2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supplyvoltage is greater than 2%. Use the following formula to de-termine the percentage of voltage imbalance.
% Voltage Imbalance = 100 xmax voltage deviation from average voltage
average voltage
Example: Supply voltage is 230-3-60
AB = 224 vBC = 231 vAC = 226 v
Average Voltage =(224 + 231 + 226)
=681
3 3
= 227
Determine maximum deviation from average voltage.(AB) 227 – 224 = 3 v(BC) 231 – 227 = 4 v(AC) 227 – 226 = 1 vMaximum deviation is 4 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x4
227
= 1.76%
This amount of phase imbalance is satisfactory as it is below themaximum allowable 2%.IMPORTANT: If the supply voltage phase imbalance is more than2%, contact your local electric utility company immediately.
