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 terminal equipment. The lightning arrester or…

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…

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…

TNC Switch Working and Function

TNC switch stands for Trip Neutral and Close. TNC switch has three positions and it is used to operate the circuit breaker locally. TNC Diagram In this article, we will discuss the working purpose and function of TNC in electrical…

Suspension Type Insulator and advantages

Electrical Insulators are used in an overhead line to provide insulation to power conductor from ground and tower or supporting structure. Generally, insulators are connected to cross arm of supporting structure and power conductor pass through the clamp of the insulator. In this…
