  • Study on field demonstration of high‐sensitivity SF6

    The authors proposed an algorithm to accurately estimate the average gas temperature from the tank surface temperature for establishing a high‐sensitive SF6 slow leak detection technology. Since the gas temperature depends on the temperature of the conductor, the algorithm was characterized by estimating the gas temperature from the tank surface temperature and the load current.Author: Masaru Tatemi, Hisao Inami, Toshiaki Rokunohe, Makoto Hirose

  • PGE Phases Out SF6 Greenhouse Gas | TD World

    Feb 21, 2019Fixing a single SF 6 leak has an average cost of US$25,000. Ten percent of the installed dead tank circuit breakers (DTCBs) were leaking SF 6 in excess of the manufacturer certified leak rate and the probability of leakage was increasing with the aging of the DTCBs. Operating costs were forecasted to increase as a result of future increased SF 6 leaks.
