Remark 1：The accuracy of electric energy measurement is the same as the corresponding power measurement accuracy.
Remark 2： P/Q/S Accuracy of measurement under the condition of the power factor > 0.25.
Function advantage:
High stability of active compensation current transformer, wide measuring range, high precision, good stability for a long time
Can measure the voltage, current, frequency, phase and active/reactive power, apparent power at the same time.
With many kinds of reactive algorithm
Can output active and reactive power signals at the same time, also can output a variety of apparent power signal
