Abstract: This disclosure concerns a sensor device including an electric conductor including a flat elongated shape. The electric conductor includes at least one cutout portion extending along the width of the electric conductor (200), the cutout portion extending from a first longitudinal side of the electric conductor towards an opposite second longitudinal side of the electric conductor, wherein a residual portion of the electric conductor remains between the cutout portion and the second longitudinal side of the electric conductor. A magnetic sensor is provided for measuring a magnetic field emanating from the electric current flowing through the electric conductor, wherein the magnetic sensor is arranged next to the electric conductor opposite the cutout portion.

Abstract: A device for detecting an electrical overcurrent event includes a current sensor configured to generate a first sense signal representative of an absolute current value of an electrical current through an electrical conductor. The device further includes a sense unit configured to generate a second sense signal representative of a temporal change of the electrical current. The device further includes an adjustment unit configured to adjust a previously set first threshold value for the absolute current value based on the second sense signal. The device further includes a detection unit configured to detect an overcurrent event in the electrical conductor based on a comparison between the first sense signal and the adjusted first threshold value.

Abstract: A system may include a busbar to conduct a current. The busbar may include a sensing structure. The system may include a magnetic sensor to sense a magnetic field produced by the current in the busbar. The magnetic sensor may be arranged near the sensing structure. The system may include a thermal element in or near the sensing structure. The thermal element may facilitate dissipation of heat through the sensing structure of the busbar.
