Modular Switchgear Monitoring (MSM)

The Modular Switchgear Monitoring (MSM) is an add-on system to supervise SF6 density in enclosures of high-voltage gas-insulated switchyards. It operates independently of existing control and protection devices. MSM is applicable for retrofit of existing substations and for new installations.


  • SF6 density monitoring in Gas Insulated Switchgear
  • Optimize maintenance by using trend calculation
  • Provides data for remote condition monitoring and advanced maintenance strategies

Why ABB?

  • Software independent visualization
    • The integrated web server allows displaying the monitoring information on a web-browser-based user interface in the LAN or WAN
    • Web client shows temperature-compensated pressure, leakage rates, alarms and displays a graphical trend chart of the SF6 pressure
    • Ranking of the analyzed data supports the customer's maintenance planning of the switchgear.
    • User management prevents unauthorized access to the system and its data
  • Local HMI
    • Local displays can be installed in the bay cubicle.
    • Green and red LEDs signalize device status and gas value alarms
    • Easy navigation through the measurement data, alarm list and event history
  • Network Control Center
    • Transfer of data to Network Control Center via IEC 61850 or DNP3 for further processing
    • Critical alarm can be sent via conventional alarm contact
