Gas-Insulated Substations - GIS

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

An Introduction to Gas Insulated Electrical Substations - PDH

A GIS is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as sulfur hexafluoride gas (sf 6) as the insulating medium. In comparison, a conventional (AIS) or Air-Insulated Substation, uses atmospheric air as the dielectric gas medium, as these types of substations are almost always located at outdoor locations.Get price

The Role of GIS and SCADA in Energy | GIS Integration With

Monitoring Status Information, Along with Geographically Correct LocationsIntegrating The Advantages of Zenon Energy EditionAccessing Maps Both Online and OfflineMore Efficient ProcessesThe term dynamic data refers to data that is continually updated as conditions change, while static data stays the same once it is recorded. Dynamic data allows you to monitor conditions in real time and see trends over time, while static data forms a foundation and reference point. Combining GIS and SCADA enables you to visualize dynamic data related to current conditions with static geoinformation. For instance, you can see which electrical lines are under voltage in which locations. This gives you an accurate, real-time view of your system that is easier to comprehend than if the data were listed in a table. You can also more easily spot patterns related to location in your data. You can also easily select the data layers you want to see, which allows you to apply your data to solve a wide range of challenges. Because SCADA and GIS enable you to monitor the status of your network in real time, it can help to catch and correct problems more quickly.Get price
