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 ...
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 ...
1. LL - voltage line to line Measurement of voltage line to line depends on PT ratings programmed in the meter and the supplied voltage. For example : PT primary = 11000 V PT secondary = 110 V Input Voltage at meter terminals = 100 V Amps average = ...
Accuracy is claimed only for FULL SCALE reading in the IELR Meter- Meaning, Accuracy limits are to be only calculated for 12 Amps - in 300mA to 12A Meter 30 Amps- in 30mA to 30A Meter.(Latest Model) The accuracy class is 2% for all ranges of CBCT & ...
