  • Gas-Insulated Substations - GIS

    6 mins readNov 10, 2010A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures. Gas-Insulated Substations – GIS

  • The SF6 Decomposition Mechanism: Background and

    Jan 24, 2017Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases.Cited by: 1

  • Gas Insulated Substations | Advantages

    3 mins readNov 04, 2017In Gas Insulated Substations all the switching electrical equipment such as circuit breakers, isolators, earth switches, and busbars are completely enclosed inside modules which are filled with SF 6 gas. These modules are factory made and site assembled. Hence takes very little time for commissioning compared to air-insulated substations.
