Check voltage metering for the phase on the voltage sender protection relay LHMI Measure-
ments view.

Check voltage values for the phase on the voltage receiver protection relays LHMI Measure-
ments view.
The voltage value must be identical with the voltage sender protection relay and without
brackets around the value.

Figure 49: 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
1 VLG 500 0 17 C
= U and U = 0.
