Unbalanced 3-Phase Supply Voltage
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
Maximum Deviation From Average Voltage
= 100 X
Example: Supply Voltage is 400V - 3ph - 50Hz
AB = 392v
Average Voltage =
BC = 404v
AC = 395v
=
Determine maximum deviation from average voltage.
(AB) 397 - 392
=5v
(BC) 404 - 397
=7v
(AC) 457 - 397
=2v
Maximum Deviation is 7v.
Determine Percentage Voltage Imbalance.
% Voltage Imbalance
= 100 X
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
