Principle and Application of Power Capacitor Compensation



Power capacitor container is a common equipment to improve power quality, reduce power loss, and improve the utilization rate of power supply equipment. The risk of explosion of the capacitor in operation and the danger of residual charge of the capacitor after power failure are safety issues that must be paid attention to.
In the power system, the most convenient way to improve the power factor is to connect the capacitor in parallel, generate the leading capacitor current to offset the backward inductor current, and reduce the so-called reactive current that does not do work to a certain range.
Power capacitors for compensation are either installed on the high-voltage side or on the low-voltage side; It can be installed centrally or decentralized. From the perspective of compensation improvement, high voltage compensation is better than low operation compensation, and centralized compensation is better than decentralized compensation.
