JC-QlP81-90024 REV. 0031.0 PURPOSE AND DESCRIPTION1.1 The purpose of this calculation is to validate the Technical Specification AllowableValue and TRM Nominal Trip Setpoint for the 4160 V Division III Degraded BusVoltage trip function.1.2 The incoming breakers for the Div. III switchgear are automatically tripped on adegraded bus voltage condition after a time delay. The degraded bus voltage conditionis detected by sensors employing a one-out-of-two-twice logic. An undervoltagebetween 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 forthe preferred power source (offsite power) to recover. This time delay duration isdependent 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 andtime delays are derived from the station specific load flow and voltage dropcalculation (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 HPCSMotor 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 andoperate required Class 1 E loads under accident conditions with degraded voltagelevels present on the distribution system. Voltage sensing is performed by potentialtransformers located within the 4160 V switchgear for the division, and each potentialtransformer has a 4200 V/ 120V ratio. The HPCS system is designed to start andaccelerate the HPCS Pump with 75% of 4000 V motor voltage (3000 V), per NEDO10905-1. 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 torated current of the motor @ 434 A. Per PC 741-S-1404, the maximum power pointfor the HPCS Pump is less than 3100 Hp. At this operating point, the efficiency is0.935, and the Power Factor is 0.93, per Curve #455HA549. Therefore, at themaximum power point, with the motor drawing 434 A, the terminal voltage at themotor would be 3538 V. Per EC-QI 111-90028, the voltage drop is veryconservatively calculated to be 5.41 V. This places the 4160 V bus at 3543.41 V for asustained undervoltage condition limit. This correlates to a voltage of 101.24 V on a120 V basis, and is the lower analytic limit (Reference 2.27).The upper analytic limit for the voltage sensors is based on prevention of unnecessaryseparation of the Class I E buses, under anticipated minimum voltage conditions of theoffsite sources. Entergy System Planning Services performed, "Report on theAnalysis of Potential for Sustained Degraded Voltage on the Off-Site Electric Grid atthe Grand Gulf Nuclear Power Plant", dated November 9, 1990. This report providedthe expected grid performance of the GGNS Offsite Sources under severe

• CALCULATION SHEET_ ENTERGY "SHEET 7 OF 37CALCULATION NO. JC-Q1P81-90024 REV. 003contingencies. The results of this study determined that the 500 KV switchyardvoltage could be as low as 0.994 Per-Unit, and the 115 KV switchyard voltage couldbe as low as 0.976 Per-Unit.Calculation EC-QI 111-90028, then conservatively analyzed the Class I E loads withthe 500kV Offsite source at 0.975 Per-Unit and the 115kV Offsite source at 0.9675Per-Unit. It was determined that the Class 1 E system required loads would beadequately supported with 0.975 Per-Unit switchyard voltage available for the 500kVsystem and 0.9675 Per-Unit for the 115kV system. Therefore, it is appropriate that theupper analytic limit for the degraded voltage setpoint determinations be based on thecorresponding voltage available at the respective 4160 V Class IE buses, with 0.975Per-Unit 500kV system driving voltage or 0.9675 Per-Unit 115kV system drivingvoltage in each switchyard, under accident conditions. The lowest available transientvoltage on the Division III 4160 V bus under these conditions has been calculated tobe 3359.2 V, which occurs during the start of the HPCS pump, with bus voltagerecovery to 3880.9 V within 5 seconds. This condition provides an initial terminalvoltage at the HPCS pump motor of 3329.25 V, with voltage increasing as the motoraccelerates. The second lowest transient voltage step is 3846.34 V, with bus voltagerecovery to 3904.16 V, within 5 seconds. This interval is after the HPCS pump motoris already started, therefore the acceleration time of this load is not a factor. All otherbus voltage steps are calculated to remain above 3880.9 V. The recovery voltagesreferenced include the start demand of the next sequence interval, therefore actualrecovery voltages at the end of each step following load acceleration and prior to thenext sequence would be above thesevalues. Therefore, if the HPCS motor canaccelerate its load at the minimum transient voltage within the allowable time delayband, the recovery voltage predicted would form the upper analytic limit for degradedvoltage considerations during the sequence when the HPCS pump motor starts. For allsuccessive intervals, using the lowest available bus voltage step will ensure that otherequipment sequencing will not inadvertently actuate the Division III bus degradedvoltage sensors. As stated above, this correlates to a bus voltage of 3846.34 V. Thisvalue would bound all required conditions for the HPCS system to remain connectedto offsite power, without prematurely separating from this source, provided that thetime delay is set sufficiently to account for HPCS motor start time. Therefore, theoverall bounding upper analytic limit is 3846.34 V (109.89 V on a 120 V basis), andthe appropriate sensor time delay interval will also be based on this value (Reference2.27).