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!
CALL LOCAL POWER COMPANY FOR ASSISTANCE.
