4.4.3.3 Functionality
The phase reversal protection function 46R is used to detect the reversed connection of the
phases to a three-phase motor by monitoring the negative phase sequence current I
2
of the
motor.
46R picks up and trips when I
2
exceeds the set limit. 46R operates on definite time (DT)
characteristics. 46R is based on the calculated I
2
, and the function detects too high I
