Solution: PF value depends on current and voltage phase angle. First, check the voltage Phase angle in the meter it should be 0, 120, 240. and verify the CT and PT connection in meter accordingly RYB. An issue on the site: PF value does not change ...
Please find the below images of the EN meter display to understand the situation of a meter. As shown in the above images we can see in the Y phase PF & KW is very less compare to the other two-phase. Here KW depends on the PF value because of PF ...
Consumption Load If users are metering a load that is consuming energy, seeing negative power (kW) readings would cause errors when reading the total consumed energy on the meter. Negative readings can be a result of the following: CT reversal: If ...
