Never operate a motor where phase imbalance in supply voltage is greater than 2%.
Use the following formula to determine the percentage of voltage imbalance
Average Voltage
= 100 X
Determine maximum deviation from average voltage.
IMPORTANT: If the supply voltage phase imbalance is more than 2% contact your local electric utility company

Imbalance
= 100 X = 1.76%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%
Average Voltage =
392 + 404 + 395 Maximum Deviation is 7v.
