Advantages of comprehensive monitoring for critical circuit

Older insulating gas density switches do not detect Sulfr hexafluoride leaks early or problems in the cables. Analog sf6 gas density transmitters are subject to spurious alarms due to EMC and are not precise enough. Comprehensive breaker monitoring systems must use very precise digital insulating gas temperature and pressure sensors capable of detecting very small leaks of Sulfr hexafluoride.