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 activewhen a safety injection signal is present for Division III.The lower analytic limit for the safety injection condition time delay is based onproviding the capability to successfully start the HPCS pump at the lower analyticlimit of the degraded voltage sensors without segregating from the offsite source. Thisrequires that the time delay be of sufficient duration to allow for acceleration of the A CALCULATION SHEETENTERGYSHEET 8 OF 37CALCULATION NO. JC-Q1P81-90024 REV. 003HPCS pump motor under these conditions. Using the previously established minimumHPCS motor starting voltage available from a viable offsite source of 3329.25 V, theacceleration time for the HPCS pump motor has been determined to be no more than3.28 Seconds. This condition conservatively bounds the acceleration time required atthe lower analytic limit bus voltage of 3543.41 V. Therefore, 3.28 seconds is thelower analytic limit for the safety injection condition degraded voltage time delay.The upper analytic limit for the safety injection condition degraded voltage time delayis derived from the required time response for the HPCS system to achieve necessaryinjection flow within 27 Seconds of accident initiation. This further requires that theHPCS system be connected to a viable power source within 10 seconds to achieve thisgoal. The limiting case for this upper limit is when offsite power is available butdegraded (i.e, above the Loss of Voltage settings, but below the lower analytic limitfor the degraded voltage sensors), with an accident signal present. This is because thedegraded voltage function trips the incoming source only, therefore requiring thesubsequent sensing and time delay from the Loss of Voltage function to connect theEmergency Diesel Generator (EDG) to the bus. The EDG receives a separate safetyinjection signal, so the EDG start time and the total voltage sensing sequencedescribed will occur concurrently. This limits the allowed combined sense and actuatetimes for the degraded voltage and loss of voltage functions to no more than 10seconds total. It is desirable that the degraded voltage time delay be of a longerduration 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 timedelay. Correspondingly, a 4 Second upper analytic bound is thus established for theloss of voltage time delay by this selection.The design for the Division III Degraded Voltage detection was provided by GE underFDDR 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 wasperformed to justify the nominal 5 minute degraded voltage time delay, no LOCAsetpoint (MPGE-86/03 1). The actual evaluation resides with GE, and was notprovided to GGNS. This evaluation was based on nominal setpoint values, with noapparent consideration for uncertainties.GE did not provide a Design Specification Data Sheet for the Degraded voltagefunction, possibly due to the unique application, i.e., the function did not meet theconventional "instrument loop" configuration. Because no Design Specification DataSheet was generated, no definitive Analytic Limit determinations were provided toGGNS.The appropriate method to determine an upper Analytic Limit for this parameter is todetermine a minimum that the bus voltage could degrade to, and evaluate themaximum permissible time that the system could sustain this voltage without causingequipment damage or loss of function due to protective device actuations, such as SHEET 9 OFREV.CALCULATION NO. JC-O1P81-90024circuit breaker or thermal protection trips. This is to ensure that the system willmaintain the capability to automatically respond to a subsequent LOCA signal,without incurring functional impairment due to the offsite source degradation. Whilethe capability to provide uninterrupted functional capability due to offsite sourcedegradation has been a relevant consideration from original system design, theinherent historical assumption has been to consider the level of degradation that wouldbe expected, and assume a loss of the offsite source completely below that point. Thisalmost certainly formed the basis for the original system settings. During theElectrical Distribution. System Functional Inspections performed by the NRC in theearly 1990's, certain utilities received questions relating to system performance if thevoltage theoretically degraded below this level, but remained above the loss of voltagesetpoint. Apparently, the transmission systems for some plants may have beenmarginally configured such that voltage degradation to sustainable values at thetransmission system level could represent an extremely degraded value in the plantSwitchyard. This consideration is further discussed as it relates to GGNS.For GGNS, the existing time delay settings are acceptable, provided that the degradedvoltage remains sufficiently high to start the HPCS loads. This correlates to a motorterminal voltage of 75% of the motor base voltage for HPCS system motors. Reviewof calculation EC-Q 1111-90028, has determined that the bounding percent voltagedrop 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 conservativelyassumed 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 than73% of rated bus voltage (4160 V). Therefore, the HPCS pump motor would beexpected to start for offsite source degraded voltage conditions down to 88% of ratedoffsite source voltage (73% + 15% = 88%). The remaining consideration forcontinued relay timing limitations would be the motor heating limits once the motorhas started. Motor heating must be limited to that imposed by curve #455HA550. PerPC 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 themotor, 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 of600 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 atleast 88% of rated.A discussion of the practical operating limits for the Entergy Transmission system andsystem generators, provides confirmation of the adequacy of this anticipateddegradation level. The Entergy Transmission Planning Guidelines impose therequirement that substation bus voltage capabilities be maintained at no less than 92%of rated, even under severe contingency analysis conditions. In fact, this represents anextreme case for system voltage level degradation limits, because the generation CALCULATION SHEET__ ENTERGYSHEET 10 OF 37CALCULATION NO. JC-QlP81-90024 REV. 003facilities generally are forced to reduce generation (including reactive generation forvoltage support) at about 95% of rated voltage, to protect individual generators fromthermal