ABSTRACT:
An assembly group for current measurement comprises a conductor plate with three cuts and a measuring element placed on the conductor plate that has a difference sensor formed from two magnetic field sensors. By means of the three cuts a first and a second conductor section are formed in the conductor plate, wherein the current direction in the second conductor section runs opposite to the current direction in the first conductor section. The first magnetic field sensor is located above the first conductor section and the second magnetic field sensor is located above the second conductor section. The magnetic field sensors are sensitive to a magnetic field that runs parallel to the surface of the conductor plate and orthogonal to the current direction in the two conductor sections.
