The invention relates to a sensor(S), in particular for an electrical network of an electrically driven vehicle, in particular in an electric car. The sensor according to the invention comprises first of all a measuring device (ME) for current measurement and/or for voltage measurement in the electrical network, in particular with a low-resistance current sense resistor for current measurement according to the four-wire technique. Furthermore, the sensor(S) according to the invention comprises an integrated insulation monitoring device (ME, IQ, Rk, S) for monitoring an electrical insulation of high-side and/or low-side of the electrical network. The sensor(S) according to the invention is characterized by the fact that the insulation monitoring device (ME, IQ, Rk, S) operates actively and impresses measurement pulses into the electrical network for insulation monitoring.

Sensor for a vehicle electrical system

The invention relates to a current measuring resistor () for measuring an electrical current, in particular in the kA range, in a high-voltage network. The current measuring resistor () according to the invention comprises two connection parts () for conducting the electrical current in and out and a resistance element () made of a low-impedance resistive material. The resistance element () is arranged between the two connection parts () in the direction of current flow and is joined to the two connection parts (), such that the electrical current to be measured flows through the resistance element () during operation and produces a voltage drop across the resistance element (). According to the invention, the connection parts () and the resistance element () each have a substantially round cross section, in particular a substantially circular cross section, in a section plane perpendicular to the direction of current flow of the electrical current.

Current measuring resistor and associated production method

The invention relates to a coupling for electrically and mechanically connecting medium-voltage or high-voltage components, in particular for voltages of 1 kV to 52 kV, comprising a first connecting piece for mechanically and electrically connecting a medium-voltage or high-voltage component, in particular for connecting to a complementary connecting piece of a bushing of a switchgear cabinet, and a second connecting piece for mechanically and electrically connecting another medium-voltage or high-voltage component, in particular for connecting to a complementary connecting piece of an electrical cable, wherein the two connecting pieces of the coupling belong to complementary connection types, which fit together mechanically, and comprising a low-resistance current sensing resistor, which is built into the coupling and electrically connected between the first connecting piece and the second connecting piece in order to measure a current flow between the first connecting piece and the second connecting piece.