damage due to over-excitation. In the case of severe sustained degradedvoltage conditions, this would almost certainly lead to load isolation or system voltagecollapse. In either case, loss of the offsite source or system voltage recovery toacceptable levels for continued generation would be an expected consequence in veryshort order. Additionally, GGNS is located within the system such that transmissionsystem voltage levels very closely match generation station Switchyard outputvoltages. GGNS 500 KV Switchyard nominal voltage is 1.02 PU. Thus anydegradation seen in the GGNS Switchyard would also be seen by the supportinggeneration. Therefore, sustained degraded grid conditions below about 95% would notbe expected to occur for GGNS, and System Planning Analyses ensure the capabilityto maintain at least 92% Substation voltage under severe contingency considerations.With these considerations, it would be appropriate to select 600 seconds (10 min.) asthe upper analytic limit for the Division III Time Delay, No LOCA. For additionalconservatism, this limit will be set at 360 seconds (6 min.). This provides adequatetime for voltage recovery to above the degraded voltage set-point, while ensuring thecontinued automatic availability of the system, should a subsequent LOCA signal bereceived. The lower analytic limit for this parameter should be based on a reasonableperiod to allow time for recovery. It is to be selected to provide an equivalent marginfrom the nominal trip setpoint as the margin allowed from the setpoint to the upperanalytic limit (i.e. I min.). Therefore, the lower analytic limit for the Time Delay, NoLOCA is 4 minutes.1.5 The design consideration for the subject instrumentation is: Degraded Grid Voltage1.6 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 forcombining statistically independent uncertainty components.

NCALCULATION SHEET__ ENTERGYSHEET 32 OF 37CALCULATION NO. JC-QIP81-90024 REV. 003As stated previously, with 0.975 Per-Unit switchyard driving voltage, the lowesttransient 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, withvoltage recovery to 3880.9 V (1 10.88V on a 120V basis). This condition provides aninitial terminal voltage at the HPCS pump motor of 3329.25 V. Assuming a constantterminal voltage of 3329.25 V (i.e. no voltage recovery as the motor accelerates) theacceleration time of the HPCS pump motor has been determined to be no more than3.28 seconds. Therefore, the actual recovery time to at least 3880.9 V would be nomore 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 thedropout (trip) point is established by the 99% tap setting at 104.60V. Assuming worstcase performance of the relays, the trip could occur at the Upper Allowable Value of107.53 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 relay108.60 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 valuewill prevent spurious segregation from the preferred off site source and is acceptable.7.0 TSTF CALCULATIONS (Ref. 2.1)7.1 As-Left ToleranceALTv -Undervoltage Relay (Voltage Trip) TSTF-493 CalculationALTv = RAv= +0.21VALTT -Undervoltage Relay (Time Delay) TSTF-493 CalculationALTT = RAT= +/- 0.40 secondsALTTD -Time Delay Relay TSTF-493 CalculationALTD = RATD= +/- 15.0 seconds7.2 As-Found Tolerance (AFT)The drift values used in this calculation were derived by statisticalanalysis, therefore per Reference 2. 1:

I-T-E SOLID STATE VOLTAGE RELAYS PAGE.-PAGE 9TESTING1. MAINTENANCE AND RENEWAL PARTSNo routine maintenance is required on these relays. Follow test Instructions to verifythat the relay is in proper working order. Ve recommend that an inoperative relay be returnedto the factory for repair; however, a circuit description and/or a schematic diagram areavailable for those who wish to attempt repairs. Contact your local sales engineer or contactthe factory. These relays have a control relay as the output stage. This output relay may beordered from the factory. Replacement target head assembly may be ordered should the targetbe mechanically damaged. (See page it)Also avallable from the factory are circuit card extenders which are recommended for usawhen calibrating the relays. All these relays use the 18 point extender, catalog 200XOOl8.OlAWOUT ELEMENTDrawout circuit boards of the same catalog number are Interchangeable. The board is reaovedby using the metal pull knobs on the front pIael. The circuit board is identified by thecatalog number on the front panel and a serial number stamped on the under side of the circuitboard.CAUTION A1TACH-MFN4TSimce troubleshooting entails working with energIzed equipment, caution XTOJcIeRF -7O should be taken to avoid personal shock. Only competent technicians PAGE C1 OF )familiar with good safety practices should service these devices.L. HIGM P0TNTIAL TEsDo not apply high potential tests to solid state relay circuits. 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 TESTSFollow 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 to110 percent of pickup. Tolerances should be within those listed on page S. Calibrationwy be trImmd or adjusted to the final settings required for the application at this time.CAUSUTN TESTSConnect the relay to the proper source of control voltag (to match the relay nameplaterating). for relays with dual rating, be sure the movable link an the circuit board is in thecorrect 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. Werecommend 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 conveniencein testing. its action is Instantaneous, thereby removing the uncertainty caused by the timedelay before the output contacts transfer. The action of the indicator depends an the voltagelevel 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 satat the nearest value to the desired setting. Decrease the voltage until dropout occurs, thenrecheck pickup by Increasing the voltage. ReadJust until pickup occurs at precisely the desiredvoltage.

