SF6 circuit breaker maintenance | T&D Guardian Articles | USA first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.
Gas detector relays type GDR - Hitachi ABB Power Grids GDR™ is a gas detector relay that provides an early indication of faults occurring in oil-filled conservator type power transformers. The GDR provides alarms under two types of transformer fault conditions: faults of an incipient or minor nature resulting in a slow evolution of gas or faults of a major nature that generate a sudden pressure wave.

Corona discharge - Wikipedia corona discharge is a process by which a current flows from an electrode with a high potential into a neutral fluid, usually air, by ionizing that fluid so as to create a region of plasma around the electrode. The ions generated eventually pass the charge to nearby areas of lower potential, or recombine to form neutral gas molecules.. When the potential gradient (electric field) is large ...
