What is the basic working principle of a capacitor cabinet? In the actual power system, most of the loads are asynchronous motors. The equivalent circuit can be regarded as a series circuit of resistor and inductor, with a large phase difference between voltage and current and a low power factor. When a capacitor is connected in parallel (as
Capacitors in the cabinet act as a source of reactive power. It neutralizes the reactive power used by motors or transformers in the case of heavy loads. This assists in the phase connection of voltage and current so that energy is optimized in your system.
These devices detect the phase angle between the current and voltage, identifying when reactive power compensation is needed. Activation of Capacitors: Once a need for reactive power compensation is identified, the control system activates the appropriate capacitors within the cabinet. This activation is dynamically adjusted to match the exact needs

The selective capacitor from the bank will be switched ON/OFF based on reactive power being compensated. This design shows the switching of the capacitor bank in five steps for improving the lagging PF (towards unity). This is implemented by switching three relays and two transistor outputs.
With proper sizing of the capacitor, the leading capacitive current introduced can neutralize the lagging inductive current (and vice versa) thereby reducing the reactive current considerably in the circuit. This is the essence of improving the PF.
Conventional switching — Contactor: Contactors are electrically controlled switches for handling higher currents. They are used when the variation in reactive power is slow and the capacitor switching interval is in increments of seconds. Capacitors draw very large transient currents when they are switched in and out.
Power factor correction (PFC) capacitors produce the necessary leading reactive power to compen-sate the lagging reactive power. They should be capable of withstanding high inrush currents caused by switching operations (> 100 x IR).
Capacitor duty contactors have additional auxiliary contacts with current limiting resistors (pre-charging resistors) in series. The auxiliary contacts come on first, and then the main contacts take over the steady state current of the capacitors.
These capacitor banks are switched on either manually (using circuit breaker or switches) or semi-automatically by a remote-controlled contactor. Automatic power factor correction (APFC): For loads that require varying reactive power, APFC is used. Also, under light load conditions, a fixed capacitor provides a leading power factor.