18-7.A I.77PAGE 10OI-T-E SOLID STATE VOLTAGE RELAYSPotentiometer R16 is provided to adjust dropout. Set the dropout tap to the next lowertap to the desired value. Increase the input voltage to above pickup and then lower untildropout 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 thetime-voltage curves by means of the time delay calibration potentiometer R41. Time delay isinitiated 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 delayperiod, the output contacts will transfer.The locations of the calibration potentliomters are shown in fIgure 5. The potentiometersare multi-turn types for excellent resolution and ease of setting.BUILT-IN TEST FUNCTIONA built-in test function is provided for convenience in functlonally testing the relayand associated devices. CAUTION: tests should be made with the maim circuit de-energized. Iftests are to be made on an energized circuit, take all necessary precautions. The test buttonis labelled TRIP. For the ITE-27N, when the button is depressed, at undervoItage conditionis simulated, and the relay will operate. For the ITE-55N, an overvoltage condition issimulated.

2to JC-Q1P81-90024SECTION 1 SHEET 3 OF 17GENERAL INFORMATIONPURPOSEThe BEI-Z7 Undervoltage, BE1-59 Overvoltage and the BEI-27/5g Under/OvervoltageRelays are solid-state devices which provide reliable protection for generators,motors and transformers against adverse system voltage conditions.ApplicationElectric power systems are designed for constant voltage operation. Loadsutilizing commercial electric power are designed to operate at a constant inputvoltage level with some tolerance. Radical voltage variations on a power systemare indicative of a system malfunction. Protective relays which monitor systemvoltage and provide an output signal when the voltage goes outside predeter-mined limits, find a variety of applications. Some of these applicationsinclude motor, and transformer protection, interface protection for cogenerationsystems, and supervision of automatic transfer switching schemes.Motor ProtectionWhen selecting the type of protection for motor applications, the motor type,voltage rating, horsepower, thermal capability during start-up, and exposure toautomatic transfer restarting following a voltage interruption need to be con-sidered. During motor start-up, a low terminal voltage condition will inhibitthe motor from reaching rated speed. The 8E1-27 undervoltage relay will detectthis low voltage condition and trip. Critical applications requiring continuousmotor operation and applications where overloads during start-up may be main-tained for a given time period, usually have a definite time or inverse timedelay characteristic incorporated to avoid unnecessary tripping during lowvoltage dips. If the undervoltage condition persists for the established timedelay, the relay output contacts are connected to the station aarm annunciatorpanel, allowing the station operator to take corrective action. The BEl-59Overvoltage relay is applied to insure the voltage does not exceed the limitsestablished by the machine manufacturer for proper operation. Overvoltage con-ditions stress the insulation level of the equipment and may cause a dielectricbreakdown resulting in a flashover to ground.Automatic Transfer SwitchingDistribution substations are sometimes designed with duplicate supply circuitsand transformers to eliminate service interruptions due to faults located on theprimary feeder. In order to restore service within a given acceptable timeperiod, automatic transfer switching can be applied to initiate the throwoverfrom primary power to the alternate power source. The BE1-27 Undervoltage Relaycan initiate switching after a given time delay to void transfer switchingduring temporary low voltage conditions.

