SF6 decomposition Monitor for middle voltages

SF6 decomposition Monitor for middle voltages

2020-11-30Although SF6 is non-toxic and non-flammable on its own, when used as a circuit-interrupting medium it can produce a number of dangerous and toxic decomposition products. This calls for special precautions when working on any SF6-filled equipment. Even more serious is the issue of disposal at the end of
