What is a Buchholz Relay? Working Principle

The Buchholz relay is used to detect internal faults in an oil-filled transformer and it works on the theory of gas detection.

In this post, we will learn the effect of the long distance cables between VFD and motor, and why it must be avoided.

A transformer bushing is an electrical insulator that allows the safe passage of electrical conductor current.

An auto changeover switch is used to automatically switch the electrical power between primary and secondary sources.

In this post, we will learn the types of conductors used in overhead cables. An electrical wire has two parts – conductor and insulator.

In this post, we will learn about the most common types of industrial circuit breakers and their principle of operation.

We will learn the various terms and concepts related to an electrical motor like service, torque, horsepower, overload, cooling, speed, slip.

In this post, we will learn the various types of relays used in an air circuit breaker (ACB).

In this post, we will learn the difference between permittivity and permeability.

In this post, we will learn the importance of neutral wire in electrical circuits.
