Electrothermal high-voltage dry parallel capacitor: an electric artifact to improve power factor

1. Working principle of electrothermal high-voltage dry parallel capacitor
In AC power system, the phase difference between current and voltage is the main reason for the reduction of power factor. Especially for inductive loads, such as motors and transformers, they need to consume a lot of reactive power during operation, which makes the current lag behind the voltage and the power factor decreases. The reduction of power factor will not only increase the line loss of the power system, but also reduce the utilization efficiency of power equipment, and may even affect the stability of the power system.

Electrothermal high-voltage dry parallel capacitor is designed to solve this problem. It provides additional reactive power by connecting to the power system in parallel, thereby compensating for the reactive power consumed by the inductive load. When the capacitor is connected in parallel at both ends of the load, it will generate a capacitive current in the opposite direction of the load current. This capacitive current will lead the voltage and offset the lagging part in the load current, thereby reducing the phase difference between the total current and voltage and improving the power factor.

The working principle of the electrothermal high-voltage dry parallel capacitor is based on the basic characteristics of capacitance, that is, the capacitor can store electrical energy and release it when needed. In the AC system, the capacitor will continuously charge and discharge, generating capacitive current, which offsets the reactive component in the load current, thereby achieving reactive compensation.
