SF Maintenance Equipment Fundamentals

Compared with older oil-based technology, GIE has far longer maintenance cycles – often times 10 years or more. Over time, moisture and decomposition levels increase and must be kept within industry-recognized limits. Testing and benchmarking these levels will provide the user with a means of scheduling gas maintenance. Decomposition DetectorGet price

Sulfur hexafluoride circuit breaker - Wikipedia

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, insulating gas circuit breakers are widGet price
