sf6 o2 check for leaks for 132kv

SF6 is non-flammable, inert and has high chemical and thermal stability. For humans, SF6 is not dangerous when handled correctly, e.g. according to the IEC 62271-4 standard [51]. SF6 gas-insulated, high-voltage equipment was first built in the 1960s in the USA and later in Europe.
