Abstract
Abstract A current divider for use in connection with a measurement transducer. The measurement transducer includes a magnetic core, is formed as a substantially flat and longitudinal conductor with two longitudinal slits so as to partition the flat conductor into at least a measurement conductor, and at least two shunts are connected in parallel with the measurement conductor. The shunts define a plane, and the measurement conductor is disposed in the plane between the shunts. The flat conductor has two openings along the longitudinal direction, to receive the magnetic core. One slit communicates with one opening, and the other slit communicates with the other opening.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A current divider, for use in connection with a measurement transducer, and wherein the measurement transducer includes a magnetic core, comprising in combination a substantially flat and longitudinal current conductor having at least two longitudinal slits, thereby partitioning the flat conductor into at least a measurement conductor and at least two shunts connected in parallel with the measurement conductor, said shunts defining a plane, said measurement conductor being disposed in said plane and between said shunts, said flat conductor having two openings along the longitudinal direction, said openings being adapted to receive said magnetic core, one slit communicating with one opening, the other slit communicating with the other opening.
Claim 2
Dependent Claim
109 words
A current divider, for use in connection with a measurement transducer, and wherein the measurement transducer includes a magnetic core, comprising in combination a substantially flat and longitudinal current conductor having at least two longitudinal slits, thereby partitioning the flat conductor into at least a measurement conductor and at least two shunts connected in parallel with the measurement conductor, said shunts defining a plane, said measurement conductor being disposed in said plane and between said shunts, said flat conductor having two openings along the longitudinal direction, said openings being adapted to receive said magnetic core, one slit communicating with one opening, the other slit communicating with the other opening.
Claim 3
Dependent Claim
46 words
The current divider as claimed in claim 1, wherein the current conductor is U-shaped so as to form two legs, and one opening is superimposed onto the other opening, said legs being electrically insulated from one another, and being in intimate thermal contact with one another.
Claim 4
Dependent Claim
34 words
The current divider as claimed in claim 1, wherein said flat conductor has a predetermined width, and wherein the width of said slits is small compared to said predetermined width of said flat conductor.
Claim 5
Dependent Claim
32 words
The current divider as claimed in claim 2, wherein said legs are spaced from one another by a predetermined distance, the width of said slits being small compared to said predetermined distance.
Claim 6
Dependent Claim
27 words
The current divider as claimed in claim 1, wherein each opening has a prearranged width, the length of said measurement conductor being large compared said prearranged width.
Claim 7
Dependent Claim
52 words
The current divider as claimed in claim 2, wherein said flat conductor has two additional longitudinal slits, said slits thereby partitioning said flat conductor into two outer shunts and a center shunt, as well as into two measurement conductors, each measurement conductor being disposed between one outer shunt and said center shunt.
Claim 8
Dependent Claim
20 words
The current divider as claimed in claim 1, further comprising means for maintaining the current density in said shunts constant.
Claim 9
Dependent Claim
27 words
The current divider as claimed in claim 7, wherein said means for maintaining the current density in said shunts constant comprises recesses formed in said flat conductor.
Claim 10
Dependent Claim
50 words
The current divider as claimed in claim 7, wherein said means for maintaining the current density in said shunts constant comprises shaping said flat conductor so that it has a width varying to such an extent along its length so as to maintain the current density in said shunts constant.
Claim 11
Dependent Claim
48 words
The current divider as claimed in claim 6, wherein some portions of the shunts are associated with one leg, and the remaining portions of the shunts are associated with the other leg, said some portions of said shunts being substantially super-imposed with the remaining portions of said shunts.
