Average L-N Voltage
Average L-N Voltage (Parameter 60) reports the average voltage of the monitored
L-N voltages. When Single or Three Phase (Parameter 176) is set to
Three Phase
,
Average L-N Voltage is calculated as follows:
Average L-N Voltage = (L1-N V L2-N V L3-N Voltage) / 3
When Single or Three Phase (Parameter 176) is set to
Single Phase
, Average L-N
Voltage is calculated as follows:
Average L-N Voltage = (L1-N V L2-N Voltage) / 2
Table 408 - Average L-N Voltage (Parameter 60)
Voltage Imbalance
Voltage Imbalance (Parameter 61) reports the percentage of uneven voltage being
supplied by the monitored power system. Voltage Imbalance is defined by the
following equation:
Voltage Imbalance = 100% * (Vd/Va)
where
Vd = Maximum L-L Voltage Deviation from the Average L-L Voltage
Va = Average L-L Voltage
