ZDDQ Engineers give an example for reference, An Alternator is supplying a load of 650 kW at Power factor 0.65. What size of Capacitor banks (kVAR) is required to raise the Power Factor to unity (1 or >0.95)? And how many more kW can the alternator supply for the same kVA loading when P.F improved. Supplying kW = 650 kW Original P.F = Cosθ1 = 0.65 Final P.F = Cosθ2 = 1 θ1 = Cos-1 = (0.65) = 49°...

Why harmonics analysis? When a voltage and/or current waveform is distorted, it causes abnormal operating conditions in a power system such as: Voltage Harmonics can cause additional heating in induction and synchronous motors and generators. Voltage Harmonics with high peak values can weaken insulation in cables, windings, and capacitors. Voltage Harmonics can cause malfunction of different elect...
