Check also in the same way as for phase-to-ground fault for each test point that the output
signals PHG_FLT, are activated where x refers to the actual phase to be tested. After the timer
for the zone has elapsed, also the signals TRIP, TRPG and TR_x shall be activated.
11.4.4 Faulty phase identification with load encroachment FMPSPDIS
(21)
There is no specific test routine for this function. The function is tested in conjunction with other
impedance (mho) functions.
11.4.5 Distance protection zones, quadrilateral characteristic, separate
settings ZMRPDIS (21)
Prepare the IED for verification of settings as outlined in section
chapter.
Consider releasing Zone 1 with the Phase selection with load encroachment, quadrilateral
characteristic (FRPSDPIS). If the autorecloser is not released and in service, trip will always be
three phase.
