Protective Relays and Their Functional Characteristics
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 primary function of a protective relay in an electrical circuit or system is to sense the fault and initiate the operation of a circuit breaker to which it is connected. A protective relay is one of the most important components of an electrical protection system, as it is entirely ...
Read MoreFaults in Electrical Power Systems – Causes and Effects
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 that can isolate the faulty part from the healthy part. In this article, we will learn about basic definition of a fault in power system, its main causes and effects. So, let’s get started with the basic definition of the electrical fault in power system. What is a Fault in ...
Read MoreDifference between Primary Protection and Backup Protection
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 article, we will discuss in detail about the primary and backup protections used in power systems along with the major differences between them. So, let’s begin with a basic introduction of primary and secondary protections. What is Primary Protection? Primary protection is defined as the initial layer of protection ...
Read MoreFactors affecting Resistance, Inductance, and Capacitance
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 measure of opposition in change in the voltage. The resistance, inductance, and capacitance of a conductor depend on several factors like temperature, length, cross-sectional area, etc. In this article, we will discuss about all these factors affecting the resistance, inductance, and capacitance of a conductor. What is Resistance? In electrical ...
Read MoreCircuit Breaker - Working, Types, and Standard Ratings
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 the basics of circuit breaker. What is a Circuit Breaker? A circuit breaker is an automatic electrical switching device used in power system to interrupt the current in case of faults or abnormal conditions. A circuit breaker is similar to a normal electrical switch but it can also perform switching ...
Read MoreWhat are Monocrystalline Solar Panels?
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 types of solar panels. In this article, I will explain all the important concepts of the monocrystalline solar panel, such as its construction, advantages, disadvantages, and applications. So, let’s start with the basic introduction of the monocrystalline solar cell which is its fundamental building block. What is a ...
Read MoreHow to Choose Solar Panel for Home?
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 to electricity conversion is based on the principle of photovoltaic effect. Thus, solar panels are also known as photovoltaic systems. In a solar panel, there are multiple PV or solar cells used that absorb the sunlight and produce electricity. This electricity is stored in rechargeable batteries and supplied as per ...
Read MoreSingle-line and Multiline Diagrams to Represent Electrical Systems
This article is meant for explaining the two most widely used visual representations of electrical systems also called electrical diagrams. These diagrams are single-line diagram and multiline diagram. These two diagrams are used in electrical engineering to represent various electrical layouts and connection arrangements of electrical systems. In electrical engineering, the visual/graphical representation of electrical systems like distribution systems, control panels, transmission line, generating stations, etc. is very important to understand the connections of various system components, designing and analyzing electrical systems, and more. In the field of electrical engineering, the following two main types of visual representations are ...
Read MoreSmart Meters – Advantages and Disadvantages
A smart meter is an electrical instrument used for measuring electrical energy consumed and other electrical parameters of the electricity supply system. It is basically a type of energy meter equipped with more advanced metering technologies. The main advantage of using a smart meter is that it does not require any manual reading system for billing and other purposes. Instead, it can automatically send the data through communication channels to the electricity company. Therefore, smart meters help in reducing the operational cost and time. In this article, we will explain the major advantages and disadvantages of smart meters. Before ...
Read MoreTypes of Electric Vehicles – BEV, HEV, PHEV, and FCEV
This article is meant for explaining different types of electric vehicles, their construction, components, working principle, and features. A type of vehicle, a car, or a bike, or any other, that uses electricity as the source of energy to run is called an electric vehicle. Today, electric vehicles are becoming one of the most popular modes of transportation because of their sustainability, low operating cost, and eco-friendliness. Traditional vehicles operating on petrol and diesel have very high operating cost and they also pollute the environment due to emissions. Till date, several different types of electric vehicles have been ...
