## Comparison of SVC and STATCOM

Introduction: SVC and STATCOM are two types of FACTS devices that can provide dynamic reactive power compensation and voltage support for power systems. SVC and STATCOM have similar objectives and functions, but they have different structures and principles, which result in different features and characteristics. Therefore, it is important to understand the differences and similarities […]

## What Is Negative Sequence Current, And Why Does It Matter?

If you’re in the power industry, then you’ve likely heard of negative sequence currents. But what exactly is it, and why does it matter? In this article, we’ll break down the basics of negative sequence current and explain why it’s important for the power industry. What Is Negative Sequence Current? Negative Sequence Current is a

## Harmonics in Power System: generation and hazards of Harmonics.

The root cause of harmonic generation in power systems is non-linear loads. When the current flows through the load, it does not have a linear relationship with the applied voltage, and a non-sinusoidal current is formed, thereby generating harmonics. The harmonic frequency is an integer multiple of the fundamental frequency. According to the analysis principle

## Precautions During Installing Series Reactors

Series reactors are primarily employed for current limitation and impedance enhancement. Some of the functions they serve include current limiting and neutral/earthing as well as motor starting and arc furnace series reactors. They can also be used in a duplex reactor configuration. Below we have discussed what are the precautions to be taken during the

## What is the Function of the Reactor? The Working Principle of the Reactor

What is a reactor Usually, the resistance of capacitance and inductance to AC in the circuit can be called reactance, and the symbol is represented by X. What is a reactor? Some people in the industry also call it an inductor. When a conductor is energized, it will cause a magnetic field in a certain space it

## The Difference Between Reactor and Filter

Introduction to Reactor 　　Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field within a specific range of space occupied by it, so all current-carrying electrical conductors are inductive in a general sense. But the inductance of an energized long straight conductor is small, and the magnetic field it creates

## The difference between DC reactor and AC reactor

AC reactors are used in AC circuits, including three-phase AC reactors and single-phase AC reactors. On the other hand, the DC reactor is used in the DC system circuit, only single-phase. The DC reactor, also known as the DC smoothing reactor, is used for the DC side of the converter. The DC current with the AC component
