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.
Why Measure Hydrogen Gas in Transformer Oil | Qualitrol Corp Furan analysis is recommended every 2 years; Dielectric Breakdown Voltage every 1 year. The exception to this is Dissolved Gas Analysis. For Dissolved Gas Analysis, the recommendation is that as conditions progress the frequency of measurement should be increased from annual testing all the way up to daily [IEEE Standard C57-104-2019_pg 87]
