GPU-2000: WIKA's Solution for Comprehensive SF6 Gas ... hexafluoride is widely used as an insulating gas and arc quencher in electrical equipment. However, to maintain its effectiveness, SF 6 needs regular cleaning to get rid of harmful impurities. Handling also needs to be done with care, as SF 6 is a potent greenhouse gas if it escapes into the atmosphere. WIKA's GPU-2000 all-in-one solution allows safe and efficient SF 6 gas handling ...
Circuit breaker - Wikipedia circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume ...
