SF6 circuit breaker uses SF6 (Sulfur Hexafluoride) gas as an air quenching medium. This gas is electro-negative and it has high dielectric strength to absorb free electrons. This is very effective for high voltage applications […]
Air break circuit breaker uses atmospheric pressure in air as an air quenching medium. This type of circuit breaker employs a high resistance interruption principle. The arc runners and chutes increase the arc length. Moreover, […]
What is Air Blast Circuit Breaker? In this Air blast circuit breaker, it uses a high-pressure air as the arc quenching medium. In this type of circuit breaker when the contacts are separated, high-pressure air […]
What is an Oil Circuit Breaker? The oil circuit breaker has an insulating oil which is used as an arc quenching medium for arc extinction. Oil has better insulating property than air. It consists of […]
The vacuum circuit breaker (also known as vacuum interrupter or VCB) uses the arc quenching process in the vacuum as a switching medium. The vacuum has the highest insulating strength. So, it has far superior […]
The fuse and circuit breaker are circuit protection devices used to protect the system from over-current conditions in power system industries. Both do the same but differs from their various characteristics and working principle. Let’s […]
By definition, a Circuit breaker is a mechanical device that isolates the faulty system from a healthy system of the power system by opening or closing the circuit. There are different types of circuit breakers […]
Relay is an electromechanical switching device most widely used in the automotive and telecommunication industries. It can be found in cars, washing machines, medical equipment, aircraft, etc. We can see that relays are being used […]
