Difference between AB Switch and Isolator
In electrical power systems, different types of switchgear devices are used such as circuit breakers, AB switches, isolators for switching and protection purposes. These switching devices play an important role in power systems. There are two common types of switch devices used in electrical power systems are AB Switch (Air Break Switch) and Isolator. Although, the primary purpose of both AB switch and isolator is similar, but they are completely from each other in construction, operation, and many other aspects. For an electrical engineer, it is very essential to understand the differences between AB switch and isolators to design ...
Read MoreResidual Current Circuit Breaker (RCCB) - How It Works
Residual Current Circuit Breaker (RCCB) is a type of circuit breaker used in electrical circuits for protection purposes. The primary function of an RCCB is to detect a leakage in the circuit current. If there is any leakage in the current, the RCCB can interrupt the circuit and prevent the fault to be happened. Read this article to understand the functions, working principle, advantages, and applications of RCCB. What is an RCCB? RCCB (Residual Current Circuit Breaker) is a protecting device that detects any leakage current in the circuit and interrupt the circuit current. When a fault occurs in ...
Read MoreDifference between Indoor and Outdoor Substations
An indoor substation is one in which the entire substation is built inside a building, whereas an outdoor substation is a substation in which the equipment are installed in an open environment. Read this article to understand all the important differences between indoor and outdoor substations. Let us start this article with a brief overview on electrical substations, indoor substations, and output substations. What is a Substation? A substation or electrical substation is an arrangement of electrical equipment for changing the voltage levels of electric supply for transmission, distribution, and utilization purposes. Basically, a substation is used for the following ...
Read MoreTypes of Power Plants – Advantages and Disadvantages
A power plant is a systematic arrangement of electrical equipment used for producing electrical power. In other words, an industrial facility used for producing bulk amount of electric power is called a power plant. Power plant is also called generating station or power station. These power plants are connected to an electrical network, called grid or power grid. A typical power plant contains many electrical and mechanical equipment such as prime mover or turbine, alternators, transformers, circuit breakers, conductors, etc. A source of energy like steam/flowing water is used to rotate the prime mover that in turn drives the alternator ...
Read MoreElectrical Substation – Types and Components
In electrical power systems, electric power is generated, transmitted, and distributed in the form of alternating current. The electrical power is generated at a power generating station which is located far away from the consumer's load. The generated power is then transmitted and distributed through an electrical network to the load ends. But it is also important to note that power is generated at a lower voltage, transmitted at a higher voltage, and distributed at a lower voltage again. This voltage variation is for many technical and economic reasons. For changing this voltage at many locations in the power system, ...
Read MoreDifference between AIS and GIS Substation
AIS and GIS are the two most widely used switchgear technology in the field of electrical substations. AIS stands for Air Insulated Switchgear and GIS stands for Gas Insulated Switchgear. A substation in which the insulation between phases is provided by the atmospheric air is called an air insulated substation or AIS substation. On the other hand, a substation in which the insulation within phase and between phases is provided by SF6 gas is known as a gas insulated substation or GIS substation. The primary difference between AIS substation and GIS substation is that an AIS substation uses the atmospheric ...
Read MoreTypes of Oil Circuit Breakers (OCBs)
Oil circuit breakers (OCBs) are used for performing the following two important functions - Switching of electric supply Protection of electrical system They are called oil circuit breakers because in this type of circuit breakers, insulating/dielectric oil is used for quenching the arc. In this article, we will learn about the basics of oil circuit breakers and their different types. What is an Oil Circuit Breaker? An oil circuit breaker is an electrical switch in which an insulating or dielectric oil is used for arc quenching. As we know, when a fault occurs in the electrical system, we ...
Read MoreHow Does an Electrical Relay Work?
In electrical engineering, a relay is an electromagnetic or an electronic switch that can automatically operate if any abnormal conditions occur in the circuit. The primary functions of a relay are to monitor the circuit, sense the fault, and initiate the tripping of the circuit if a fault occurs in the system. Read this article to learn the operation of a relay. Let's start with some frequently used terms related to the operation of a relay. Relay Operation Terminology The following are some key terms related to the operation of a relay in power system. Operating Force or Torque - ...
Read MoreMCB (Miniature Circuit Breaker) Types and Applications
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 wiring, commercial wiring, etc. They are not commonly used in high-voltage industrial applications. The main function of an MCB is to protect an electric circuit from damages due to flow of excessive current. This article is meant for explaining the following major concepts related to MCB (Miniature Circuit Breaker) ...
Read MorePower System Protection – Components and Importance
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 to implement such systems that can protect these highly expensive electrical equipment from damage. This practice of implementing protection systems for power system or its components is referred to as power system protection. In this article, we will explain in detail the components, important terms, and the importance of power ...
