Example: Supply Voltage is 400V - 3ph - 60Hz
Maximum Deviation From Average Voltage
Average Voltage
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%
IMPORTANT: If the supply voltage phase imbalance is more than 2% contact your local electric utility company
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
Determine Percentage Voltage Imbalance.
