In electrical design, reactive power compensation cabinets are centrally installed on the low-voltage side of the power distribution room. The corresponding compensation installation capacity is marked on the drawings. However, due to the differences in the rated voltage of the capacitors, the access voltage at the compensation cabinet, and the reactance of the series reactors, the actual output c...

In power distribution systems, capacitor banks compensate for the reactive power generated by inductive loads using parallel-connected low-voltage power capacitors; this improves the power factor, reduces line losses, and avoids utility company penalties. However, a common misconception exists: the belief that the more capacitors are engaged—and the higher the resulting power factor—the better. In...

1.Why is reactive power compensation necessary? Reactive power is by no means useless power. In AC power supply systems, inductors and capacitors serve as essential loads. Ferromagnetic loads—such as electric motors and transformers—cannot function without inductive reactive power for excitation; meanwhile, long-distance transmission lines possess inherent capacitive characteristics, effectively a...
