1 Power calculation mode (P.cAL):
Mode 1: Reactive power calculation (rEAc)
Active power P and reactive power Q are measured directly and apparent
power:
2 2
Q P S + =
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:
2 2
P S N − =
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.
