HV Substations - Mitsubishi Electric

Mitsubishi Electric began its industry leadership in Gas Insulated Switchgear (GIS) by building its first product in 1968. In 1973, it installed the first 500kV hybrid gas-insulated substation. Three years later Mitsubishi Electric constructed the world’s first 550kV fully gas-insulated switchyard at the Ohi Nuclear Power Station, which is the largest nuclear power plant in Japan.Get price

Where Innovation Meets the Road | TD World

Emergency PreparednessViability and ReliabilityA Team EffortLeading-Edge TechnologyLessons LearnedFuture ApplicationsDominion Energy purchased the mobile substation as part of its resiliency strategy for responding to cyber-attacks, physical breaches, extreme weather and other such events. With hurricanes posing a real threat to the area, the mobile substation is a valuable asset. It allows the utility to re-establish service within seven days of an incident inside existing substations. Depending on the circumstances, without the mobile substation, the complete loss of a substation transmission transformer could take two months or more from which to recover. The Bremo-Cartersville rebuild project presented the perfect opportunity for using the mobile substation. The project saw the installation of the mobile substation adjacent to the Cartersville substation. It provided the opportunity to vet procedures and associated checklists, as well as to test equipment. With the butterfly doors open on the 115-kV mobile GIS trailer, the GIS breaker, disconnects and ground switches can be seen. In this trail...Get price
