Typical operating times are shown in Figure 15. Three PVD relays an. a lockout relay are required for combined phase and ground f ault protection of a three phase bus. Four models of the relay are available as listed in Table *. TABLE 1 VOLTAGE CURRENT NO. OF THYRITk UNIT (87L) UN'T (37H) STACKS h PVD21A Yes No-1 PVD218 Yes Yes 1 PVD21C Yes No 2 PVD21D Yes Yes 2 Thyrite;g PVD21C and PVD210 models of the relay include two paralleled voltage limitingDi stacks Tt ~ models. This feature makes the PVD21C and PVD210 models better suited to those applications where high internal f ault currents can be encountered. This is discussed in detail in the section on APPLICATION in this instruction book. The PVD21A and PVD218 models of the relay include a high speed overcurrent unit (87H) in addition to the voltage operated unit (87L). This unit may be used to supplement the high speed voltage unit, and/or when provided with a suitable external h timing device and auxiliaries,'it may be used to implement breaker f ailure protection. This is also disccused in detail in the APPLICATION section. The PVD relays are mounted in a single-end M1 size drawout case, and are provided with a single saal-in and separate targets for each unit. Outline and panel drilling dimensions for the relays are illustrated in Figure 1. Wernal connections for the various models are illustrated in Figures 2 and 3. @ Registered trademark of General Electric Co. 1 m.. s....... ...,.,,.,.. -,. n m a u.,,,..,.. s..,.u . ~, e-

~~ GEK-45405 The external connections for the PVD21A and PVD21C relays are illustrated in h Figure 4; those for the PVD218 and PVD210 relays are shown in Figure 5. APPLICATION Thc following comments on the applications of the Types PVD21A, PVD21B, PVD21C and PVD210 relays may be better appreciated if the detailed section on OPERATING PRINCIPLES is reviewed before proceeding. The Type PVD21 relays can be applied for bus protection in most cases where cts having negligible leakage reactance are used. This generally
- ncludes any kind of current transformer with a toroidal core if the windings (on the tap used) are completely distributed about the core.
The elementary diagram of the external connections for a typical applicaticn is shown in Figures 4 and 5. A bus differential scheme utilizing Type PVD relays has certain advantages that simplify application considerations: e Standard relaying-type bushing current transformers may be used e Performance for specific applications is subject to simple calculations e Protection is easily extended if the number of connections to the bus is increased. The following points must be considered before a particular application is d at tempted: All cts in the bus differential circuit should have the same ratio. When adding 0 to an existing bn, at least one CT in the new breaker should be ordered with the same ratio as the bus differential cts in the existing breakers. If the differential circu.; unavoidably includes different ratio cts, the application may still be possible, but special attention must be given to protect against overvoltage conditions during internal f aults. = If one or more of the cts in Figures 4 or 5 are a different ratio than the others, it would appear that the simple solution would be to use the full winding of the lower ratio cts and a matching tap on the higher ratio cts. The high peak voltages that occur during an internal f ault will be magnified by the autotransformer action of the tapped higher ratio cts, and the peak voltages across the full winding of the higher iatio cts may exceed the capability of the insulation in that circuit. Refer applications involving different -atio cts to the local General Electric Sales office. When all current transformers are of the same ratio, full windings, instead of g taps, should be used. This will insure maximum sensitivity to internal f aults in addition to limiting peak voltages, in any case, CT secondary leakage reactance must be negligible. It may be possible, although not desirable, to use the differential circuit cts ,icintly for other functions. The performance of the system under these conditons can be calculated by including the added burden as part of the CT lead resistance. 4 4
GEK-45405 s h However, consideration must be given to the hazaras of f alse operation due to extra connections and errors in testing the tdded devices. Note that the relays may trip if a CT secondary is open circuited during normal operation of the associated bus. Thyritehanon-linearresistance, is used in the relays to limit the voltages that can be ceveloped across the relay during an interna' f ault to safe values. The magnitude of the voltage that can be developed will be a function of the total internal f ault current and the encWristics of the cts used in the dif ferential circuit. Figure 9 illustrates the sf c application limits for the PVD21 A and PVD218 relays as a function of the total f ault current and the knee point voltage (Es, nf the poorest CT in Q the circuit, if the fault current and knee point voltage are such that the intersection of these two points plots below the curve, then the application will be safe with respect to the voltage limits. Note that t Qs curve applies for the PVD21A and PVD21B relays which have a single stack of ThyritW. If the application of these relays does not appear to be permissible on the basis of Figure 9, it may still be permisQble if the PVD21C or PVD210 relay is used. These relays have two stacks of Thyrit W