C//N)1 nh.2/43 1.0 OBJECTIVE To determine the setpoints of the Model 27N Undervoltage Relays for degraded grid protection at Unit #1 and Unit #2 g per Electrical Upgrade Project power system configuration.

The following components are affected:

1ASWGRUVLT1A1 1BSWGRUVLT1B1 1CSWGRUVLTIC1 1ASWGRUVLT1A2 1BSWGRUVLT182 1CSWGRUVLTIC2 1ASWGRUVLT1A3 1BSWGRUVLTIB3 1CSWGRUVLTIC3 2ASWGRUVLT2A1 2BSWGRUVLT2B1 2CSWGRUVLT2C1 2ASWGRUVLT2A2 2BSWGRUVLT2B2 2CSWGRUVLT2C2 h

2ASWGRUVLT2A3 2BSWGRUVLT2B3 2CSWGRUVLT2C3 2.0 DESIGN BASIS 2.1 The minimum allowable vital bus voltage is 94% (Ref.

6.2).

The undervoltage relay dropout setpoint should be above 94% with the sufficient margin to compensate a combined accuracy / repeatability error of the relays, potential transformers and testing equipment.

The dropout setpoint of 95.1 % will be considered in calculation.

The minimum value of a vital bus recovery voltage during the worst transient is above 97% (Ref.

6.2, 6.3 and 6.8). 'The 97% will be considered in calculation.

The undervoltage relay reset setpoint should be below the minimum bus recovery voltage.

The present technical specification time delay setpoint is 13 seconds and allowable value is 15 seconds (Ref.

6.5).

All voltage and time delay setpoints will be evaluated to determine if the accuracies resulting from using relays, pts and testing equipment are conservative, 2.2 It is required that the testing will be performed using i

j I

a Digital Fluke model #8600A or equivalent.

This model has an accuracy of 0.2% at 60 hz.

3.1 The ambient temperature range inside the associated cubicle will be between 65*F and 125 F.

Reference CBD states that the ambient room temperature is between 65 F and 105 F (Ref. 6.7).

3.2 Since the dropout (trip setpoint) is set as a percent of pickup (reset setpoint), it is assumed that both settings drift 61rectly proportional to each other.

3.3 A 3o (3 Sigma) accuracy can be assumed on accuracies given in the instruction

manual, per telecon with manufacturer.

Allowable " LOOP" Trip

= 111.934 VAC(94.17%)

which is greater than the minimum allowable bus voltage of 111.726 VAC (94%), therefore the UV relay setpoint of 113.0 VAC (95.1%) is acceptable.

y 4.5.1 Allowable Value (Maximum expected Trip Calibration Error)

The Allowable value for the Trip Setpoint considers only the part of the loop tested during surveillances (Relay and Test instrument). The calculated allowable value is the minimum voltage e

that ensures the relay would have functioned at or above the 94% setpoint.

Allowable value (AV) = Calculated Trip Setpoint (CSP) - Testing Inaccuracy (TI). CSP is the difference between the Analytical Limit and the Total Loop Accuracy (TLA). In this case, the limit not to be exceeded is a process limit (PL) which is the Minimum Bus Voltage ( 111.726 VAC or 94% )

and TLA is 0.566 VAC (s;ection 4.4.1).

CSP = PL + TLA 111.726 + 0.566

AV

= CSP - TI (r- ).

Reset Setpoint = Trip setpoint/99.1%

= 113. 0/ (O. 991)

= 114.026 VAC Actual Roset Setpoint = 114.1 VAC (96.0 %)

(Calibration Tolerance: 113.6 to 114.6 VAC )

INTRODUCTION These instructions contain the information required to properly install. operate, and test certain single-enase undervoltage relays type 27N. catalog series 2111 and 411T; and overvoltage relays, type 59N, catalog series 211U and 411U.

Tne relay is housed in a case suitable for conventional semiflush panel mounting.

All connections to the relay are mace at the rear of the case and are clearly numbered.

Relays of the 411T. and 411U catalog series are similar to relays of the 2117 and 2110 series.

Both sortos provide the same bastG tunct?ons and are of totally drawout construction; however, the 4117 and 4810 sectos relays provide integral test factitties.

