Maximum Deviation From Average Voltage
Average Voltage
Example: Supply Voltage is 400V - 3ph - 50Hz
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 maximum deviation from 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