connected in parallel so that significantly greater internal fault currents can be accomodated. Figure 10 may be used to determine the safe application limits for the PVD21C and PVD210 relays. low in the Th r'th stack, causing energy During an internel f ault, current will thermaf damage, a contact of tg to be dissipated. To protect the Thyrit from lockout relay must be connected as shown in Figures 4 and 5 t%@short out the ThyritW during an internal f ault. The thermal limits of the Thyrit ull not be exceeded provided the relay time, plus lockout relay time, is less than four cycles. An instantaneous overcurrent unit, 87H, is connected in series with the Thyrith in PVD218 and PVD210 models. The 87H unit, when set with the proper pickup, may be used to supplement the voltage unit, 87L, and/or implement breaker f ailure protection wh5n a suitable timing relay and other auxiiiary devices are prnvided by the user. ine required setting of the 87H unit is related to the actual setting of the 87L ur.it. Figure 8 illustrates the setting to be made on 87H as a function of the 87L setting. Thus, once the voltage unit setting has been calculated, the current unit setting is easily determined. Figure 5, which applies to the PVD218 and P)@21D relays, shows the contact of the lockout relay connected to short out the ThyritW only. However, the 87H unit is not shorted so that the relay can continue to operate as an overcurrent function, because it will stay picked tp until the f ault is cleared. The 87H unit may be used to 9 implement breaker f ailure protection. Device 62X can be connected as shown in Figure SA to initiate operation of the breaker failure timer. Tne curve of Figure 8, which illustrates the 87H setting as a function of the 87L setting, includes sufficient margin to insure that the overcurrent unit will not operate during an external f ault. For this reason, the 87H unit will be less sensitive than the 87L unit, and it may not operate for all internal f aults. However, it will pick up as soon as the lockout relay cperates, provided the f ault current is above the pickup setting, li, those cases where the 87H unit does not pick up until the lockout relay oprates, the dropout time of 87L is sufficient to overlap the pickup time of 87H, so that a continuous input will be provided to device 62X. 9 5 m. )

The external connection diagrams of Figures 4 ann 5 indicate that the differential points for the relays are located in the switchyard. For outdoor installations where there is a great di:tance between the breaker and the relay panel, junction it may be desirable to locate the differential junction in the switchyard, since the resistance of the f ault CT loop may otherwise be too large (refer to the section, Note that the cable resistance from the junction point to CALCULATION OF SETTJMGS). It is permissible to the relay is not included as part of tne f ault CT loop resistance. locate junction points at the panel, providing that the resulting relay setting gives the desired sensitivity. T:.e 87L unit should be set no higher than 0.67 times the secondary excitation voltage at ten amperes secondary excitation current (evaluated for the poorest CT in the differential circuit). When circuit breakers cre to be bypassed for maintenance purposes, ur when any other atypical setup is to be made, other means than simply opening the PVD contact circuit should be used to avoid incorrect tripping. Voltages.that axceed the continuous rating of the PvD may be developed with the high impedance operating coil This can be avoided by removing the g still connected in the differential circuit. connection plug, or if external means are required, by short circuiting studs 4 and 5 to stud 6. The follcwing information must be obtained before settings are determined for a particular application: e Determine the secondary winding resistance for all the cts involved e Obtain the secondary excitation curves for all the cts involved e Determine the resistance of the cable leads from the cts to the differential junction point. CONSTRUCTION The Type PVD relays are assembled in the medium size single-end (M1) drawout case g having studs at one end in the rear for external connections. The electrical connections between the relay and case studs are through stationary molded inner and outer blocks, between which nests a removable connecting plug. The inner block has the terminalt for the internal connections. Every circuit in the drawout case has an auxiliary brush, a; shown in Figure 13, Some ( to provide adequate overlap when the connecting plug is withdrawn or inserted. circuits are equipped with shorting bars (see internal connections, Figures 2 and ), and it is especially important that the auxiliary brush make contact on those circuits with adequate pressu e to prevent the opening of important interlocking circuits, as a E indicated in Figure 13. 6 ) j
