Abstract
Abstract The present invention relates to a current divider for a measuring transducer. The current divider includes two conductors. The first conductor, which is operable as a shunt, comprises two generally flat legs which extend parallel to one another. Each leg defines one aperture into which the core of the measuring transducer extends. The second conductor is z-shaped having two arms and a bridge extending between the two arms. The arms are electrically connected to one of the legs and the bridge crosses the aperture therein, so that the bridge is surrounded by the core.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
A current divider, for use in a measuring transducer for the potential-free measurement of currents, comprising in combination, a current conductor adapted to receive a current to be measured, said current conductor including a first conductor operable as a shunt and including a flat conduit comprising two generally flat legs, positioned so that they face one another, each leg defining one aperture, a core of said measuring transducer extending into said apertures, at least one second conductor having Z-shape, and including two arms adjacent one of said legs and a connecting bridge, said Z-shaped conductor being connected to a surface of said one leg, said one leg being electrically connected to the ends of said arms, and said bridge crossing the aperture of said one leg and being surrounded by said core.
Claim 2
Dependent Claim
132 words
A current divider, for use in a measuring transducer for the potential-free measurement of currents, comprising in combination, a current conductor adapted to receive a current to be measured, said current conductor including a first conductor operable as a shunt and including a flat conduit comprising two generally flat legs, positioned so that they face one another, each leg defining one aperture, a core of said measuring transducer extending into said apertures, at least one second conductor having Z-shape, and including two arms adjacent one of said legs and a connecting bridge, said Z-shaped conductor being connected to a surface of said one leg, said one leg being electrically connected to the ends of said arms, and said bridge crossing the aperture of said one leg and being surrounded by said core.
