Gas-insulated Switchgear (GIS) Testing - OMICRON

Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (sf6 gas) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS. The characteristics of the gaz sf6 gas also allow the extinction of arcs which can occur during disconnection of live contacts.Get price

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
