Power Factor Correction Transformers & Power Factor Calculations
If you want to understand the calculation of power factor and its correction, you need to understand a few terms, which we'll discuss here. KW is the amount of power by which the transformer does useful work. It is also called active power, real power, or actual power. KVAR is used to denote reactive...
Factor from Table 1 below x kW = kVAR of capacitors required.
Calculation Example : 1 unit air-compressor ( 3 phase 415 VAC ) used an average of 90 kW with an existing power factor of 80%.The desired power factor is 95%. The factor value for this case is 0.421 to raise the power factor from 80% to 95% using table 1. 0.421 x 90 kW = 38 kVAR.
