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 =

Mode 2: Non-active power calculation (nAct)
Active power is measured directly, apparent power S = V

Mode 1 is recommended for electrical networks with low harmonic distortion (voltage

<
5%, current THD
<
10%); Mode 2 is recommended for all other cases.
Energy roll value example: If roll value = 10.E4, the energy counter contains 4 digits,
i.e., energy is displayed up to 9.999 MWh (Mvarh, MVAh) with resolution 0.001 MWh.

The roll value may be changed in accordance with the average load of the power line.
For example, if average power is 400 kW and the counter must be reset every 3 months
(2160 hours), then energy during this period equals 864000 kWh (6 digits) and the roll
value = 10.E6.
