PSEG Field Experience and Research findings in gaz sf6 leak

PSEG has been active in leak detection from the early years of the first camera technologies – and has continued to research and evaluate emerging techniques. Recently PSEG had the opportunity to simultaneously have both an active and a passive leak detection technology in a number of outdoor PSEG substations. Leak Sealing - Introduction

6 in them according to the type of circuit breaker [3]. SF 6 is introduced via a permanent valve (like STS type – Siemens uses a clenched tube). The equipment are "Helium Tight" tested, and, in case of leak, the leakage point is detected with SF 6. Then the apparatus is filled with SF 6. The counter, placed next to the gas valve gives the mass (weight at sea level)
