We have a 3 phase electronic motor with a 'useful' power 4kW. Its efficiency is 80% Currents on the lines are equal in all three phases, and they are lagging behind the voltages by 30 degree. We need to make a power factor correction in such a way, that the phase difference between the current and voltages becomes less than 10 degree.
And I am totally lost.
Is the efficiency the power factor? Do we have to do anything by the fact that it is lagging? (Other than it shows that we need to use a capacitor for the correction?) Why less then 10 degree and not zero?
Tried looking up videos and googling, but that only made me more confused :/
ps: Voltage is 230 Volt and 50 Hz. If the example needs this information.
