Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
TRANSFORMER OIL AND IT'S INSULATING PROPERTIES are two main causes of gas formation within an operating transformer- I) electrical disturbances and ii) thermal decomposition. Actually the breakdown of electrical insulating materials and related components inside a transformer generates gases within the transformer. The major gas produced is Hydrogen. The minor gas produced is Methane.
