An MCB or Miniature Circuit Breaker is a type of circuit breaker or an automatic electric switch used to provide protection against different types of electric faults like short-circuit, overcurrent, overload, etc. Therefore, MCB is considered an electrical protection device. MCBs are primarily used in low-voltage electrical circuits like house ... Read More

A power system is an interconnected network of electrical components such as alternators, transformers, transmission and distribution lines, and electrical loads. Each of these components are sensitive to different types of faults or abnormal conditions. For example, a transformer can burn due to overloading or short-circuit. Therefore, it is desirable ...

A protective relay is an electrical switch which can automatically operate when a fault or any other abnormal conditions occur in the electrical system. It sends a signal to turn on the alarm or indicator or trip a circuit breaker to separate the faulty part from the healthy section. The ... Read More

In the field of electrical engineering and power systems, a fault is an abnormal condition that can result in damages to the circuit. Hence, a fault is nothing but a defect in the power system. When a fault occurs in a power system, we need a "power system protection" scheme ... Read More

The main difference between primary protection and backup protection is in their functionality. Primary Protection is provided to quickly detect the fault and isolate the faulty section from the healthy part, while Backup Protection is provided to isolate the faulty and healthy parts if the primary protection fails. In this ... Read More

Resistance, inductance, and capacitance are three main parameters of an electric circuit. Resistance is defined as the measure of opposition in the flow of electric current. Inductance is defined as the measure of opposition in change in the direction and magnitude of the current. Whereas, capacitance is defined as the ... Read More

Cathode Ray Oscilloscope (CRO) is an electronic device used for testing, research, and design applications. It is a device that helps us to display and analyze the electrical signals in the form of waveforms. In the field of electrical and electronics engineering, CRO is used to perform numerous operations like ... Read More

A circuit breaker is a switchgear device used in electrical system to interrupt the flow of electric current in the circuit. It is used for either switching or protection purposes. In this article, we will learn about circuit breakers, their types, characteristics, standard ratings, and applications. So, let’s start with ... Read More

Monocrystalline solar panels are one of the most popular types of solar panel available in the market and is used for generating electricity from sunlight. The primary reason behind its popularity is its relatively high efficiency in all weather conditions. Although it is a relatively expensive solar panel than other ... Read More

The increasing demand of electricity cannot be met through conventional ways of generating electricity. To fulfil the electricity demand, several new methods have been developed. Solar panels are one of the most common of them. A solar panel is a semiconductor device that can convert sunlight into electricity. This light ... Read More
