Step 7/7
Check voltage metering for the phase on the protection relay LHMI Measurements view.
Figure 44: Measurements view, injected phase 1
Since the protection relay is reporting phase-to-phase voltages, two identical measurements
will appear on the display. For example, if voltage is applied between phase 1 and the ground,
then the protection relay shows U
12
= U
31
and U
23
= 0.
