 DIFFERENTIAL
The phasors of differential and restraint currents are displayed in primary amperes.

6.3.3 Motor

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