Measuring partial discharge in GIS - Think Grid

Jun 06, 2012 · To overcome this constraint, a parallel technology was developed, the Gas-Insulated Substation (GIS), using a gas, for example sulphur hexafluoride (SF 6), at high pressure. SF 6 has excellent dielectric properties and is used as the insulating medium between the phases and between the phases and earth. As a consequence, a GIS is much more compact.Get price

Gas-insulated Switchgear (GIS) Testing - OMICRON

Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (sf 6) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS.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
