Capacitor compensation cabinet basic knowledge

First, what is capacitive compensation?

电容补偿柜基础知识

Capacitor compensation is reactive compensation or power factor compensation. The power system of the power system generates reactive power during use, and is usually inductive, which reduces the capacity efficiency of the power supply, and can be improved by appropriately increasing the capacitance in the system. Power capacitor compensation is also known as power factor compensation.

The power factor is an important technical data for the power system. The power factor is a coefficient of measuring the efficiency of electrical equipment. The power factor is low, indicating that the circuit is used to alternate the magnetic field conversion, thereby reducing the utilization of the device, increasing the line power loss.
