Power factor correction may be used to counteract the distortion and raise of the power factor in an Electrical system. It is always better to have the power factor of a system to near 1.0. Power factor which is below 1.0 requires a utility to generate more than the minimum volt-amperes, which is necessary to supply the real power (watts). This tutorial will teach you how to find the PF correction value with the proper given inputs.
PF - Power Factor KW - KiloWatts kVA - Kilo Volt Amperes
An electric motor has a power factor of 0.8 and its expected power factor is 0.9. Power rating of a device connected to the electric motor is 100KW. Find the power factor correction for the given values?
Connected Load = 100 KW Current PF = 0.8 Desired PF = 0.9
Power Factor Correction
Substitute the given values in the formula,
Original KVA = KW / Current PF Original KVA = 100 / 0.8 Original KVA = 125 New KVA = KW / Desired PF New KVA = 100 / 0.9 New KVA = 111
