SF6 Monitoring System

SF6 is an inert gas mixture with excellent dielectric properties, and it has been widely applied on very high voltage parts such as Gas-Insulated Switchgears (GIS) in order to reduce its size or increase the working voltage. SF6 also has a high contribution for the Greenhouse Effect so its use is deeply regulated. As well as being damaging to the environment, SF6 is heavier than air and inside GIS rooms may cause asphyxia when leaks occur.

Eneida’s SF6 Monitoring System allows an automatic local and remote warning if any leakage happens as well as automatic activation of the Ventilation. Several sensor’s are located close to the GIS. Local warnings by traffic lights and buzzers are fixed in the entries doors and ventilators are strategically located to guarantee quickly air renovation, when needed. Warnings are automatically transmitted to the PLC, Scada and to remote users.

Increase of Safety to the local operators due to an automatic detection, luminous and sonorous warnings;
Increase of Safety for any technician or operator accessing the room, due to local warning through traffic lights installed in the entries;
Blocked access to the substation is prevented;

Decrease of accidents as the leakage detection is made right in the beginning;
Decrease of insurance costs due to increasing safety in a dangerous area;
Reduction of environmental impact as Sf6 gas leakages are detected early and automatic.
