摘要： An on-load tap changer position sensor includes a series of radially spaced reed switches and a magnetic indicator that is rotated by a shaft that is coupled directly or indirectly to a load tap changer. As the position of the magnetic indicator changes, the location of the magnetic field created by the magnetic indicator moves. Each reed switch includes a set of contacts that close when in the presence of the magnetic field. The closed contacts create a voltage differential that is detected and used to determine the location of the closed reed switch and thus the position of the on-load tap changer.
