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…
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…
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…
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…
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…
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…
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…
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…
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…
What is a Lightning Strike and the Phenomenon of lightning Lightning has been a source of curiosity for humans for thousands of years. lightning is a discharge of electrical charge between cloud and ground, the height of the cloud above ground…
