Modular Switchgear Monitoring -gas Monitoring for Gas

The Modular Switchgear Monitoring (MSM) is an add-on system to supervise SF 6-gas density. The system is suitable for all kinds of switchgear layouts and operates independently of existing control and protection devices. MSM is applicable for new sub-stations and for retrofit of existing installations. Availability – OptimizationGet price

Swissgrid is responsible for all of this

The switchgear systems housed in the substations are nodes between lines. Here, the energy is transformed to a lower voltage level and passed on to the lower grid levels. Swissgrid’s grid control rooms also isolate and connect lines in the switching substations by means of switching operations, in order to guide the energy flows.Get price
