Abstract
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.
