GIS compact dimensions and design make it possible to install substations up to 550kV right in the middle of load centers of urban or industrial areas. GIS is also adopted when substation is to be installed at very high altitudes or very lo w temperatures or seismic considerations and hydro station.
GIS is also considered for severe environment condition, where saline pollution near coastal areas of industrial pollution requiring regular cleaning of insulators and corrosion of metallic components and electrical joints. All these factors in totality make GIS one of the attractive equipment options to adopt. In fa ct qu al it y consciousness of equipment alone makes GIS as favored equipment choice for remote operation.

Indoor and underground GIS is possi ble even in urban and highl y pop ulat ed areas whic h wil l all ow buildi ng of the subst ation at the point of consum ption which will bring about signific ant cost savings in the dis tri but ion net wor k. If the substation is connected to overhead lines, then space will have to be allocated for tower and droppers which might reduce the total land saving. The land area required for a GIS is in the order of 10% to 20% of that for an AIS 9(Air Insulated Switchgear) substation considering the switchgear bay, the saving in overall land area depends very much on the specific voltage level and the connection to transformers, reactors and incoming and outgoing lines. It has excellent adaptability in meeting most difficult terrain or space constraints. GIS internationally is getting acceptance on account of technical merits. The application therefore should be carefully done in case the ambient temperature happens to go below this temperature.

The preparation of manual on GIS is an attempt in this direction it will prove be a guide/recommendatory document for the power station utilities in the country.Ĭ. A manual on GIS will certainly help the users to understand a brief of GIS regarding the details of inside components of GIS, its installation process and operation and maintenance of GIS. However in case of any fault the services of manufacture’s representatives are required to attend and repair the fault since all the modules of GIS comes directly under assembled form and in sealed condition from factory since no technical expertise is available indigenously for repair and maintenance of GIS.

GIS is considered trouble free and maintenance free installation. More over adopt ion of GIS offers an excell ent solution for envir onment al protection since it helps in protecting the system from hazards.

Since all live parts of GIS are contained in a metal enclosure, they are fully protected against environmental effects, such as salt deposits in coastal regions, sand storms, humidity in the atmosphere, etc. Due to the inherent safety and compact layout of a Gas insulated substation, it is the best solution for substations which are to be bui lt in restricted underground spaces. Precisely speaking GIS leads to an effective use of a limited space. in densely populated areas, for aesthetic town planning or under severe environmental impacts. The GIS offers economic solutions for complex switchgear applications, e.g.
