Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, insulating gas, 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 insulating gas can do in centimeters.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

5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substationengineering uses the gas sulfur hexafluoride for insulation, whereas AIS uses air insulation in a metal-clad system. Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). GIS systems use fixed, mounted circuit breakers. The sealed mounted breakers are a ‘sealed-for-life’ technology, whereas the AIS breaker can be removed for maintenance and troubleshooting.Get price
