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 two phase-to-ground faults with one phase current are tested. The result
shall be according to table 37. It should be checked that the fault will give phase-to-phase
voltage, phase-to-ground voltage, zero-sequence voltage and phase current so that the
conditions set for the logic are fulfilled.

PHPIOC (50)
Prepare the IED for verification of settings outlined in Section
settings".
Values of the logical signals for PHPIOC are available on the local HMI under Main menu/Tests/
Function status/Current protection/InstPhaseOverCurrent(50,3I>>)/PHPIOC(50;3I>>):x, where x
= 1, 2, and 3.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
To verify the settings the following fault type should be tested:
• Phase-to-ground fault
Line distance protection REL670
