Revision 11 (05/01)Waterford SteamElectric Station #3UNDERVOLTAGE RELAY CRITERIA-TEST CURVEFOR RELAYS 27-1.2.3Figure8.3-37 WSES-FSAR-UNIT-3NOTES TO FIGURE 8.3-37Revision 11 (05/01)1.Percent Values are based on 4160 volts.2.This test curve also applies to 27-1, 2, 3/AB relays.

3.For relays 27-1, 2, 3/AB the tap setting is 93 volts and time dial.

4.For undervoltage detection scheme, see FSAR Figures 8.3-5 and 8.3-6.

5.The relay operation, upon total loss of voltage, is as follows:1)Nominal voltage is 4160 volts (118.86 volts secondary).

2)Loss of voltage.

3)The 27-1, 2, 3/A(B) relays sense loss of voltage at 3675 volts (i.e., 88.3 percent ofnominal 4.16 KV bus voltage).

The 27-1, 2, 3/A1(B1) relays sense low voltage at 3875 volts (i.e., 93.1 percent ofnominal 4.16 KV bus voltage).4)The 27-1, 2, 3/A(B) relays close their contacts after two seconds and the diesel startsand accelerates to full speed within 10 seconds (the operations of the 27-1, 2, 3/A1(B1) relays is not considered in the total loss of voltage event, because the 27-1, 2, 3/A(B) relays trip ahead of them to generate the LOVS). For a description of the operation of the 27-1, 2, 3/A1(B1) relays, see Table 8.3-14).5)Diesel Generator breaker closes automatically. (DRN 99-2345)6)Relays IAV55C reset within the minimum required EDG output voltage (opencontacts). (DRN 99-2345)7)Automatic loading sequence commences and loads are applied in sequence shown inFSAR Table 8.3-1.GENERAL:Equipment protection during the low voltage condition is accomplished by theoperation of relays 27-1, 2, 3/A, A1, B, B/1 and AB which provide a LOVS if the bus voltage is below the time-voltage characteristic of the relays.
