Gas Insulated Substations. A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible. The clearance required for phase to phase and phase to ground for all equipment is much lower than that required in an air insulated substation ...

  • Major components you can spot while looking at HV/EHV GIS

    Apr 06, 2021 · Gas-insulated switchgear (GIS) is a piece of high voltage equipment that is being constantly developed day by day. The basics of GIS technology is more or less the same, but everything else under the hood is improved a lot comparing to just a few years ago. This article explains major GIS components and their characteristics.

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, gaz 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 Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.

  • Study of gas insulated substation and its comparison with air

    Feb 01, 2014 · Two possible transformer failure modes may happen in GIS: (i) The transformer main insulation (the insulation between HV winding and LV winding, HV winding and core, or HV windings) will be threatened because of the large magnitude of the switching and lightning surges (ii) the insulation between turns at the beginning of the HV winding is often disproportionally more stressed because of the large potential gradient appearing in the initial voltage distribution.
