Gas insulated substation ppt - lvoe.windforlife.it insulated substation ppt, Toshiba's Gas Insulated Transformer (GIT) is the most technologically advanced solution for hydro-power and underground substations, densely populated cities, mission critical substations, and offshore substations. Toshiba GITs are insulated with SF 6 gas rather than traditionally hazardous oil which risks fire, explosions, and contaminating leaks.
Tank Type Vacuum Circuit Breaker (SF6 Gas Insulation ... bushing current transformer (BCT) can be built into the tank. This reduces the footprint space. It does not require the inspection of the breaking part by opening. It can realize the maintenance cost saving. It also reduced the required SF6 gas amount down to about 1/3 compared with that of gas circuit breaker (GCB).
