This abstract first appeared for US patent application 18904140 titled 'DEVICES AND METHODS FOR DETERMINING AN ELECTRICAL OVERCURRENT EVENT
Original Abstract Submitted
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.
