Vacuum circuit breaker is most reliable among other circuit breakers like oil, Air blast or sulphur hexafluoride circuit breaker. In this post we will read about vacuum circuit breaker, its construction and working along with...
Category - protection of power system
In this modern era, Switchgear and protection become a important aspect of power system, as demand of electrical energy has increased very much. Electrical energy is much needed in almost every field and purposes like heating...
In this particular section, we will discuss about fuses, types of fuses and their uses, so lets start with the definition. A fuse is a short piece of metal, inserted in the circuit which melts and breaks the circuit when...
As the name itself suggests that a circuit breaker is used to break the circuit. Now, in this particular post we will see that How it breaks the circuit? When it breaks the circuit?and Why it breaks the circuit?I have also...
Oil circuit breakers are very important part of power system, they are responsible to make the system healthy. The classification of circuit breaker is based on the medium which is used to quench the arc. In this section we...
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...
