Detecting SF6 decomposition sensor

Apr 12, 2005The sf6 gas decomposition products detector (SF6DPD) is a portable hand held instrument intended for use by field personnel for the detection and location of sf6 decomposition products in sf6 gas filled electrical equipment, and in air. When electrical fault conditions occur, the location of the problem is not always evident.
