【 摘 要 】

Measurements at ORNL were made on the Kahn moisture sensor which Doble Engineering wants to evaluate for use in SF{sub 6} circuit breakers. Test conducted at ORNL indicate that vacuum conditions, as might be found in SF{sub 6} circuit breakers prior to filling with SF{sub 6}, could lead to significant changes in calibration, resulting in erroneous readings of moisture content. Similar effects might also be observed in cases where SF{sub 6} byproducts are present, due the reactivity of some of these byproducts with water.
