Abstract： Hall sensor is the specific switchposition sensor of bypass-switch in UHV system, and it is important to the process of deblock the single valve group while the anothervalve group is operating in the same pole. In this paper a valve group deblock failure caused by the Hall sensor fault is analized, and the improvement suggestions are proposed to regularly test on Hall sensor.
