Corona Power Loss-Calculation, Formula, Equation

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 […]

Types of Insulators-Pin Type Insulator, Suspension, Strain, Shackle

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 […]

Electrostatic Precipitator- Construction, Working Principle

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 […]

What is Lightning Arrester-Working Principle Diagram

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 […]

What is Skin Effect? Definition Factors affecting

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 […]

Reactive Power Generation and Compensation,Advantages

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 […]
