Gas insulated switchgear is a metal closed type switchgear that acts as an insulator between live parts and soil metal casing with sulfur hexafluoride (SF6) gas. High voltage equipment is housed in a gas tight container filled with a degassing gas called SF6.
In a vacuum circuit breaker, the arc interruption takes place in vacuum. This technology has been found to be most suitable for medium voltage application
A circuit breaker in which the contacts open and close in sulfur hexafluoride (SF6) gas is known as an SF6 gas circuit breaker. These circuit breaker
This air blast circuit breaker has been used earlier for open terminal HV application, for system voltages of 245 kV, and 400 kV up to 765 kV
A circuit breaker in which the contacts open and close in air at atmospheric pressure is defined as an air circuit breaker. Air circuit breaker is an
These minimum oil circuit breakers utilize oil as the interrupting media. However, unlike bulk oil circuit breakers, these designs place the interrupting
What is called Bulk Oil Circuit Breakers? The circuit breakers in which the contacts part in oil and wherein the oil also provides the main insulation
This article covers various technological aspects related to circuit breakers. The arc phenomenon which is common to all circuit breakers,
Miniature Circuit Breaker is the full form of MCB. It is used for tripping purpose while circuit connection in overload or short circuit situation
