Principle of capacitor compensation power

Another positive effect of the dynamic reactive power system is the ''soft'' switching of the capacitors.. Conventional equipment with air contactors creates transient inrush currents which not only affect the compensation components, but can also lead to damage and perturbations (or distortions) of consumers. The real-time power factor compensation …

Reactive Power Compensation of Reactive Components

In a DC circuit, the product of "volts x amps" gives the power consumed in watts by the circuit. However, while this formula is also true for purely resistive AC circuits, the situation is slightly more complex in an AC circuits containing reactive components as this volt-amp product can change with frequency affecting the circuits reactive power.
