Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, 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.Get price

GIS vs AIS - Substation Earthing

Reduced Ground AreaInduced CurrentsFast Transients Overvoltages and TGPRSummaryNormally, with an AIS, a single uninsulated copper loop laid around the perimeter of the site with cross connections to pick up the individual items of equipment, will provide a sufficiently low resistance electrode. However, the smaller area occupied by a CIS means that the size of the main earth loop will be smaller and therefore the total amount of conducting path will also be smaller. The possible solutions to reduce the earth electrode resistance are (1): 1. High density grid: frequent and short connections from the switchgear elements to the earth grid. This reduces the TGPR in the GIS and contributes to reduce the total earth electrode resistance, but not in direct proportion to the additional length. 2. Connection to the reinforced concrete mat:connecting the reinforcing steel mesh and structural steel to the earth grid will reduce the total earth electrode resistance. However this is complicated and it has to be done in a way that avoids problems of overheating and damage o...Get price
