PURPOSE The purpose of this Calculation is

. To evaluate the use of an ABB 27N undervoltage relay in the Second Level Under-Voltage (also called degraded voltage) protection scheme.

. Determine the relay trip (drop-out) and reset (pick-up) bands based on tha loop accuracy methods described in CI-01.00 Instmment Set-point Calculation Methodology (Reference 10).

. The analytical limits (AL) for the second level under-voltage relay pick-up are as follows:

1. The maximum pick-up voltage is equal the minimum 4KV ESF bus voltage under steady-state LOCA loading with the off-site voltage at the minimum expected value,

2. The minimum pick-up voltage is equal to the minimum 4KV ESF bus voltage required to start and run the LOCA required equipment.

. The allowable value (AV) will also be established by this volume and this number will be used in the Tech Spec revision which is being prepared to support the new relay settings.

DISCUSSION The second level under voltage relay scheme has a two fold function. It must ensure that there is adequate voltage following the LOCA block stan initiation for the ESF required equipment to start and run. It must also prevent the ESF buses from transferring to the on site source if there is adequate voltage from the oft-site source to operate the ESF equipment. Therefore the second level under voltage relay pick-up voltage (accounting for the various instrumentation errors) must fall between these values. In addition we want to prevent spurious transferring of the ESF buses to the onsite source a..d allow for minor changes to the off site grid with out impacting the degraded voltage relay settings. We have therefore based on engineering jtJgment chosen (for LER avoidance) to limit the maximum relay pick-up to 0.75% below the 4160 volt bus l Al voltage found in Calculation 19-AQ-02 Rev. 3 attachment 10.2. This setting will provide a degree of margin below the minimum expected 4KV Bus voltage under steady state LOCA conditions with the 345 Kv switch-yard at the minimum expected value.

Calculation 19-AQ-02 Rev. 3 Attachment 10.2 lists the steady state minimum voltage at the Bus 1 Al as 3938 volts. 100%-0.75% of 3938 than equals 3908 volts. The minimum reset point will be the minimum voltage at the 4KV bus which will ensure that all the ESF equipment required for LOCA will stan and run. The minimum voltage required by the ESF equipment will be taken from 19-AQ-02 Rev. 3 volume P Attachment 8.1 (3870 volts). The nominal second level under-voltage relay pick-up poirit has therefore been chosen to be mid way between the ,

maximum and minimum reset-points or 3889. We will call this nominal value NTSP. This calculation will assure that there is adequate margin for NTSP between the maximum and minimum allowable values when the total relay loop error is considered.

11. The relays utilized in the Second Level Under-Voltage scheme will be ABB l type 27N catalog number 41IT6375-HF(or 410T6375-IIF which has the same characteristics) . The relay pickup range is from 70 to 120 volts, the dropout range is 70% to 99%, the pickup time delay is instantaneous. The drop out time delay will be set at minimum (= 0.1 sec) The relay requires a 125 voit nominal DC source to operate. The relay will include the harmonic distortion fdter. The published relay tolerances from Reference 3, 4 and EXPRESSED AS A PERCENT OF SETTING are as follows:

a) Pickup and dropout setting repeatability with respect to l tempen' .e with a constant control voltage and the relay operating in an environment where the ambient temperature could vary between +10 to +40cc is 0.4%. We will call this 2S value ATE .

Am : A %

b) Pickup and dropout setting repeatability at a constant temperature and constant control voltage is i 0.1%. We will call this 25 value VA : .1 %

VA.

c) Pickup and dropout setting, repeatability over " allowable" de control power range is i 0.1%. The allowable de control power i range for a 125 volt nominal relay is 100 to 140 V DC. The Tech Spec. requires that when AC power is available to supply the battery charger the DC buses must operate between 121 and 139 volts. The published DC supply error is considered linear over the operating range per Reference 10, Engineering standard CI 01.00.

