Power calculation mode (P.cAL):
Mode 1: Reactive power calculation (rEAc)
Active power P and reactive power Q are measured directly and apparent power
S =
√ P 2 + Q 2
Mode 2: Non-active power calculation (nAct)
Active power is measured directly, apparent power S = V × I (where V, I - rms
voltage and currents) and non-active power N = √ S 2 - P 2
Mode 1 is recommended for electrical networks with low harmonic distortion (voltage
THD
< 5%, current THD < 10%); Mode 2 is recommended for all other cases.