GEK-45405 () The relay mechanism is mounted in a steel f ramework called the cradle and is a complete unit with all leads terminated at the inner block. This cradle is held firmly in the case with a latch at both top and bottom and by c guide pin at the back of the case. The connecting plug, besides making the electrical connections between the respective blacks of the cradie and case, also locks the lt.ch in place. The cover, t which is drawn to the case by thumbscrews, holds the connecting plugs in place. The target reset mechanism is a part of the cover assembly, The relay case is suitable for either semiflush or surf ace mounting on all panels i up to two inches thick, and appropriate hardware is available; however, panel thickness (]) must be indicated on the relay order to insure that the proper hardware will be included. Outline and carel drilling dimensions are shown in Figure 1. 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. The relay also can be drawn out and replaced by aro+.her which has been tested in the laboratory. The relays covered by these instructions include two hinged armature type operating units: a " low-set" voltage unit, device 87L, and a "high-set" current unit, device 87H. Device 87L is an instantaneous telephone-type voltage unit having its coil connected across the DC terminal of a f ull wave rectifier. In turn, the rectifier is connected to a high pass filter through an attenuator network. The 87L unit has two normally open contacts. One set of contacts is connected between terminals 7 and 8, and the other set is connected in parallel w La the contacts of the seal-in unit. t Device 87H is an instantaneous *overcurrent unit,Rounted in the upper right hand corner, with its coil connected in series with ThyritW resistar discs. A single set a of normally open contacts is connected between tenninals 9 and 10. L Hi-Seismic Seal-in Unit A seal-in unit is mounted in the upper lef t corner of the relay (see Figure 3). The unit has its coil in series and its contacts in parallel with a set of normally open contacts of the 87L unit. When the seal-in unit picks up, it raises a target into view. The target latches up and renains exposed until it is released by manual operation of the reset button, which is located at the lower left e.orner of the relay. 8 RANGES These relays are available for 60 hertz.

There will always be at least one ampere overlap between the maximum L setting and the minimum H setting. Select the higher range whenever possible, since it has the higher continuous rating. 9 For other ranges, consult the local General Electric Sales Office. 87L Continuous Rating The voltage circuit included in the 87L unit has a continuous voltage rating if 150 volts RMS, Refer to the ACCEPTANCE TESTS section for precautions that should be taken during testing. Contacts The current closing rating of the contacts is 30 amperes for voltages not exceeding 150 volts. The current carrying rating is limited by the seal-in unit rating. H,I-SEISMIC TARGET AND SEAL-IN UNIT The Type PVO relay is provided with a universal target and seal-in unit having 0.2 and 2.0 ampere taps as indicated in the following tabulations. If the tripping current exceeds 30 amperes, an auxiliary relay should be used.

The relays are also provided with either one or two Thyriteu stacks (see Table 1) connected in parallel with the 87L unit to limit the voltage across tM relay to safe values during internal f aults. In limiting the voltage, the Thyrit@ will pass sigt.ificant current during internal f aults, but very little current duriy normal operating conoitions or external f aults. The PVD218 and PVD210 relays are g provideg with an instantaneous overcurrent unit (87H) connected in series with the Thyrit 6tV. The 87H unit is set so that it will not operate for the maximum external s f ault, but will operate for heavy internal f aults. The diagrams of Figures 4 and 5 illustrate typical external connections to the relays for use in a bus differential scheme. A conventic.41 differential circuit is utilized, that is, the cts associated with all of the circuits off the bus are connected in wye and paralleled on a per-phase basis. One PVD relay per phase is required to provide complete protection for the bus. VOLTAGE UNIT (87L) - PVD21A, PVD218, PVD21C. PVD21D If a protection scheme utilizing c PVD rclay is to perform satisf actorily, it must not trip for f aults external to the zone of protection, such as at 'F1 in Figure 6. Since the PVD relay is a high impedance device, consider the effect of an external g single line to ground fault. Figure 6 illustrates this condition for the f aulted phase only. Each of the cts associated with an infeeding circuit will produce the secondary voltage recessary to drive its secondary current through its winding and leads. The CT in the f aulted circuit will produce the voltage necessary to drive the total secondary f ault current through its winding and leads. If ali of the cts were to perform ideally, there would be negligible voltage developed across Junction points A and D, and hence across the PVD relay. Incidentally, load flow across the bus is similar in effect to an external f ault, a there will also be little voltage developed across the. relay during normal operating conditions. Unfortunately, during f aelt conditions cts do not always ., perform ideally, because core saturation can cause a breakdown in CT ratio. Such core D saturation is generally accentuated by DC transients in the primary current. Any residual flux left in the core may also add to the tendency to saturate. 9
