When calculating the voltage to be applied into the phase-to-phase voltageenergizing inputs, calculate as follows:* Rated voltage, 100, 110, 115 or 120 V, of the relay energizing input to be testedThis gives the voltage to be applied during the test as follows:* Applied voltage (V) = 2 ×U>>× rated voltage of the energizing inputTo perform the test, apply the voltage in all three phase-to-phase voltage energizinginputs. The output contacts, to which the trip signal is routed from the overvoltageprotection function, should be activated on the expiration of the set operate time ofstage U>>.5.6.2. Testing residual voltage protectionWhen calculating the voltage to be applied into the residual voltage energizinginput, calculate as follows:* Rated voltage, 100, 110, 115 or 120 V, of the relay energizing input to be testedThis gives the voltage to be applied during the test as follows:* Applied voltage (V) = 2 ×U0 >× rated voltage of energizing inputTo perform the test, apply the voltage in the residual voltage energizing input. Theoutput contacts, to which the trip signal has been routed from the residual voltageprotection stage, should be activated on the expiration of the set operate time ofstage U0 >.54REU 610REU 610 Voltage Protection RelayOperator's Manual1MRS755770 |
