Monitoring of SF6 Breakers leak testing

Feb 19, 2008This feature provides a clear, visual indication of the gas density relative to the breaker fill pressure and set points. The 2TC is economically ideal when monitoring individual SF6 tanks. Installing the 2TC on individual phases reduces the need for numerous plumbing connections and the potential for costly leak points.