2Cogenerati on to JC-QIP81-90024SHEET 4 OF 17utilities employ the use of a voltage check scheme to supervise reclosing at thesubstation when cogenerators are connected to a radial distribution feeder andthe cogenerator is capable of supplying the entire load when the utility circuitbreaker Is open. During a faulted condition, the utility requires the cogenera-tor to be disconnected from the system before reclosing the utility breaker. Ifthe cogenerator is connected to the system, the utility will reclose to anenergized line.This could result in reconnecting two systems out of synchronism with eachother. A BE1-27 undervoltage relay monitoring the line voltage will inhibitreclosing 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 thecogenerator may become overloaded, the BE1.27 Undervoltage Relay will detect thedecline in voltage and remove the cogenerator from the system. The BE1-59Overvoltage Relay will protect the system from overvoltage conditions that occurwhen power factor correction capacitors are located on the feeder.Transformer ProtectionVoltage relays can be applied to protect large transformers from damage as aresult of overexcitation. The concern for transformer overvoltage may be mini-mized in many power system applications where proper voltage control of thegenerating unit is provided. However, where a tap changing regulating trans-former is located between the generating source and the load, some form ofvoltage protection may be required to supplement the tap changing control and toprevent equipment damage due to over, as well as undervoltages resulting from afailure of the tap changing control. The BE1-27/59 Under/Overvoltage Relay iswell suited for these applications.Ground Fault DetectionIn 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 notbe detected by the overcurrent relays. This condition, however, may be sensedby 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 asdescribed above, can be quickly detected and isolated.Y.iFigure 1-1. Ground Fault Detection1-2M.-.

It has twoshaded-pole U-magnet type driving elements actingon opposite sides of the disk. One of these, theoerating element, is designed to drive the disk ine direction to close the left contacts and theother, the restraining element to drive le disk Itthe contact-openingdirectionon relays having single-throw contacts and to close the right contacts onrelays having double-throw contacts. The diskshaft Is restrained by a spiral spring, the principalpurpose of which is to hold the contacts open whenthe relay is do-energized. The motion of the diskis retarded by permanent magnets to give thecorrect time delay for closing the contacts.There is a seal-in unit mounted to the left ofthe shaft on the Type IJF5IA and UFSIB relays.The Type IJF52A relay has a seal-in unit mountedon both sides of the shaft. This element has Itscoil in series and its contacts in parallel with themain contacts such that when the main contactsclose, the seal-in element picks up and seals In.When the seal-in element picks up it raises atarget Into view which latches up and remainsexposed until released by pressing a button beneaththe lower left corner of the cover.The case is suitable for either surface orsemaflush panel mounting and an assortment ofhardware is. provided for either mounting. Thecover attaches to the case and also carries thereset mechanism when one is required. Eachcover screw has provision for a sealing wire.The case has studs or screw connections atboth ends or at the bottom only for the externalconnections. The electrical connections betweenthe relay units and the case studs are madethrough spring backed contact fingers mounted instationary molded Inner and outer blocks betweenwhich nests a removable connecting plug whichcompletes the circuits. The outer blocks, attachedto the case, have the studs for the external con-nections, and the inner blocks have the terminalsfor the internal connections.The relay mechanism is mounted in a steelframework called the cradle and is a complete unitwith all leads being terminated at the inner block.This cradle is held firmly in the case with a latchat the top and the bottom and by a guide pin at theback of the case. The cases and cradles are soconstructed that the relay cannot be inserted in thecae upside down. The connecting plug, besidesmaking the electrical connections between the re-Te ctive blocks of the cradle and case, also locklatch In place. The cover which is fastened tothe case by thumbscrews, holds the connecting plugin place.To draw out the relay unit the cover is firstremoved, and the plug drawn out. Shorting bars areprovided in the case to short the current transformercircuits. The latches are then released, and therelay unit can be easily draw out. To replace therelay unit, the reverse order is followed.A separate testing plug can be inserted In placeof the connecting plug to test the relay in place onthe panel either from its own source of current andvoltage, or from other sources. Or, the relay unitcan be drawn out and replaced by another which hasbeen tested in the laboratory.APPLICATIONThe Type UJF frequency relay. are recom-mended for protection of synchronous apparatusagainst overapeed or underspeed conditions causedby loss of load In the case of generators, or loss ofsupply 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 frequencyof the circuit varies by a predetermined amountabove or below normal.RATINGSThese relays are available in frequency ratingfrom 25 to 60 cycles and voltage ratings of II and230 volts.The current closing rating of the contacts is30 amperes for voltages not exceeding 250 volts.The current-carrying ratings are afected by theselection of the tap on the seal-in coil as IndicatedIn Table LTABLE I7 1 Amperes, AC or DC,.t~n 2-Amp TaplO .2 Amp TapTripping Dutycarry continuously303$50.3-~ -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.