Also, seguenced d1SCOnnects on the 410 series prevent nutsance operation during withdrawal or insertion of the relay if the normally.open contacts are used in the application.

Basic settings are made on the front panel of the relay, bonind a removable clear clastic cover.

Additional adjustment is provided by means of calibration potentto-metere inside the relay on the circuit board.

The target is reset by means of a pushbutton extending through the relay cover.

PRECAUTIONS (A

The following precautions should be taken when applying these relays:

1 Incorrect wiring may result in damage.

Se sure wiring agrees uith the connection diagram for the particular relay before energizing.

2.

Apply only the rated control voltage marked on the' relay front panel.

The proper polarity must be observed when the de control power connections are made.

3. For relays with dual-rated control voltage, withdraw the relay from the 1

case and j

check that the movable link on the printed circuit board is in the correct position for the system control voltage.

4 High voltage insulation tests are not recomunended.

See the section on testing i

for additional information.

5.

The entire circuit assembly of the relay is removable.

The unit should insert secothly. Do not use excessive force.

i

6. Follow test instructions to verify that the relay is in proper working order.

CAUTIGN: aince troubleshooting entsiis working nith energigod eeuioment, care shouid be. taken to eveld personel shock.

Only coneetant technicione familiar with good safety practices should service these devices.

PLACING THE RELAY INTO SERVICE

1. RECEIVING, MANDLING, STORA4E Upon receipt of the relay (when not included as part of a swi tchboa;'d ) examine for O

notify shipping damege.

If damage or Ioes te evident, file a claim at once and proostly Asea Brown Boveri.

An accurate peak detector is used in the types 27N and SDN.

Harmonic distortion in the 4C waveform can have a noticible effect on the relay operating point and on measuring instrumenta used to set the relay.

An internal hermonte filter is available as an option The harmonic filter attenuates all harmonics of the 50/40 Nr. input.for those apol tcations wher The relay then bestcally operates on tne fundamental component of the input voltage signal.

The essemely is identified by the catalog number stamped on the front panel i

and a sertal number stamped on the bottom of the circuit board.

Test connections are readily made to the drawout relay unit by using standard benana plug leads at the rear vertical circutt board.

This rear board is marked for easier identification of the connection points.

faportant: these relays have an external restator mounted on rear terminals t and g.

In order to test the drawout unit an soutvilent resister must be connected to l

terminals 1

& 9 on the rear vertical circutt board of the drewout unit.

The resistance value must be ?.he same as the resistor used on the relay. A 28 or 50 watt resistor wi1*

be sufficiant for testing.

If no resistor is available, the resistor assemely mounted on the relay case could be removed and used.

If the res is ter front the case is used, be sure to remount it on the case at the conclusion of testing.

Test Plug:

O value is based on the direction provided in ISA-sR6 Draft 10 of the Recommended Practice " Methodologies for the Determination of Satpoints for Nuclear Safety-Related Instrumentation".

Calculations, DE-TS.ZZ-1001(Q)Our technical standard for Instrument setpoin incorporate this direction.

is currently being revised to The recommended practice states that "The allowance between the allowable value and.the trip setpoint should contain that portion of the instrument channel being tested for the surveillance interval (monthly, quarterly, or refueling) no more than:

and should account for drift (based on surveillance interval)

Instrument calibration uncertainties for the portion of the instrument channel tested and

... instrument uncertainties during normal operation that are measured during testing.

The method adopted is to first subtract the Total Loop Accuracy (TLA) from the Analytical limit (AL) to ensure margin between the Analytical Limit and the setpeint.

and TLA is a fictitious number called the calculated setpointThe difference be (CSP).

The instrument uncertainties as discueeed above should O

O 34 37 CD 7.4.1.7-7 VOLTAGE RELAYS PACE 2 INTRODUCTION The ITE-27N and ITE-59N are companion high accuracy under and overvoltege relsys respectively.

Basic information on application and testing is in-cluded in IB 7.4.1.7-7.

This publication describes only the operation of the relay circuitry.

For the purpose of the following discussion PICKUP is defined as the high input voltage condition and DROPOUT as the low voltage condition.

