Device for measuring an electric current that flows through a strip conductor
The invention relates to a device for measuring an electric current ( 1 ) that flows through a strip conductor ( 1 ). The inventive device comprises a measuring conductor ( 3 ) which extends along the current flow direction and in the proximity of a measuring section ( 2 ) of the strip conductor ( 1...

| Zusammenfassung: | The invention relates to a device for measuring an electric current (
1
) that flows through a strip conductor (
1
). The inventive device comprises a measuring conductor (
3
) which extends along the current flow direction and in the proximity of a measuring section (
2
) of the strip conductor (
1
). The one end of said measuring conductor is directly and electrically connected to the one end of the measuring section (
2
). The remaining end of said measuring conductor is provided with a first measured value tap (
4
). The device comprises a second measured value tap (
5
) which is electrical connected to the remaining end of the measuring section (
2
). The aim of the invention is to freely select the dimensions of the strip conductor (
1
) and the measuring conductor (
3
) and especially to use a conventional strip conductor (
1
) and to better use said device and have a greater measuring accuracy at the same time. According to the invention, the measuring section (
2
) is rectilinear. The second measured value tap (
5
) is directly connected to the measuring section (
2
). The measuring conductor (
3
) is essentially currentless and a voltage (U) is picked up on the measured value taps (
4, 5
) as a measure for the current (I) to be measured. |