~ 6 GEK-45405 In the example of Figure 6, the worst condition would be realized if the CT h associated with the f aulted circuit saturated completely, thus losinc its ability to produce a secondary voltage, while the other cts aid not Saturate at all. When a CT saturates completely, its secondary impedance approaches the secondary winding resistance, provided the secondary leakage reactance is negligible. This will be the case when cts wound on a toroidal core with completely distributed windings are used. The CT', in the infeeding circuits would then be unassisted by the f ault CT and would have to produce enough voltage to force their secondary currents through their own windings and leads, as well as the windings and leads of the CT associated with the faulted circuit. As a result, a voltage will be developed across the junction points, A and D, and hence across tne PVD relay. The magnitude of this voltage will simply to equal to the product of the total resistance in the CT loop circuit and the total f ault current in secordary amperes, that is, VR * (Rs + 2R ) (1) L where: VR = voltage across PVD relay Rs = CT secondary winding and lead resistance RL = one way cable resistance from junction point to CT IF = RMS value of primary fault current N = CT ratio Note that the f actor of two, appearing with the RL term, is used to account for the f act that all of the f ault current will flow through both tha outgoing cable and the return cable for single line to ground faults. If t;e cts e e connected as shown in g Figures 4 or 5, no current will flow in the return lead for three phase f aults, thus the maximum voltage developed across the PVD relays for three phase f aults can be calculated as follows: IF Vp = (R$+R) (2) L N Equations (1) and (2) can be consolidated and written as follows: I R = (Rs + PR ) - F (3) V L N where: P = 1 for three ph?se f aults, and 2 for single line to ground f aults. For the conditions in gev tion, this voltage, V, is the maximum voltage that g R could possibly be developed across the PVD relay. Obviously, the CT in the faulted circuit will not lose all of its ability to produce an assisting voltage, ar.d the cts in the infeeding circuits may tend to saturate to some degree. In practice, the voltage developed across the relay will be something less than that calculated from equation (3) above. The effect of CT saturation is accounted for by the CT performance f actor. K, used in the equation for calculating the actual voltage setting, and it is discussed f urther in the section CALCULATION OF SETTINGS. Now consider the effect of an internal f ault. In this case, all of the infeeding cts will be operating into the high impedence PVD in parallel with any idle cts. The g voltage developed across the junction points A and 0 will now approach the open circuit 10
GEK-65405 h secondary voltage that the cts can prod"ce. Even for a moderate internal f ault, this voltage will be in excess of the value calculated for the maximum external f ault as described above. Theref ore, the high impedance voltage rensing unit, 87L, can be set with a pickup setting high enough so that it will not operate as the result of the i maximum external f ault, but will still pick up for moderate and even slight internal faults. Consequently, the relay will be selective between internal f aults ant, external f aults or load flow. ] 4 The actual ecuation for calculcting the 87L voltage unit setting, taking CT performance and margin into account, is as f ollows: h IF (4) R = (K) (1.6) (Rs + PR ) 7 V L where: K = CT performance f actor (see Figure 7) 1.6 = margin f actor All other terms are as described above. OVERCURRENT UNIT [87H) - PVD21B, PVD21D_ The PVD21B and PVD210 relays arc similar to the PVD21A and PVD21C
- lays, respectively, except for the addition of the 87H unit in series with the Thyri The 87H unit is set so that it will not operate on the current passed by the Thyrit during external faults, but so that it will operate on the current passed during heavy g
internal faults. During normal operating conditions, there will be little voltag developed across the PVD relay, and hence across the series combinstion of the Thyrit6tv and 87H. During external f aults, the same would be true if the cts did not saturate. Even if the CT in the f ault circuit saturated completely, the maximm voltage that could be developed across the relay would be limited to the drop in the CT resistance plus the associated cable resistance. Because 87L is set at some value above ge maximurn expected drop, it is possible to determine the current through the Thyriteu at the 87L setting, and so determine a suitable setting for 87H to insure that it does not operate for the maximum external fault. Figure 8 illustrates the minimum safe pickup setting to be made as a function of the 87L setting with suitable marcin included. Thus, once the 87L setting has been calculated, the 87d setting can be ec.sily determined from Figure 8. During internal f aults, the cts will attempt to drive all of the f ault current g through the high impedance PVD relay. As a result, the voltage will build u gquite rapidly across the relay. As the voltage builds up, the nonlinear Thyriteu will exhibit a declinirgresistance characteristic, so that significant current will flow through the ThyritW and so cause 87H to operate. Because of the margin involved in setting the 87H unit, it will not be quite as sensitive as the 87L unit and it may not operate for some Icw level f aults. It is not possible i.o predict at exactly what f ault level the 87H unit will operate because of the numerous f actors involved. However, 87H still may be used to supplement tripping by 87L with the assurance that it will at least operate for heavy internal faults. The 87H unit may also be used to implement breaker f ailure protection, as described in the APPLICATION section. h 11

The cir:uits wili i resulting IR drop will be the maximum possible voltege which can appear across the PVD relay f or that external fault.

