CEB: GIS SUBSTATION

Previous CEB substations are Air-Insulated Substation (AIS) types which use atmospheric air insulation. A GIS uses a superior dielectric gas, insulating gas, at moderate pressure for insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are housed in Sulfr hexafluoride gas metal enclosures.Get price

Geographic information system - Wikipedia

History and DevelopmentTechniques and TechnologySpatial Analysis with GISApplicationsSemanticsImplications of GIS on SocietyFurther ReadingThe phrase, "geographic information system", was coined by Roger Tomlinson in 1968, when he published the scientific paper, "A Geographic Information System for Regional Planning". Tomlinson, acknowledged as the "father of GIS", is credited with enabling the first computerized–GIS to be created through his work on the Canada Geographic Information Systemin 1963. Ultimately, Tomlinson created a framework for a database that was capable of storing and analyzing huge amounts of data; leading to the Canadian government being able to implement its National Land-Use Management Program. One of the first known instances in which spatial analysis was used, came from the field of epidemiology in the, "Rapport sur la marche et les effets du choléra dans Paris et le département de la Seine" (1832). French geographer and cartographer, Charles Picquet, created a map outlining the forty-eight Districts in Paris, using halftone color gradients, to provide a visual representation for the number of r...Get price
