In the field of electrical and power distribution engineering, there are two important concepts namely neutral and floating neutral. The neutral, also called neutral wire, is a return path for electric current in electrical circuits that balances the phase loads and serves as a reference point. In practical applications, the neutral is typically grounded at the main panel or distribution end. On the other hand, the floating neutral is also a neutral wire but it is isolated from the ground terminal. The concept of floating neutral is not much common in practical applications, but it may be used in ... Read More
Introduction One billion can be written as 1 , 000 , 000 , 000 . In mathematics, place value can be used to define numbers. There are two different ways to represent the place value of the digits in the numbers. The positional values of the number are determined using place value charts. Positions allow for the expansion of the numbers in the general form. In this tutorial, we will learn about billions in rupees, the number system, and the conversion of the number system. Number Systems Number systems are mathematical expressions of numbers in various ways that computers ... Read More
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 More
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 More
An inverter battery is an electrochemical device that is used for storing electrical energy. It is a type of rechargeable battery that works with an inverter to provide continuous power supply in the case of main supply outages. An inverter battery charges when main power supply is available and it delivers the stored electrical power when the main power supply is disrupted. In this article, we will explain the different types of inverter batteries along with their advantages and disadvantages. But before that let us get an overview of inverter batteries and know about their specifications. What is ... Read More
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 ... Read More
An energy meter is a device used for measuring the amount of electrical energy consumed by a load over a certain period of time. This device is essential for recording the electricity usages so that consumers can monitor and change the energy consumption patterns to reduce energy consumption and hence the bill amount. An energy meter is an important link between power supplier and consumers that allows them for efficient measurement of electricity supplied or consumed. What is an Energy Meter? An electrical device or instrument which is used for measuring the amount of electricity consumed by the consumers over ... Read More
In electrical power system, there is a device called Automatic Voltage Regulator (AVR) used to adjust the voltage levels within a desired limit. In other words, an automatic voltage regulator is an electronic circuit that is primarily used for regulating the output voltage of an electric generator, so that we can obtain a constant voltage even when the load is fluctuating. This tutorial will explain the construction, working, needs, advantages, and applications of automatic voltage regulators (AVRs). So, let’s start with the basic introduction of automatic voltage regulator. What is an Automatic Voltage Regulator? An AVR or Automatic Voltage Regulator ... Read More
In an electrical system, there are three types of conductors used, they are phase, neutral, and ground. In general, the neutral wire is grounded for safety and stability reasons. But sometimes, a condition occurs where the neutral wire of the systems is disconnected from the ground terminal, this condition is known as floating neutral. In some special situations, the neutral wire is intentionally left isolated from the ground terminal, this is also known as floating neutral. In this article, we will learn about floating neutral in electrical systems, its effects, causes, and methods of testing and fixing the floating ... Read More
Introduction A chord is a line segment connecting any two points located on the circumference of the circle . The circle is a well-known two-dimensional shape used in Euclidean geometry. It has various components, including chord, radius, diameter, etc. In this tutorial, we will discuss the definition, formulae, and some theorems related to the chord of a circle. Circles The circle is a two-dimensional figure drawn on a plane in such a way that each point on the circle is equidistant to a fixed point. The fixed point is known as the center of the circle. The dimension of ... Read More