Therefore, the published error of 0.1% can be divided by 40 volt allowable range. In addition, data in the ABB type test Certificate Reference 5 shows that this is conse:vative. The variation then equals 0.0025%/ volt. We will call this 26 error PSE and P.sE = '045%

consider it to be *0.045% for our operntir.g range.

d) The radiation and humidity effects are considered negligible because the relays are not subjected to an environment with humidity or radiation above normal atmospheric conditions.

e) The 27N relay has been subjected to 6g ZPA either axis biaxial broad band multifrequency vibration with out malfunction or damage per ANSI /IEE C37.98 (reference 4). Therefore there is no seismic impact to the relay accuracy.

f) ABB tests indicate that there is no RFI interference effect associated with the relay. Therefore it is not considered a factor in this calculation (Reference 5).

i 13 The detection loop consists of the 4KV bus which we wish to measure, a potential transformer (PT) to convert 4KV to 120 volts and the ABB 27N relay.

The pts for DIV. I & 11 are Westinghouse PC-60 and, for DIV. III, GE type JVM-3. Both PT models have a ratio of 4200 - 120 volts and are class 1E. They conform to ANSI C57.13-1968 metering accuracy class for .03 class standard burdens W, X, M, & Y. The pts were purchased to Westinghouse drawing EN005, and GE data sheet 317A6131, and S&L j form 1815-L (Reference 1). The PT burden was established using E02- i 1 AP12 SH I1 R/W, E02-1 AP99 SH 36 R/D, E02-1 AP99 SH 38 IUU E02-1 AP12 SH 13 R/V, E02-1 AP12 SH 15 R/T, and E02-lHP99 SH 107 ,

IUL (Reference 7), and the load data from the vendor manuals (Reference 1). The PT burden consists of a CV2 relay, the 27N relay, a voltage ;

transducer, a lamp and a voltmeter (Note: the EMTs shown on E02- l 1 AP12 SH 13 R/V are being disconnected from the pts by mods AP- l 027,28, & 29). The total burden on the PT is 7.5VA with a possible j change in burden (caused by switching the voltmeter between phases) of 1 VA. From the performance curve found in reference 9, we can see that ;

for a change in burden of 12.5 VA the turns ratio correction changes 0.1%.

Therefore, if the actual change is 1 VA the change in PT turns ratio (EPT) would be .008% of rating. The curve also shows that the PT ratio correction factor should be .997, av 00x%

I4. Two relays will be installed in liv. I & II (one between phase AB and one between phase BC). The relay trip functions are wired in series so that both relays must trip in order for the protective action to be initiated. Only one relay must reset for the timer to reset, preventing transferring ofload to the diesel. Reference E02-I AP12 sheets 11 & 13 (Reference 7).

15. Two relays will replace the present single three phase relay in Div. III .

The new single phase relays will monitor phase AB and BC. The trip contacts are wired in series. All the elements must sense a degraded voltage for the protective function to be initiated. Only one relay must reset for the timer to reset, preventing transferring ofload to the diesel.

l M. 4 Illinois Power uses the GE methodology (Engineering Standard CI 01.00 -

Reference # 10) for determining critical set points based on instrument errors.

This methodology is statistically based. The desired probability for relay actuation l

! is 95% (per Reg. Guide 1.105 -Reference # 11). In order to determine the 95%

probability of either 2 relays actuating together or 1 of 2 relays resetting, the table l Attachment I was set up. The table was established by plotting the probability distribution that one relay would actuate assuming a normal distribution curve (see Are . won # A2). The equation for that plot was:

I Attachment 5 to U-602635 LS-94-013 CALCULATION 19-AN-19 REV. 2 VOL. D Page 13 of 40 PAGE M of /7

[ Dept /Div. E/EPED]

The probability that two will actuate together was determined by multiplying the probability of each of them together and plotting that curve accordingly. In this case that meant squaring the probability of one relay (since the probability for both relays is the same). The point on the Table in attachment I which equaled .95 was then found. This came out to be 1.96.

To determine the same o multiplier for when only one of the two relays needed to change state, the probability that the relays would fail to actuate was considered.

To do this, I minus the probability squared was tabulated (attachment 1). From this table the value for 95% confidence was found. This corresponds to a value of

.76.

Therefore, the 1.96 is to be used for a 95% probability that two relays will actuate together and 0.76 that one of the two will reset.

