iSGM Online Intelligent SF6 gas Monitoring Software

Utilize on-line automation to reduce the costs associated with SF6 gas management

Real-time monitoring of SF6 gas leakage on-line with any or all of the following assets: Gas Insulated Substation or Gas Insulated Switchgear (GIS), Gas Insulated Transformer (GIT), Gas Insulated Lines (GIL) and Gas operated Circuit Breakers (GCB).

Switchgear And Breaker
Works with These Assets


  • Real time automated alerts for time to refill / time to lock out / fast changing events and ranking tables at utility level / substation level
  • Real time automatic ranking of highest leaking gas zones at global utility level and / or per substation level
  • Real time automation of year to date and per annum SF6 emissions and leak rates
  • Customizable report generator to allow emissions reports to be created automatically for third party environmental agencies at touch of a button
  • A fully flexible, modular and scalable system to monitor anything from one gas insulated circuit breaker with three gas zones to largest GIS in world with thousands of gas zones
  • IEC 61850
  • Web based or Client-server software; SMS or email alerts
  • SmartSUB CBM software can integrate Qualitrols SF6 gas density, partial discharge and circuit breakers monitors into one platform


  • Any SF6 gas density monitor having 4-20 mA or MODBUS output
  • Cabinet with HMI and UPS
  • Weather proof enclosures for Network Nodes (if no space available in breaker cabinets)
  • SCADA / PI integration
  • Environmental agency system integration