GEK-45405 g* The value of the 87L unit setting established by equation (5) is the minimum safe settino. Higher settings will provide more safety margin, but will result in somewhat reduced sensitivity. The methods of utilizing equation (5) are outlined below: Method I - Exact Method: (1) Determine the maximum three phase and single phase to ground f ault currents for f aults just beyond each of the breakers. (2) The value RL is the one way cable DC resistance from the junction point to the faulted CT being considered. (3) For each breaker in turn, calculate VR separately utilizing the associated maximum external three phase f ault current, with P = 1, and the maximum external single phase to ground fault current, with P = 2. (4) Use the hignest of the values of VR obtained in (3) above. Method II - Simplifieri Conservative Method: (1) Use the maximum interrupting rating of the circuit breaker as the maximum external single phase to ground fault current. \\ h (2) The value RL is based on the distance froin the junction point to the most P distant CT. (3) Calculate a value for VR using P = ?. (4) This value of VR becomes the pickup setting. Begin with Method II. The calculated value of VR is determined as outlined in the paragraph, " Minimum Fault to Trip 87L." If the sensitivity resulting f rom the value calculated is not adequate, then Method I should be used. When the 87L pickup from Method Il proves to yield an adequate sensitivity, a unique advantage is realized, since the 87L picken setting will not require recalculation following changes in system configuration, which would result in higher bus f ault magnitudes. It is desirable for the pickup voltage of the 87L unit to plot below the knee point k of the excitation curve (that is, the point on the enitation curve where the slope is 45 degrees) of all the cts in use. However, it is permissible for the 87L pickup voltage to be higher than the knee point voltage. The maximum setting for the 87L unit is equal to the secondary excitation voltage at ten amperes secondary excitation current (evaluated for the poorest CT in the differential circuit), multiplied by 0.67. Minimum Fault to Trip 87L Unit Af ter the pickup setting of the 87L unit has been established for an application, i a check should be made to determine the minimun internal f ault current which will just cause tne unit to operate. If this value is less than the minimum internal f ault h current expected, the pickup setting is suitable for the application. The following

Figure 8, which is a plot of -the 87H setting in.RMS amperes versus the 87L setting _in RMS volts, illustrates the relationship between these two settings. In order to determine the required 87H setting, it is only necessary to calculate the 87L setting and then enter the curve of Figure 8 at that-value of voltage. e to read the 87H setting directly. SAMPLE CALCULATION The various steps for determining the settings of the PVD relay in a typical application will be explained with the aid of a work 2d example.

l GEK-45405 ) The cable resistance for the longest CT run is given at 250C. If higher ope. rating temperatures are expected, this must be taken into account in determining the maximum expected resistance. Resistance values of wire at 250C, or at any temperature, tl, may be corrected to any other temperature, t2, as follows: Rt2 = 1(t2-tl)]Rt1 I=P where: R 1 = resistance in ohms at tl, degrees Centigrade Rt2 = resistance in ohms at t2, degrees Centigt ade P1 = temperature coefficient of resistance at t1 For standard annealed copper, P1 = 0.00385 at t1 250C; therefore the value of RL at 500C is: Y RL+ 1 + 0.00385 (50 - 25) 0.5 = 0.548 ohms The CT performance f actor, K, must next be determined. To do this, first calculate: (Rs + PR ) (I )~ L F (E ) (N) S i Because Method 'I was selected, use P = 2. From Figure 12, Es = 300 volts [(0.809)+(2)(0.548) (40,000)] = 1.06 (300) (240) h From Figure 7, K = 0.7. Using Equation (5), the appropriate relay setting is: VR =,(1.6) (0.7) [0.809 + (2) (0.548)] (40,000) 240 VR = 355 volts This value is just above the knee point (300 volts) of the CT characteristic, and well below 67 percent of the voltage at ten amperes excitation (0.67) (590) so the application is satisfactory in that respect. Next it is necessary to Aetermine whether the PVD21A or PVD210, or the PVD21C or g PV0210 (one versus two ThyritW r:acks) should be used. First determine the knee point P voltage, Es, for the poorest CT in the circuit. From Figure 12, ES = 300 volts (all cts are assumed to be identical). Assume that the maximum internal f ault current is 45,000 amperes primary, which is equivalent to 188 amperes secondary. The curve of Figure 10, when entered at these coordinates (300 volts and 188 amperes), gows that the application is safe for either the PVD21C or PVD210 relays (two Thy'itW stacks). If Figure 9 were entered at the same coordinates, it would show that PVD21A or PVD21B would not be applicable. The next step in the calculation is to detercine the sensitivity of the relay to internal faults. This may be done using equation (6) as follows: h

