  • Advantages of comprehensive monitoring for critical

    Older SF6 density switches do not detect SF6 leaks early or problems in the cables. Analog SF6 density transmitters are subject to spurious alarms due to EMC and are not precise enough. Comprehensive breaker monitoring systems must use very precise digital SF6 temperature and pressure sensors capable of detecting very small leaks of SF6.
