Then inject relevant voltage and current in such a way that above impedance value
is measured by the ZGTPDIS function.
1. Change the magnitude and angle of the phase-to-phase voltage to achieve
impedances at test points P1, P2.....,P10.
2. For each test points, check that the output signals START and STZx (where, x
is 1- 3 depending on the zone selected) are activated.
3. Signals TRIP and TRZx will be activated after operate time delay
tZx
for the
respective zone has elapsed.

. Restore connections and settings to their original values, if they were
changed for testing purposes.
