11.4.14 Phase preference logic PPLPHIZ
Prepare the IED for verification of settings outlined in Section
settings".
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 (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
Line distance protection REL670