If the instantaneous overcurrent unit will be included in the relay, then the PVD21D must be used. To determine the 87H setting, enter the curve of Ff gure 8 at the calculated 87L setting of 355 volts. Read the 87H setting from the scale for the PVC?10 relay. For the 355 volt setting of 87L, the appropriate setting for 87H is 11.8 amperes. RECEIVING, HANDLING AND STORAGE These relays, when not included as part of a control panel will be shipped in cartons designed to protect them against damage, immediately upon receipt of a relay, examine it for any damage sustained in tran';it. If damage resulting from rough handling is evident, file a damage claim at once with the transportation company and promptly notify the nearest General Electric Apparatus S61es Office. Reasonable care should be exercised when unpacking the relay in order that none of the parts are damaged nor the adjustments disturbed. If the relays are not to be installed immediately, they should be stored in their original cartons in a place that is free fran moisture, dust and metallic chips. Foreign matter collected on the outside of the case may find its way inside when the cover is removed, anu cause trouble in the operation of the relay. ACCEPTANCE TESTS g, Immediately upon receipt of the relay, an inspection and acceptance test should be made to insure that no damage has been sustained in shipment and that the relay j calibrations have not been disturbed. These tests may be performed at the discretion of the user, since most operating companies use different procedures for acceptance and installation tests. The following section includes all applicable tests that may be performed on these relays. 6 16 ahaan

Deflect each contact-finger to -insure that there is suf ficient contact force available, and check that each suxiliary brush-is bent high enough to contact the connection plug. Contact 87L The following mechanical adjustments must be checked: 1. The ' armature and contacts of the seal-in unit, as well as the armature and contacts of the instantaneous unit, should move freely when operated by hand. There should be at least 0.015 inch wipe on the seal-in contacts, h 2. the tvgets in the seal-in and the instantaneous unit must come into view and i tch when the armatures are-operated by hand,-and they should unlatch when h rne target release but un is operated. 3.

With the telephone relays in the-de-energized position,.all circuit closing contacts should have a gap of. 0.015-inch,' and all-circuit opening contacts should have a wipe of 0.005 inch. The gap may be checked by inserting a. feeler gage. Wipe can be checked by observing the amount of deflection on the stationary contact before parting the contacts. The armature should then be operated by hand, and the gap and wipe again checked as described above. [ ELECTRICAL SETTING AND INSPECTION Hi-Seismic Instantaneous Unit. 87H Make sure the instantaneous unit link = is in the correct position for the range _in which it is to operate. See internal connections diagram, Figures 3 and 4, and connect - as indicated in the test circuit of Figure 14A. Use the higher ' range - whenever.- possible, since the higher range has a higher continuous rating.- 17 e 1
b GEK-45405 Setting the Hi-Seismic Instantaneous Unit The instantaneous unit has an adjustable core located at the top of the unit. To set the instantaneous unit to a desired pickup, loosen the locknut and adjust the core. Turning the core clockwise decreases the pickup; turning it counterclockwise increases it. Bring the current up slowly until the unit picks up. It may be necessary to repeat this operation until the desired pickup value is obtained. Once the desired pickup value is reached, tighten the locknut. CAUTION: Refer to the RATINGS section for continuous and one second ratings of the instantaneous unit. Do not exceed these ratings when applying current to g the instantaneous unit. The range of the instantaneous unit must be obtained between one-eighth and 20 turns counterclockwise of the core fran the fully clockwise position. Hi-Seismic Target and Seal-in Unit The target and seal-in unit has an operating coil tapped at 0.2 and 2.0 amperes. The relay is shipped from the f actory with the tap screw in the lower ampere position. The tap screw is the screw holding the right had stationary contact. To change the tap setting, first remcVe one screw from the left-hanu stationary contact and place it in the desired tap. Next remove the screw from the urg:; red tap and place it on the lef t-hand stationary contact where the first screw was removed. This procedure is necessary to prevent the right-hand stationary contact from getting out of adjustment. Screws should never be lef t in both taps at the same time, g TABt.E 5 TAP PICKUP CURRENT OR0 POUT CURRENT 0.2 0.15 - 0.195 0.05 or more 2.0 1.50 - 1.95 0.50 or more 87L Unit The 87L unit can be adjusted at any