What is a Circuit Breaker? Vacuum circuit breaker working function
What is a circuit breaker?
A circuit breaker is an electrical device that is used to interrupt electrical power. A circuit breaker is like a heavy switch that is used to switch on and off heavy electrical power. A special arrangement is made to quench the arc produced between switching contacts during circuit interruption. For the purpose of arc quenching, air, sf6 gas, or vacuum is used in the circuit breaker.
Types of circuit breaker
A circuit breaker is categorized in many ways. Different types of circuit breakers are used according to needs and requirements.
Circuit breaker types according to voltage
LV circuit breaker
LV circuit breaker is used on low voltage to interrupt electrical power. Air is normally used as arc quenching media in such kind of circuit breakers.
MV circuit breaker
MV circuit breakers are used to interrupt medium voltage in industry and power distribution substations. Vacuum and oil are used as arc quenching media in such kind of circuit breakers.
HV circuit breaker
HV circuit breakers are used to interrupt very high voltage power. SF6 gas is used as quenching media in such kind of circuit breakers.
Parts of Circuit breaker
There are many parts of a circuit breaker. A circuit breaker is a piece of complex electrical equipment having many parts like contacts, springs, levers, hinges, and many other parts. The following diagram shows common parts for a circuit breaker.

3 phase power and 3 phase power generator
3 phase power and 3 phase power generator
3 phase power generator
3 phase power generator is a machine which generates 3 phase ac power. AC power is of two types. One is single phase and the other is multi phase. 3 phase is example of multi phase power which is very commonly used due to its special characteristics and powerful nature over single phase ac power. 3 phase power is generated in the same way as single phase power is generated. Only difference is the construction of 3 phase ac power generator. There are three seperate windings 120 degree apart each other. In a 3 phase power generator 3 windings are places 120° apart to make a complete machine having 3 separate windings in total of 360°.
