2017-11-3LPG Leakage Detection Circuit Breaker. using RF Module Introduction. Background of the Study The LPG which is otherwise known as Liquefied Petroleum Gas, has many industrial as well as domestic uses. It is finding wide range in homes as what we know as cooking fuel. LPG gas is a combination of propane and butane.

2021-2-20SF6 circuit breaker is an extinguisher that uses sulfur hexafluoride gas to cool and quench the arc. It is the type of circuit breaker used to protect electrical grids, power stations, and distribution systems.. Sulfur hexafluoride gas has strong electronegativity and insulating properties, making them a better option than air and oil circuit breakers.