voltage within the range shown on its calibration plate. Four specific calibration values, for both the high and low voltage range are shown on the plate, which correspond to the values stamped on the nameplate. The 87L unit, unless otherwise specified on the requisition, will be set at the f actory g to operate at its minimum pickup voltage. If the unit is to be set at some other point, the calibration marks should be used as a guide in making a rough adjustment, and the test circut of Figure 148 should then be used to make an exact setting. When the test plug is inserted in the relay, as depicted in Figu.e 14B, the current transformer secondaries are shorted by means of the link between the outer terminals 5 and 6. The adjustable test voltage is applied across terminals 5 and 6 of the relay; that is, across the voltage circuit which includes the 87L unit. Since the continuous voltage rating of the resonant circuit is only 150 volts, it is recommended that a hand-reset lockout relay be used in the test setup if the desired 87L setting is g Y to be above this figure. 18
GEK-45405 The following procedure shouid be f ollowed in checking pickup of the 87L unit, g Start with a test voltage considerably higher than the expected operating point. Lower the test voltage by successively smaller increments, closing the test switch at each point. The lockout relay will operate each time, protecting the resonant circuit. Eventually, a point will be reached where the 87L unit will just f ail to operate. The preceding voltage value, therefore, is the pics.ap value of the 87L unit (within reasonabit accuracy). At the point where the 87L unit f ails to pic< up, the test voltage must be removed at once to prevent damage to the relay. 6 If the 87L unit setting is to be less than the 150 volt continuous rating, it will not be necessary to use the lockout relay. Tht: voltmeter used must have high internal impedance. Tne 87L unit operating time can be checked by using the test circuit shown in Figure 14B and measuring the time elapsed between application of the input voltage and the operation of the 87L output contacts. The times measured should be within plus three and minus seven milliseconds of the time shown in Figure 15. Thyritt@ Unit Apply 120 volts direct current to studs 3 and 6. lhe current should be between 0.005 and 0.012 amperes,f or a single slack, and between 0.010 and 0.024 amperes for a double stack of ThyritF. The Thyrit @ is very voltage sensitive, and should be set carefully. Also, any meter error in the voltmeter will be magnified four to five times, for example, a three percent meter error will have an effect on the current of F t rom 12 to 15 percent. INSTALLATION PROCEDURE LOCATION AND MOUNTING The relay should be mounted on a vertical surf ace in a location reasonably free from excessive heat, moisture, dust and vibration. The relay case may be grounded using at least #12 AWG gage copper wire. The outline and panel drilling dimensions for Type PVO relays are shown in Figure 1. CONNECTIONS Internal connections diagrams for the Type PVD21A and PV021C, and the Type PVD21B I and PVD210 relays, are shown in Figures 2 and 3, respectively. The elementary diagram D of the external connections for a typical application is shown in Figure 4. Note in Figure 4 that when the relay is installed, a connecting jumper should be placed between terminals 4 and 5, and that terminals 5 and 6 are then connected across differential junction points A and B of the several curred transformers. A shorting bar is provided between terminals 6 and 6 a that if the conriection plug of the relay is withdrawn, the differential circuit will hot be opened. The midpoint between the Thyrith stack and unit 87H is connected to terminal 3. This makes it possible to test or calibrate unit 87H without the necessity of passing 9
- Indicates Revision 19
GEK-45405 high current through the Thyrith, and makes it possible to short out the 07H coil when its operation is not necessary. The external connections in Figure 4 indicate that the diff erential junction, points A and 8, should be located in the switchyard. This is important in outdoor installations where the distance between the breaker and relay panel may be great, since the resistance through the f ault CT loop may otherwise be too large. The junction points can be located at the panel, provided that the necessary relay setting gives the desired sensitivity. There should be only one ground connection in the secondary circuit. When the g junction points are located in the switchyard, the ground connection should be made there rather than at the panel. The voltage limiting Thyrith is short-time rated. The contacts of the auxiliary relay device 86 short circu;ts the differential circuit to protect it. CAUTION: UNDER NO CIRCUMSTANCES SHOULD THE RELAY BE PLACED IN SERVICE WITHOUT THE THYRITE VOLTAGE LIMITING CIRCUIT CONNECTED; THAT IS, WITHOUT A JUMPER BETWEEN TERMINALS 4 AND 5. OTHERWISE, THE RELAY AND SECONDARY WIRING WILL NOT BE PROTECTED FROM lilGH CREST VOLTAGES WHICH RESULT FROM AN INTERNAL FAULT. VISUAL INSPECTION Repeat the items described under ACCEPTANCE TESTS, VISUAL INSPECTION. g MECHANICAL INSPECTION AND ADJUSTMENTS Repeat the items described under ACCEPTANCE TEdfS, MECHANICAL INSPECTION. TARGET / SEAL-IN UNIT Set the target / seal-in unit tap screw in the desired position. The contact adjustment will not be disturbed if a screw is first transferred fram the lef t contact to the desired tan nntitinn on the right contact, and then the screw in the undesired tap is removed and transferred to the left contact. 