs are made through spring backed contact fingers mounted in stationary molded Inner and outer blocks between which nests a removable connecting plug which completes the circuits.

The outer blocks, attached to the case, have the studs for the external con-nections, and the inner blocks have the terminals for the internal connections.

The relay mechanism is mounted in a steel framework called the cradle and is a complete unit with all leads being terminated at the inner block.This cradle is held firmly in the case with a latch at the top and the bottom and by a guide pin at the back of the case. The cases and cradles are so constructed that the relay cannot be inserted in the cae upside down. The connecting plug, besides making the electrical connections between the re-Te ctive blocks of the cradle and case, also lock latch In place. The cover which is fastened to the case by thumbscrews, holds the connecting plug in place.To draw out the relay unit the cover is first removed, and the plug drawn out. Shorting bars are provided in the case to short the current transformer circuits.

The latches are then released, and the relay unit can be easily draw out. To replace the relay unit, the reverse order is followed.A separate testing plug can be inserted In place of the connecting plug to test the relay in place on the panel either from its own source of current and voltage, or from other sources. Or, the relay unit can be drawn out and replaced by another which has been tested in the laboratory.

APPLICATION The Type UJF frequency relay. are recom-mended for protection of synchronous apparatus against overapeed or underspeed conditions caused by loss of load In the case of generators, or loss of supply power In the awse of motor and condensers.

The relays can be used to operate protective de-vices, or to sound an alarm whenever the frequency of the circuit varies by a predetermined amount above or below normal.RATINGS These relays are available in frequency rating from 25 to 60 cycles and voltage ratings of II and 230 volts.The current closing rating of the contacts is 30 amperes for voltages not exceeding 250 volts.The current-carrying ratings are afected by the selection of the tap on the seal-in coil as Indicated In Table L TABLE I 7 1 Amperes, AC or DC ,.t~n 2-Amp TaplO .2 Amp Tap Tripping Duty carry continuously 30 3$5 0.3-~ -Thea.snas c~a db not purport to o@m'r all details or iuaiations in equitinte nr ev prvvid* for*vizry possible contingency to bo mat in conection wiith **u~jtaj",a Vpacation or aefatasano.

The tap setting used on the seal-in element is determined by the current drawn by the trip coiL The 0.2-ampere tap is for use with trip coils that operate on currents ranging from 0.2 up to 2.0 amperes at the minimum control voltage. 1f this tap Is used with trip coils requiring more than 2 amperes, there Is a possibility that the 7-ohm resistance will reduce the current to so low a value that the breaker will not be tripped.The 2-ampere tap should be used with trip coils that take 2 aptes or more at minimum control voltage, p ded the tripping current does not exceed 30 amperes at the maximum contro Voltage.If the trtpptng current exceeds 30 amperes 2A auxiliary relay should be used, the connections being such that the trUping current does not paes througthe contacts or the taget and seal-in coils of the protective relay.Frequency Relays Type U7F GEl-19008 8URDENS Burden data for the 55-60 cycle under frequency relay and 60-65 cycles overfrequency relays are given in Table I at 115 volts 80 cycles.Burdens listed are total burden of relay.TABLE 17 Relay volt Power Amps Factor Wts FW51A 8.7 .99 8.6 IJVSIB 5.8 798 j 57 Total burdens for the Type IMZA relay at 115 volts are as follows.TABLE IM Volt Power watts Amps Factor 25 6.3 .9 1 6 6010.7 .89 9.5 RECEIVING, HANDLING AND STORAGE These relays, when not included as a part of a control panel, w be shipped in cartons designed to protect them against dmunae. Immediately upon receipt of the relay, an mination should be made for any damage sustained during shipment If or damage resultlng from rough handlin isevident, a claim should beflledatoncewith the transprta company and the nearest Sales Office of the General Electric Company notified promptly.Reasonable care should be exercised In un-p g the rela in order that none ot the parts are Wur or the Ads disturbed.

If the relays are not tobe Intalled Immediately, they should be stored In their original c a place that is free from moisture, dust,=r4 metallic chips. Foreign matter collected on te outasie of t ce may find its way inside when the cover is removed and came trouble In the operti of the relay.INSTALLATION LOCATION The location should be clean and dry, free from dust and excessive vibration, and well lighted to facilitate inspection and testing.MOUNTING The relay should be mounted on a verta surface. The outine and panel diagram Is shown In Fig. 12.CONNECTIONS Internal connection diagrams for the various relay types are shown in Fig. 7 to 9 inclusive.

Typical wiring diagrams are given in Fli lOand 11.One of the mounting studs or screws should be permanently grounded by a conductor not less than No. 12 B&S gW copper wire or its equivalent.

AtDCIUA.tZZS When external capacitors, and In same cases resistors, are funished with relays they are Ide-tifled by means of serial number. These numbers ae of the form X-lO2 or OA.-155 The purpose of these numbers is to insure that emrlay, when installed, will be provided with the samb-Wuxlaries with which it wan calibrated at the factorM The reason for this precaution Is to eliminate the variatlon In callbablons of the relays which would otherwise result from the variation tn elec-trical properties of the auxillaries.

In general ternmi a Ratio Correction Factor (RCF) greater than I-for instance, I .002-will ca- c the meters and inlsrumebts in the secondar" circuit to read low (0.2 percent low for an RCF of 1.002).A negative (lagging) phme-angle error will cuse a wattmetet in the secondary circuit of a potential trnmfotmer to read high (for the normna situation of lagging line power factors).

This results from the fact tha-, t 12n" potenial phase-amnigIerror decreases the power acto- angle of the secondary ch'ut over what i w ina e primary rcuit. by dmcesing deogle by which the current lap the voltage as shown in Fig.9.
