BCPM’s are reading a incorrect power factor for each phase.


28 February 2022

BCPM’s are reading a power factor for each Phase A ,B ,C as 0.9, 0.6, and 0.3 respectively.

However the power factor should be roughly 0.9 for all 3 phases. 

Voltage Taps and the Incoming CTs have been checked but have not yielded any results as to what could cause the power factor discrepancy on each phase.

Resolution is to check the register for 62017 which is a user defined setting which handles the phase assignment being enabled/disabled. 

Changing the bit value 0 of register 62017 from 1 to 0 disables this feature.
