ohms law: V = IR
you know the current rating, you take the machine
resistense using megger. calculate the voltage rating of
machine.
1 phase: power = V * I * power factor (watts)
3 phase: power = 1.732 * V * I * power factor (watts)
ENERGY (KWH) = POWER * TIME
so, we can calculate the KWH or MWH of the machine....
