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.

Completing the test

Continue to test another function or end the test by changing the TestMode setting
to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.
