Smarter Inspections with ArcGIS - GIS Mapping Software

With GIS, you have the power to determine which of the thousands of your utility’s manholes need to be inspected and cleaned. You can cluster these manholes spatially on a map in your utility’s GIS. As a result, you can schedule inspections for minimal crew travel time, or you can combine inspections with other fieldwork that is happeningGet price

On-Site SF Gas Analysis - MBW Calibration AG

By Daniel Mutter, MBW Calibration AG A Brief History The use of SF 6 gas insulated switchgear ~GIS expanded rapidly during the 97s thanks to its reliability, compact dimensions, durability and safety.

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 (Sulfr hexafluoride) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS. The characteristics of the insulating gas gas also allow the extinction of arcs which can occur during disconnection of live contacts.Get price
