Introduction Air blast circuit breaker is used to interrupt heavy currents and for the extinction of arc with the help of blast of air. Air blast circuit breakers employ high pressure air blast as an arc quenching medium...
In a SF6 circuit breaker, the SF6 gas is used as an arc quenching medium. SF6 gas or sulphur hexafluoride gas has one atom of sulphur and six atoms of fluorine. The physical and chemical properties of the gas are listed...
A Relay is a sensing device, which is used to sense the faults in the system. If any fault occurs in the system then the relay will send the signal to the circuit breaker to trip the circuit. The same concept applies with the...
