Gas-insulated switchgear | Transmission Products | Siemens ... Siemens range of gas-insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept. Since its introduction back in 1968, Siemens has installed switch fields in all climatic zones of the earth, recording over 420,000 years of operation since.
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.
