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…

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…

Critical Disruptive Voltage & Visual Critical Voltage

Critical disruptive voltage is defined as the voltage at which complete disruption of the dielectric strength of air occurs. if the voltage increases above critical disruptive voltage corona occurs.  𝛿: air density correction factor  r: radius of conductor  d: distance of…

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…
