WHITEPAPER: On-line SF6 monitoring – Breaking Paradigms

This paper endorses the monitoring of SF6 gas to help identify leakages and possible changes in moisture content at an early stage, then track and compare over time. An end-user software solution is proposed that tracks SF6 leakage rate/amount of loss in real time, possesses an artificial intelligence based on international standards and experience shared from High Voltage field service experts, and provides valuable condition base information to fulfill SF6 management tools to establish controls through on-line monitoring. Currently, SF6 on-line density monitoring is used primarily as back-up protection for current temperature compensated pressure gauges “standard for electrical equipment”.
