摘要： The present invention is for an induction meter having a voltage and a current magnetic section. The voltage magnetic section is comprised of a substantially E-shaped laminated magnetic core having a center leg terminating at a main pole face and two adjacent legs terminating at coplanar auxiliary pole faces on opposite sides of the main pole face, and includes a spacer bracket located between a first side of the voltage magnetic core and a first voltage shunting member. The spacer bracket carries a self-aligned, light load adjustment assembly having a movable tab extending over portions of one of the auxiliary pole faces and the main pole face thereby providing an adjustable magnetic flux shunt path. A second voltage shunting member is located in magnetic proximity to the first side of the core and spaced from the first voltage shunting member by a nonmagnetic spacer. The second voltage shunting member has a fixed tab in magnetic proximity to the other auxiliary pole face and a fixed tab in magnetic proximity to the movable tab. In this manner, the first voltage shunting member, the second voltage shunting member and the movable tab all provide magnetic flux shunt paths.

摘要： An induction meter has an improved voltage magnetic section comprised of a substantially E-shaped laminated magnetic core having a center leg and two adjacent legs. A nonmagnetic multi-function support and spacer bracket extending from one of the adjacent legs to the other adjacent leg has three perpendicular extensions which give the bracket a substantially E-shaped configuration and which each are riveted to one of the legs of the magnetic core. The perpendicular extension riveted to the center leg provides support for the voltage coil. A light load adjuster bracket provides an adjustable shunt path for magnetic flux between the main pole face and the auxiliary pole faces. The light load adjuster bracket is located in magnetic proximity to the first side of the magnetic core and is separated therefrom by the nonmagnetic bracket.
