Change the magnitude and angle of phase-to-phase voltage to achieve impedances at
test points 1, 2 and 3. For each test point, observe that the output signals, PICKUP and
TRx are activated where x refers to the actual phase to be tested. After the timer tPP
for the actual zone has elapsed, also the signals TRIP and TRx shall be activated.
Phase-to-ground faults
For simplicity, the same test points as for phase-to-phase faults are proposed, but
considering new impedance values.

1 X ZPE · sin(ZAngPE)
R ZPE · cos(ZAngPE)
2 X 0,5·ZPE · sin(ZAngPE)
R 0,5·ZPE + ΔR = 0,5·ZPE · (1 - cos(ZAngPE))
3 X 0,5·ZPE·sin(ZangPE)
R 0,5·ZPE - ΔR = 0,5·ZPE · (1 - cos(ZAngPE))
Check also in the same way as for phase-to-ground fault for each test point that the
output signals TRIP and TRx are activated where x refers to the actual phase to be
tested. After the timer tPE for the zone has elapsed, also the signals TRIP and TRx
shall be activated.
