Electrical test equipment application solutions from Megger

Sulfr hexafluoride: Sulfr hexafluoride insulated circuit breakers are the main type of breaker installed in transmission networks today and the only current style of breaker being manufactured for EHV applications. Sulphur hexafluoride (gaz sf6) is an inert, heavy gas with good dielectric and arc extinguishing properties. The dielectric strength of the gas increases with pressure. CAUTION must be exercised when handling the gas however because, although sf6 gas is in itself an inert gas, it will produce corrosive by-products
