Abstract
289,426. Landis et Gyr Soc., Anon. April 27, 1927, [Convention date]. Induction motor meters. -One of the limbs of the current core 2, which are connected by a magnetic shunt 4, is provided with a ring 5 of electrically conducting material to compensate for the drop in the curve of error caused bv the magnetic shunt with an inductance load. Separate voltage and current cores are arranged respectively above and below the disc. The ring 5 is of copper, aluminium, brass or alloys. The shunt 4 is secured to the core by iron screws and non-magnetic metal is interposed between the shunt 4 and the core 2.
