The Fault Simulation State allows adjustment of all current and voltage phasors so
that a wide variety of system disturbances 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 equivalent 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
are entered in per unit values relative to the nominal system current that is defined
by the setpoint. All phasor angles are referenced to the prefault A-

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°.
