Asset Inventory and Infrastructure InsightsOptimizing Field OperationsCollaborating and Sharing Geospatial DataCreating Field Data Collection ProjectsCollecting Field DataEditing Data and Overseeing FieldworkSharing Data with Clients, Subcontractors and ManagersIt’s crucial to have an accurate asset inventory with electric poles, transformers, cable lines, substations and other electric utility assets properly mapped. GIS allows you to manage the asset data a lot easier and enables you to take insight from the infrastructure. With a properly set up GIS suite, you can get amazing insights from infrastructure data by: 1. Analyzing usage patterns 2. Recognizing problems and risks like power outages 3. Having oversight about energy consumption 4. Finding potential threats to the power grid 5. Managing utility asset repairs Before you start with the analysis, it’s essential to have quality data; you need to know the condition of assets, their locations and other info. Which brings us to the next point.Get price

Gas-Insulated Substations - GIS - Electrical Engineering Portal

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 insulating 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

GIS vs AIS - Substation Earthing - Electrical Engineering Portal

Reduced Ground AreaInduced CurrentsFast Transients Overvoltages and TGPRSummaryNormally, with an AIS, a single uninsulated copper loop laid around the perimeter of the site with cross connections to pick up the individual items of equipment, will provide a sufficiently low resistance electrode. However, the smaller area occupied by a CIS means that the size of the main earth loop will be smaller and therefore the total amount of conducting path will also be smaller. The possible solutions to reduce the earth electrode resistance are (1): 1. High density grid: frequent and short connections from the switchgear elements to the earth grid. This reduces the TGPR in the GIS and contributes to reduce the total earth electrode resistance, but not in direct proportion to the additional length. 2. Connection to the reinforced concrete mat:connecting the reinforcing steel mesh and structural steel to the earth grid will reduce the total earth electrode resistance. However this is complicated and it has to be done in a way that avoids problems of overheating and damage o...Get price
