The Fault Simulation State allows adjustment of all current and voltage phasors so that a wide variety of system distur-
bances can be simulated. The frequency and the analog input values can also be adjusted to give complete flexibility. Fault
bus voltage values are always entered as Wye values, even if the relay is set to Delta. The relay will calculate the equiva-
lent line voltages. Voltage magnitudes are entered in per unit values relative to the nominal system voltage that is defined
by the
NOMINAL VT SECONDARY VOLTAGE and VT RATIO setpoints. Phase current magnitudes are entered in per unit values
relative to the nominal system current that is defined by the PHASE CT PRIMARY setpoint. All phasor angles are referenced to
the prefault A-N bus voltage at 0°.
e) POSTFAULT VALUES
PATH: SETPOINTS ÖØ S8 TESTING ÖØ SIMULATION ÖØ POSTFAULT VALUES
The Postfault State allows adjustment of the bus and line voltages in order to simulate an open breaker condition and allow
testing of the synchrocheck feature. All phasor angles are referenced to the prefault A-N bus voltage at 0°.
