Question

A single phase motor operating at a 400v,50hz produce an out our of 10kw with an efficiency of 84percent and a power factor of 0. 7 lagging.
Calculate input kilovolts-ampere
The active and reactive component of the current
The reactive kilo-ampere

Answer 1

Answer:

it is required to raise the supply power factor to 0.9 lagging. Determine the value of the capacitance required in parallel with the motor to achieve this correction
