Thanks for your reply.
If you multiply volts of phase A of (MTR ROOM 79) with the Amps on the same phase, 234.5Volts X 11.31Amps =2652.195Watts, Where as in the attached pic it shows 1327Watts.
This is how i am reaching the conclusion that the data shown for Phase A is not correct.
power factor = active power/U*I
Power factor is an expression of energy efficiency. It is usually expressed as a percentage—and the lower the percentage, the less efficient power usage is.
This is the power factor explanation,
The power factor is just a measurement result, and can not be disabled, please try to understand what is the power factor before your continue question.
