Phase preference logic PPLPHIZ

Prepare the IED for verification of settings outlined in section "Requirements" and section
"Preparing for test" in this chapter.
The Phase preference logic function PPLPHIZ is tested with a three-phase testing equipment
for distance protections. PPLPHIZ is tested in co-operation with the Distance protection zone,
quadrilateral characteristic function ZMQPDIS. 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
Start 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 earth 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 two phase-to-earth faults with one phase current are
tested. The result shall be according to table 31. It should be checked that the fault will
give phase-to-phase voltage, phase-to-earth voltage, zero-sequence voltage and phase
current so that the conditions set for the logic are fulfilled.
