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
32
= U and U = 0.
