Have you heard about the shunt trip circuit breaker? How will we draw the shunt trip breaker wiring diagram? We are acquainted with a circuit breaker that protects our power system from unwanted faults such as a short circuit. Electricity is more ferocious than the leopard. A few days back,...

Combined cycle power plant - we can guess its structure from the name. It has two cycles. It produces current by generating coupling of turbine and burning fuel. Also, the heat of the turbine is used for making steam by heating boiler water and the steam is used for the...

We have studied a lot about the motor/generator excitation systems. But have we understood it deeply? Let's discuss the motor and generator excitation system in an interesting way. What is Excitation?  From the word excitation, we can guess that it must be a process for exciting something. Suppose, you have a...

We all are familiar with ammeter and voltmeter. We measure current by ammeter and voltage by a voltmeter. At the time of measurement, the ammeter is connected on series and the voltmeter on parallel. Today we will discuss the conversion of ammeter to voltmeter. Ammeter The internal resistance of the ammeter is...

Do you know What is the function of AVR? Can't concentrate on studying? Sometimes you feel active and sometimes the energy is gone. The cause is a lack of concentration. If a motivator motivates you in this condition and boosts you up it would be great. And when alternator voltage...

Based on tripping quality/breaking capacity, MCB( Miniature Circuit Breaker) can be of different types. Today we will discuss types of MCB circuit breaker. What is tripping quality/breaking capacity?  We can compare this topic with the human body. We know, human blood is a buffer solution. It means, if you eat...

Do you know 3 wire capacitor diagram for the ceiling fan? In this article, we are going to acquaint you with the ceiling fan capacitor wiring diagram. We can connect capacitor with ceiling fan very easily. Before discussing the capacitor wiring diagram I want to make a clear concept...

A ceiling fan is a crying need in our running lives. As electrical engineers, we have to know the ceiling fan speed control switch wiring diagram. In this article, I am going to discuss the ceiling fan speed control switch wiring diagram and simple implementation in our daily lives....

Some of us have a question, Why Capacitor is Used in Ceiling Fan or Single Phase Motor? Maybe for saving charge? Is this a real fact? Let us know about the real facts behind it. Today we will discuss why capacitor is used in ceiling fan? If we say in...

We all heard about relay but we are seeking out a simple relay wiring diagram. It's a very popular topic for all electrical engineering students. Today I will discuss it in an easy manner. Let's start. Before going into details, I want to introduce the relay first. What is relay? Imagine,...

We can do three phase supply by a single-phase transformer banking system. While transformer banking it’s necessary to have the right polarity. Today we will discuss how to do the polarity test of transformer? What is the Transformer Polarity test?  Transformer polarity means the way of the induced voltage in...

Pole and tower aren’t the same things. But do we know what is electric pole and tower? We mistake by thinking they are the same. They have a lot of differences. Let's talk about what is electric pole and tower? What is Electric Pole and Tower and Difference between them Poles Generally,...
