Power Calculation Modes
The power calculation mode option allows you to change the method for
calculating reactive and apparent powers in presence of high harmonics.
The options work as follows:
When the reactive power calculation mode is selected, active and
reactive powers are measured directly and apparent power is
calculated as:

This mode is recommended for electrical networks with low harmonic
distortion, commonly with THD < 5% for volts, and THD < 10% for