87H AND 87L UNITS Ref er to the appropriate descriptions in ACCEPTANCE TESTS for the proper method of a T setting the 87L and 87H units. The external trip ci?cuit wiring to the relay, as well as the relay itself, should be checked by operating one of the relay units by hand and allowing it to trip the breaker or lockout relay. Observe that the target operates upon manual operation of the relay unit. 20 j
e GEK-45405 O PERIODIC CHECKS AND ROUTINE MAINTEhANCE in view of the vital role of protective relays in the operation of a power system, it is important that a periodic test program be followed. The interval between periodic checks will vary depending upon environment, type of r elay and the user's experience with periodic testing. Until the user has accumulated enough experience to select the test interval best suited to his individual requirements, it is suggested that the points listed under INSTALLATION PROCEDURE be checkec at an interval of from one to two years. Check the items descrited in ACCEPTANCE. TESTS, both VISUAL and MECHANICAL INSPECTION. Examine each component for signs of overheating, deterioration, or other damage. Check that all connections are tight by observing that the lockwashers are fully collapsed. CONTACT CLEANING Examine the contacts for pits, arc or burn marks, corrosion and insulating films. A flexible burnishing too? should be used for cleaning relay contacts. This is a which in effect resembles a flexible strip of metal with an etched-roughened surf ace, licate that no scratches are superfine file. The polishing action of this file is so de lef t on the contacts, yet it cleans off any corrosion thoroughly and rapidly. The flexibility of the tool insures the cleaning of the actual points of contact. Relay contacts should never be cleaned with knives, files, or abrasive paper or cloth, PERIODIC TEST EQUIPMENT A test set is available for periodic testing of PVD relays. It is intend 9d to be mounted on the panel adjacent to the relays, and in addition to testing, it can also be used to check current transformers for open or short circuits, and incorrect wiring. This test set is more fully described in instruction book gel-50290. ELECTRICAL TESTS Pickup of the 87L and 87H units should be measured and the results compared against the desired setting. If a measured value is slightly different from that measured previously, it is not necessarily an indication that the relay needs readjustment. The errors in all the test equipment are additive, and the total error of the present setup may be of opprsite sign from the error present during the previous periodic test. Instead of readjusting the relay, if the test results are acceptable, 4 no adjustment shoul-d be made. Note the deviation on the relay test record. After sufficient test data has been accumulated, it will become apparent whether the measured deviations in the setting are due to random variations in the test conditions, or are due to a drift in the relay characteristics. THYRITL@ UNIT Repeat the test described in ACCEPTANCE TESTS, ELECTRICAL INSPECTION. 4 21 I
t GEK-45405 4 Hi-SEISMIC INSTANTANEOUS UNIT 87H ( Check for the following: 1. Both contacts should close at the same time. 2. The backing should be so formed that the forked end (front) bea/s against the molded strip under the armature. 3. With the armature against the pole piece, the cross member of the "T" spring should be in a horizontal plane, and there should be at least 0.015 inch wipe g on the contacts. Check by inserting a.0.010 inch feeler gage between the-front half of the shaded pole with the armature held closed. The contacts-should close with the feeler' gage in place. HI-SEISMIC TARGET AND SEAL-IN UNIT Check steps 1 and 2 as described in the paragraph 'above for the-instantaneous unit. To check the wipe of the seal-in unit, insert a 0.010 inch feeler--gage between the plastic residual bump of the armature and-the pole piece _with the armature held closed. The contacts should close with the feeler gage in place.- RENEWAL PARTS Sufficient quantities of renewal parts should be kept in stock for the prompt- .g replacement of any that are worn, broken or damaged. When ordering renewal parts, address the nearest Sales Office of L the General Electric Company. Specify the name of the part wanted, quantity required, and catalog numbers as shown in Renewal Parts Bulletin GEF-4543, i 6 22 m,_ _ __ - _ - -_._-
