Electric Portal is about electrical concepts and other electrical machines like motor transformer,dol starter,star delta starter,auto transformer starter and much more
When the potential difference between two conductors of a transmission line is raised beyond a certain limit, a point is reached when a violet glow appears around the conductor surface with a hissing noise and ozone gas smell this phenomenon is called Corona. Power loss due to the corona effect is called corona power loss […]
WHAT IS AN ELECTRICAL LOAD? An electrical load on a power system is any electrical appliance that consumes electrical energy and converts it into heat or in other forms. Different electrical devices use electrical power to convert it into another form. For example, Types Of Electrical Loads used in day-to-day activities are resistive loads which […]
Types of insulators are used in an overhead transmission and distribution line to provide insulation to power conductors from the ground and tower or supporting structure. like Pin type of insulators, Suspension, and Strain type insulators. There are 5 types of insulators used in transmission lines as overhead insulation Generally, insulators are connected to cross an arm […]
Classification of power system Buses In the power system, every bus is associated with four different quantities, real power, reactive power, bus voltage, and phase angle. In load flow, two parameters out of the four are specified and the remaining two need to be calculated through the solution of equations. Depending upon the quantity that have […]
What is the Corona Effect in transmission lines? Corona effect (also known as Corona Discharge) is nothing but the ionization of air around the power conductor. The air around the power conductor has free electrons due to radioactivity and cosmic rays. As the potential between conductors increases potential gradient near to conductor surface increases. When the […]
Electrostatic Precipitator also known as ESP is the leading and most effective technology used for removing solid dust particles from industrial flue gases. The electrostatic Precipitator consists of a large steel chamber and inside the chamber, an electrode system is installed. Gases generated due to the combustion of pulverized fuel contain solid dust particles. When […]
There are different types of lightning arresters like Rod Gap Arrester, Horn Gap Arrester, Valve type, and expulsion type and they differ from each other only in construction details. but they operate on the same principle which is to provide a low resistance path for surges to the ground. Types of lightning Arresters Rod Gap […]
Grounding wire running over the tower or substation provides good protection to the electrical system against direct lightning stroke but they fail to provide protection against traveling high voltage or current waves that reach to terminal equipment. The lightning arrester or surge arresters provide protection against such waves. Lightning Arrester The above diagram shows the […]
Definition: The non-uniform distribution of current through the given cross-section area of the conductor, when it operated on AC current is known as the Skin Effect. When DC current flows through the conductor it is distributed uniformly throughout the cross-section area of the conductor or skin. However, an alternating current flowing through the conductor does not […]
Some methods of reactive power generation, compansation and advantages of reactive power generation are describe below • synchronous alternators; • synchronous compensators (SC) • static var compensators (SVC) Reactive power using synchronous alternators Synchronous alternators are the main machines used for the generation of electrical energy. They are intended to supply electrical power to […]