For the ITE-27N Undervoltage Relay, PICKUF is the normal or reset condition and DROPOUT is the trip condition.

For the ITE-59N Overvoltage Relay, PICKUP is the trip condition and DROPOUT is the normal or reset condition.

POWER SUPPLY AND REFERENCE The relay's power supply is derived from the DC controi power input (ter-minals 7-8).

RV2, b,1un coil BT1 and C13 provide transient protection.

O Voltage selector plug VSP sets the dropping resistors for either a 48 or 125VDC supply.

Zoner diodes VR1, VR2 provide +/-15VDC voltages for the circuitry.

Integrated circuit U4 provides a highty stable 10 volt re fer-for the voltage measuring circuit.

ence l

INPUT CIRCUIT Transformer T1 reduces the 120V nominal input signal by a 10:1 ratio.

The gain of operational amplifier U1 is adjusted by the FICKUP tap selection

( R3 th ru R8 ).

The gain is set to give a 10 volt peak signal when the input voltage to the relay equals the pickup tap voltage selected. Calibration potentioaster R27 provides additional gain adjustment to allow the relay to be calibrated for any voltage between the fined tap settings.

FICKUF CIRCUIT U2 is an operational amplifier used open loop as a compariter. The 10V reference is applied through R10 to pin 3 of U2.

When the peak AC stenal on pin 2 exceeds 10 volts (input voltage above pickup) a negative pulse is obtained on output pia 6.

Resister R11 provides some positive feed-back to streteh the pulse. The negative signal is filtered by especiter C9 and applied to U3 pia 2.

A negative input on U3-2 easses the U3 out-O put to go high. 1.ID tedicator Dg1 is off.

Ftf Q1 is la the eseducting state. The selected dropout tap resistor (117-R20) causes the referosee voltage at pia 3 of 02 to be lower than 10V.

Calibration resister att provides additional adjustment between tape. This is the dropoet vettage reference value.

ATTACHMENT #5 3f 37 S-C-hV-J DC-959 Page g of A8'"

VOLTACE FILAYS CD 7 4 1.7-7 PACE 3 The dropout condition is reached when the input viltage to the retay drop such that the peak voltage at U2-2 is below the r eference voltage.

U2-6 then goes high, output Output U3-6 goes low.

LED D31 turns on.

F3T QL turns off. re establishing 10 volts as the re ference at U2-3 (pickup voltage ref-erence value).

TIMING CIRCUIT

'(Not Used on ITE-27N Instantaneous Models)

The output of timer IC 05, pin 3. is normally high.

When the output pin UJ-6 goes low (dropout condition), a trigger puise is applied through C19 to US pin 2.

Capacitor C20 is then allowed to charge through the selected time delay tap resistor (R63-R48).

When the volenge on C20 reaches a threshold vlaue. U5 output pin 3 goes low.

to provide for timing calibration.

R41 adjusts the threshold value When the input voltage to the relay returns above pickup, QS turns on, causing U5 to be immediately reset and its output to return high.

OUTPUT AND TARCET CIRCUIT!,

O For the output relay to be energized, the signal through D6 from the pickup circuit and the signal through D12 from the timer must be low.

This allows 03 to turn on, then Q2 to turn en energizing the :oit of output relay Kl.

At the same time. Q4 is energized to discharge Cl.l through the target thus changing the target status to orange.

(On ese ITE-27N with instan-

coil, taneous timing, the timing circuitry is not used to the output responds directly to the signal from U3-6.)

ITE-59N The operation of the ITI-59N relay is almost identical' to that of the ITE-27N.

The difference being that op amp U3 La changed to a dual type, with the U3-8 section used to invert the logic, so that a high voltage condition causes the LED to light, the timer to run, and the outpu: circuit to operate.

KARMONIC FILTER For applicatiets where waveform distortion would lie significant, a harmonic filter may be added. This filter preserves the 30 or 60M: content of the input signal.

(It does not determine the RMS value of the signal.)

The filter is inserted between U1 and U2.

(19 is reseved.) The gain of the filter is adjusted to 1.0 so that the basic e.ilibration of the relay f-(

is retained.
