Abstract
239,546. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). Sept. 8, 1924, [Convention date]. Drawings to Specification. Induction motor meters with several motor fields are compensated for the errors resulting from the mutual action of the motor fields with different phase sequences by arranging an adjustable plate of conducting material such as copper, brass, or aluminium, or of ferro-magnetic material such as iron, in the path of the stray flux of a. voltage core.
