【 摘 要 】

Measurements at ORNL were made on the Kahn moisture sensor which Doble Engineering wants to evaluate for use in SF6 circuit breakers. Tests conducted at ORNL indicate that vacuum conditions, as might be found in SF6 circuit breakers prior to filling with SF6, could lead to significant changes in calibration, resulting in erroneous readings of moisture content. Similar effects might also be observed in cases where SF6 byproducts are present, due the reactivity of some of these byproducts with water.
