What Components and Modules Does Capacitor Reactive Compensation Contain?

 I. Introduction

I. Introduction

In the realm of electrical engineering, reactive power plays a crucial role in the efficient operation of power systems. Reactive power, unlike active power, does not perform any useful work but is essential for maintaining voltage levels that allow active power to do its job. Capacitor reactive compensation is a technique used to manage reactive power, improve power factor, and enhance the overall efficiency of electrical systems. This article aims to explore the components and modules that constitute capacitor reactive compensation systems, shedding light on their functionality, benefits, and challenges.

II. Understanding Reactive Power

A. Explanation of Reactive Power

Reactive power is the power that oscillates between the source and the load in an AC system. It is measured in volt-amperes reactive (VAR) and is primarily associated with inductive loads such as motors and transformers. While active power (measured in watts) performs actual work, reactive power is necessary for creating magnetic fields in inductive devices.
