gis substation leak MAINTENANCE AND TESTING in Indonesia

A GIS results in the lower overall project cost GIS is the more economical solution. GIS has all live parts contained in SF6 gas-light enclosures. The bus bars are physically arranged in trefoil formation largely to cancel out the resultant stray magnetic field and any associated enclosure eddy current losses.

  • 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 sf6 gas 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.
