Gas-Insulated Substations - GIS

Nov 10, 2010 · 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.Get price

A Spatial Analysis of MoscowFuel Stations - GIS Lounge

Mapping Fuel Stations in MoscowUnderstanding The Impact of Fuel Stations in MoscowSpatial Location of Fuel Stations in MoscowEconomics of Fuel StationsEnvironmental Impacts of Fuel StationsThe Road/Traffic Safety AspectsAs input data the OpenStreetMap(OSM) and the Moscow Government OpenData were used. The OSM data contains not only geotargeted points but also has attributive data like the brand-name of the fuel-stations. It took a lot of manual work to add dozens of fuel stations and to verify their location (on foot, by car, through Yandex (the Russian search engine), Google StreetView, and with high resolution satellite images, etc). While I am not sure that the final map contains all fuel stations, the majority of them have been located and mapped. You can viewed the results of this project on the web GIS GeoMixer site. This web map is hosted by the Moscow State University Business School server: http://geo.mgubs.ru:8080/api/index.html?permalink=KA1Y4&A96WP.
