Auxiliary winding for driving electric meter accessories

Abstract

A flux shunt includes a pickup plate parallel to, and closely spaced from, an outer surface of a voltage stator winding of a voltage stator for an electric meter drive apparatus. A flux-return tab of the flux shunt passes through an auxiliary coil and enters a flux-return slot in the voltage stator core of the voltage stator. The flux-return tab is biased into intimate mechanical contact with a surface of the flux-return slot both to prevent buzzing and to provide a low-reluctance return path for flux picked up by the pickup plate. The return flux, passing through the auxiliary coil induces a voltage in windings thereof for powering meter accessories such as, for example, a light-emitting diode whose illunination is indiciative of excitation of the core material of the voltage stator.
