1.
Inject the magnitude and angle of phase-to-phase voltage to achieve impedances at test points
P1, P2, …, P9.
2.
Test points P7 and P9 are intended to test the directional lines of impedance protection and
used to find directional accuracy for phase-to-phase faults.
3.
For each test point, observe that the start output signals START, STZx, STNDZx, STL1, STL2
and STPP are activated.
4.
Trip signals TRIP, TRZx, TRL1 and TRL2 will appear after set delay time of
tPPZx
if
OpModetPPZx
is set to On and
TimerSelZx
is set to Timers separated.
