US Patent:

41829840, Jan 8, 1980

Filed:

May 5, 1978

Appl. No.:

5/903324

Inventors:

John A. MacFadden - Raleigh NC
James E. Ramsey - Raleigh NC

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G01R 114
G01R 1110

US Classification:

324152

Abstract:

A watthour meter damping assembly includes a U-shaped magnetic yoke and a pair of highly coercive and anisotropic permanent magnets projecting in facing relationship from the ends of the yoke. Opposing pole faces of the magnets form an air gap receiving a meter disc to be magnetically retarded. A single temperature compensator extends over the pole faces of the permanent magnets to form a compensating shunt flux path around the air gap. The compensator and magnetic yoke extend substantially parallel to each other from the inner and outer pole faces, respectively, of the magnet pair.

James E. Ramsey - Raleigh NC
Auburn K. Griffin - Sanford NC

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G01R 1102

US Classification:

324137

Abstract:

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.

International Classification:

G01R 1102

US Classification:

324137

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.
