Role of Buchholz relay in transformer Protection system | 2018· While using power transformer if any slow-developing faults (insulation failure of windings, core heating, fall of oil level due to leakage etc) arise, the oil present in the transformer is decomposed due to heat. This decomposition of oil produces gases in which more than 70% is hydrogen gas.

GIS or Gas Insulated Switchgear | Electrical4U· SF 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas SF 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar. As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only SF 6 is used both for interruption medium and insulation.
