The Phase preference logic function PPL2PHIZ is tested with a three-phase testing equipment for
distance protections. PPL2PHIZ is tested in co-operation with the High speed distance protection
ZMFPDIS (21). The distance protection and the phase preference logic shall be set to values according
to the real set values to be used. The test is made by means of injection of voltage and current where the
amplitude of both current and voltage and the phase angle between the voltage and current can be
controlled.
During the test the following binary signals (outputs) shall be monitored:
• Trip signal from distance protection
• Trip signal from phase preference logic
1. Connect the test set for injection of voltage and current.
2. Inject voltages and currents corresponding to a phase-to-phase to ground fault within zone 1 of the
distance protection function. In the test one of the current inputs (one of the faulted phases) is
disconnected. The remaining current is the fault current out on the protected line. All combinations of
