CHECK VOLTAGE IMBALANCE

 

 

LINE-TO-LINE VOLTS: AB________ V

AC________ V

BC ________ V

(AB + AC + BC)/3 = AVERAGE VOLTAGE = _________ V

 

MAXIMUM DEVIATION FROM AVERAGE VOLTAGE = _________V

 

VOLTAGE IMBALANCE = 100 X (MAX DEVIATION)/(AVERAGE VOLTAGE) = _________ %

IF OVER 2% VOLTAGE IMBALANCE, DO NOT ATTEMPT TO START SYSTEM!
