  • An Introduction to Gas Insulated Electrical Substations

    2020-10-6A gas insulated substation (GIS) is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as SF6, or sulfur hexafluoride gas as the insulating medium. In comparison, a conventional (AIS) or Air-Insulated Substation, uses atmospheric air

  • Leak Detection in Liquid Bulk Storage Tanks

    2019-12-2Leak Detection as service vs. Permanent Leak Detection Solution Some mass-based leak detection systems were developed as a service method, which means a crew of technicians would go to a tank site, install the equipment and monitor for a pre-determined time, usually 48 hours or more, to determine if there is an existing leak.
