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
12
= U
31
and
U
23
= 0.
