Example:

L1 measured = 221 V

L2 measured = 230 V

L3 measured = 227 V

Note: L1 = 221 volts is the maximum deviation of the 3

voltages from the average of the 3 voltages.

Therefore, the imbalance percentage is:

The 2.2 % imbalance that exists in the example above

exceeds the maximum allowable imbalance between

phases.

221 + 230 + 227

= 226 volts

100 (226 – 221)

= 2.2%

226
