Abstract: In this paper, a method for GIS equipment fault diagnosis by the analysis of volume fractions of the derivatives of SF6 gas inside GIS equipment is presented. For the method, based on the differential spectra method, a neural network model and the particle swarm optimization are used for training analysis of infrared spectra, to realize the quantitative analysis of specific derivatives.

Power Systems and Products, Mitsubishi Electric Contributing to efficient and stable energy supplies High-voltage Switchgear Mitsubishi Electric gas-insulated switchgear (GIS) and gas circuit breakers (GCB) represent the best of modern technologies.
In an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium. The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure
Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF6) gas to cool and quench the arc on opening a circuit. Advantages
Silicone grease are widely applied in flange connections of gas-insulated switchgear (GIS) providing protection against flange and sealing O-ring corrosion and subsequent SF6 gas leakage. During GIS operation, grease bleeding phenomenon was frequently
