* Depending on the set tr_U ratio (ratio of the voltage transformer: 0.1...4000.0)
and tr_I ratio (ratio of the current transformer: 1...10000)
r - of the range
mv - of the measured value
Caution! For the correct current measurement the presence of a voltage
higher than 0.05 Un is required at least in one of the phase
