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...

An example of how to calculate the capacity of reactive power (kVAr)? An Motor is supplying a load of 700 kW at a P.F (Power factor) of 0.65. What size of Capacitor in kVAr is required to raise the P.F (Power Factor) to unity (1)? And how many more kW can the motor supply for the same kVA loading when P.F improved. Supplying kW = 700 kW Original P.F = Cosθ1 = 0.65 Final P.F = Cosθ2 = 1 θ1 = C...

ZDDQ-SVG Static Var Generator is an electronic reactive power compensation system, for both capacitive and inductive power. It has the same operating principle as an active filter; the SVG injects a current in the opposite direction to counteract the installation's non-useful power (inductive and capacitive), thus ensuring that the target cosϕ is achieved. ZDDQ SVG instantly compensates and adjust...
