A method of operating one high-voltage network in a motor vehicle

It is a method for operating a high-voltage network (10), in particular in a motor vehicle, are shown, which are in incipient shorts already detected early and securely. Therefore, the invention relates to a method for operating a high-voltage network (10) in a motor vehicle having a plurality of electrical components (12, 13, 14, 16, 18), by - detecting a respective electrical current into and out of each of the electrical components (12, 13, 14, 16, 18), - forming a sum current (30) through proper sign summing the detected electric current levels, marked by, - determining a dynamic first threshold (32) and a dynamic second threshold (34) for a sum of the total currents (y - generating a first predetermined signal if the sum of the total currents (y - generating a second predetermined signal when the sum of the total currents (y