M.4a Two 27N relay contacts (in series) are required to initiate the time delay relay and the subsequent protective action. We have, therefore, determined that for a 1.96 6 deviation about the set point the relay loop will activate with 95% confidence level. We will call this Accuracy drop out (Ado). It can be expressed as:

Ado : 1.96 AL Ado = 0.4415 % of setting M.4b Only one of the two 27N relay contacts (in series) are required to reset the time delay relay and subsequently prevent the buses from transferring to the diesels. We have, therefore, determined that for a 0.76 deviation about the reset point the relay loop will activate with 95% confidence level.

The drop out can be adjusted between 70% and 99 % of the pick-up. We want to provide the maximum voltage to our equipment and still k.eep the relay pick-up as described above. Therefore we have chosen to set the drop-out at 99% of the pick-up or 3850 vats. j l

The Allowable drop-out value (DOLV) then is calculated by same method used for the pick-up above.

DOLv = 3832 + 3832 ^Vd" DOLV = 3847.6161 Volts at the 4 KV level 100 UU'Y DOLv120 = 110.2627 Volts at the 120V level DOLVI20 =

(.997 35)

The critical requirement, from a plant safety standpoint, is that all the equipment required to support the LOCA block start receive sufTicient voltage to stan and m n. Therefore the critical degraded voltage relay parameter is that the relay must reset at or above 3870 volts. This is equivalent to the relay minimum reset accounting for the appropriate relay errors.

The following table listing settings and analytical limits will be used as inputs for a Tech. Spec. change and the procedure for calibration of the relays. The voltage at the 120 volt level reflects the required voltage at the 4KV bus as scaled (transformed) by the Potential Transformer. The ratio of the 4KV voltage to the 120 volt level is 34.895:1. The Degraded Voltage relay senses and is calibrated for voltage at the !20 Volt level.

The calibration limits are established by drawing E02-1 AP04 sheet 001 and in the CPS calibration procedure. They are used as inputs to this calculation. The calibration limits are i0.04 volts. They are taken from section M3b.2 and are added and subtracted from the relay set-point at the 120 volt level. The 4 KV level value is equal to the 120 vo:t value times the PT ratio (35*0.997).

2. INSTALLATION l Mounting:

l The outline dimensions and panel drilling and cutout information is given in Fig. 1. i i Connections.

1 Typical external connections are shown in Figure 2. . Internal connections and ,

contact logic are shown in Figure 3. Control power must be connected in the proper polarity. ]

I For relays with dual-rated control power: before energizing, withdraw the relay from j q its case and inspect that the movable link on the lower printed circuit board is in j the correct position for the system control voltage. (For units rated 110vde, the 1 link should be placed in the position marked 125vdc.) I l These relays have an external resistor wired to terminals 1 and 9 which must be in place for normal operation. The resistor is supplied mounted on the relay.

These relays have metal front panels which are connected through printed circuit

! board runs and connector wiring to a terminal at the rear of the relay case. The terminal is marked "G". In all applications this terminal should be wired to ground.

3. SETTINGS

! PICKUP The pickup voltage taps identify the voltage level which the relay will cause the output contacts to transfer.

4 DROPOUT i The dropout voltage taps are identified as e percentage of the pickup voltage. Taps are provided for 70%, 80%, 90%, and 99% of pickup, or, 30%, 40%, 50%, and 60% of pickup.

Note: operating voltage values other than the specific values provided by the taps h,y can be obtained by means of an internal adjustment potentiometer. See section on testing for setting procedure. ;

i

TINE DIAL i

The time dial taps are identified as 1,2,3,4,5,6. Refer to the time-voltage charac-teristic curves in the Application section. Time dial selection is not provided on i relays with an Instantaneaus operating characteristic. The time delay may also be varied from that provided by the fixed tap by using the internal calibration adjust- i ment.

4 OPERATION INDICATORS The types 27N and 59N provide a target indicator that is electronically actuated at the time the output contacts transfer to the trip condition. The target must be manually reset. The target can be reset only if control power is available, AND if the input voltage to the relay returns to the " normal" condition.

