Voltage Imbalance
Description
The line voltage imbalance function displays the maximum percentage of deviation between the average voltage and the individual line voltages.
The three-phase voltage imbalance is calculated using formula:
Where,
-
VLx= Maximum deviated line voltage from average voltage
-
Vavg = Average voltage of the three phases
NOTE: Not applicable in single-phase mode.
