Modular Switchgear Monitoring (MSM)
Condition monitoring for high-voltage switchgear
Modular Switchgear Monitoring (MSM) is used to supervise, manage and analyze performance of all type of high-voltage switchgear in new installations as well as a retrofit solution in existing high-voltage assets. The system operates independently of existing control and protection devices and can be installed in new substations or retrofitted in existing installations. By continuously monitoring critical parameters, MSM provides the base layer for a predictive maintenance strategy for the installation.The system is compliant with IEC 61850 and DNP 3.0 and it is provided with a web interface where all monitored data are accessible.
Applications
Based on the monitoring application, MSM is offered in 2 versions with additional options:
- MSM-I is designed for SF6 and gas monitoring allowing early detection and prevention of critical gas leakages in high-voltage switchgear, enabling to reduce gas emissions
- MSM-II enables circuit-breaker monitoring in addition to gas monitoring, for improved operational reliability and performance of the circuit-breakers
- MSM is now available with options that enable humidity monitoring, internal arc localization, heater monitoring, disconnector and earthing switch monitoring
- MSM is designed to be compatible with the new EconiQTM solutions
Why Hitachi Energy?
- Improved reliability with reduction in unplanned downtime
- Optimized predictive and proactive maintenance by early warnings
- Provides adequate time for maintenance planning with low chances of failure
- Greater diagnostic capability in case of failure through the recorded data, reducing time to repair
- Improved environmental/ regulatory compliance with reduced SF6 leakages
- Software independent visualization