An led indicator is provided for convenience in testing and calibrating the relay and to give operating personnel information on the status of the relay. See Figure 4 for the operation of this indicator.

Units with a "-L" suffix on the catalog number provide a green led to indicate the presence of control power and internal power supply voltage.

4. ACCEPTANCE TESTS Follow the test procedures under paragraph 5. For definite-time units.

select Time f [- Dial #3. For the type 27N, check timing by dropping the voltage to 50% of the dropout voltage set (or to zero volts if preferred for simplification of the test).

i

' For the type 59N check timing by switching the volwage to 105% of pickup (do not l

exceed max, input voltage rating.) Tolerances should be within those shown on page 5.

If the settings required for the particular application are known, use the l procedures in paragraph 5 to make the final tidjustments.

l S. CALIBRATION TESTS Test Connections and Test Sourgggi Typical test circuit connections are shown in , Figure 8. Connect the relay to a proper source of de control voltage to match its nameplate rating (and internal plug setting for dual-rated units). Generally the types 27N and 59N are used in applica-tions where high accuracy is required. The ac test source must be stable and free of harmonics. A test source with less than 0.3% harmonic distortion, such as a "line-corrector" is recommended. Do not use a voltage source that employs a ferroresonant transformer as the stabilizing and regulating device, as these usually have high harmonic content in their output. The accuracy of the voltage measuring instruments used must also be considered when calibrating these relays.

If the resolution of the ac test source adjustment means is not adequate, the arrangement using two variable transformers shown in Figure 9 to give " coarse" and

" fine" adjustments is recommended.

When adjusting the ac test source do not exceed the maximum input voltage rating of the relay.

LED Indicator:

A light emitting diode is provided on the front panel for convenience in determining the pickup and dropout voltages. The action of the indicator depends on the voltage level and the direction of voltage change, and is best explained by referring to Figure 4.

- The calibration potentiometers mentioned in the following procedures are of the multi-turn type for excellent resolutien and ease of setting. For catalog series 211 units, the 18 point extender board provides easier access to the calibration pots. If desired, the calibration potentiometers can be resealed with a drop of nail polish at the completion of the calibration procedure.

Octtina Pickuo and Drocout VoltaSgn Pickup may be varied between the fixed taps by adjusting the pickup calibration potentiometer R27. Pickup should be set first, with the dropout tap set at 99% (60%

on " low dropout units"). Set the pickup tap to the nearest value to the desired setting. The calibration potentiometer has approximately a +/-5% range. Decrease the voltage until dropout occurs, then check pickup by increasing the voltage. Re-adjust and repeat until pickup occurs at precisely the desired voltage.

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 the voltage until dropout occurs. Readjust R16 and repeat until the required setting has been made.

Settina Time Delav:

Similarly, the time delay may be adjusted higher or lower than the values shown on the time-voltage curves by means of the time delay calibration potentiometer R41. On the type 27N, time delay is initiated when the voltage drops f rom above the pickup value to below the dropout value.

GeneralInformation The HP3458A supports three tediniques for measuring true rms AC voltage, each offering unique capabilites. The desired measurement tedviique is selected through the SETACV comrnand. The ACV furdions wiH then apply the chosen (nethod for sutr,equent measurements.

The following section provides a brief desaiption of the three operation modes along with a summary table helpful in ,

choosing the tedinique best suited to your specife measurement need.

SETACV SYilC Synchronously Subsampled Computed true rms technique.. l This techruque provides excellent linearity and the most rmrate measurement results. It does require that the input signal be repetitive ( not random noise for example ). The bandwidth in this modois from 1 Hz to 10 MHz.

SETACV Af1A Analog Computing true rms conversion techni'que. ..

This is the measurement technique at powerajp or following an instrument reset. This mode wo64 well with any signal within its 10 Hz to 2 MHz bandwidth and pnmdes the fastast maasurement soeeds SETACV Rf1DM Random Sampled Computed true rms technique.

This technique again provides excellent Encarity. however tre overaR accuracy is the lowest of the three modes. It does not require a repetitive input signal and is therefore well suited to wideband noise measurements. The bandwidth in this mode is from 20 Hz to 10 MHz.
