    May 31, 2011 · SF6 Gas Leak Detector (Dilo) - Substation Maintenance. SF6 gas is one of the common insulating medium of high voltage power circuit breakers. Eventhough this gas is odorless, colorless, and non-toxic, it is one of the greenhouse gases that contribute to the destruction of ozone layer. Therefore, proper handling of this gas must be done inorder to minimize, or eliminate the escape of this gas to the atmosphere.
