METERING
MOTOR
There are three metered values available for the motor.
MOTOR LOAD
— This value represents the measured three phase average RMS current from the line source divided by the
Full Load Amps setting, in per unit.
MOTOR UNBALANCE
— This value is the amount of unbalance in the motor currents. An explanation of the calculation of this
value is presented for the AMP Unbalance element.
U/B BIASED MOTOR LOAD
— Unbalance Bias Motor Load shows the equivalent motor heating current caused by the
unbalance k factor.
