The Top 25 Gas Insulated Substation (GIS) Companies Gas Insulated Substation (GIS) is a compact assembly consisting of multiple components enclosed in a metallic covering with compressed sulphur hexafluoride (SF6) gas as an insulating medium. The concept of the gas insulated substation was introduced in 1920 when oil was used as the insulating medium in the system.

Dissolved Gas Analysis of Transformer Oil | Electrical4U· Dissolved gas analysis (DGA) is the study of dissolved gases in transformer oil.It is also referred to as a DGA test. Whenever a transformer undergoes abnormal thermal and electrical stresses, certain gases are produced due to the decomposition of the transformer oil. When the fault is major, the production of decomposed gases are significant and they get collected in a Buchholz relay.
