Research on Performance of Different Hall-Effect Switch on Smart Meter

Abstract With the deepening application of smart meter and improvement of electricity information acquisition system, more and more problem recorded by smart meter being discovered in scene, such as constant magnetic field events, communication failure event. Some smart meter recorded tends of thousands constant magnetic field events and the reason is varied, however, the ultimate cause of the event is the hall-effect switch on smart meter. This paper just analyzed the event of constant magnetic that detected frequently by the electricity information acquisition system, and the result showed that the hall-effect switch from different manufacturers has different performance.
