SENSOR SET FOR VEHICLE ELECTRICAL SYSTEMS

Abstract

The invention proposes a sensor (S), specifically for the electrical network of an electrically driven vehicle, specifically an electric motor. The sensor (S) of the invention comprises first of all measuring elements (ME) for measuring current and / or voltage in the electrical network, specifically by means of a low-resistance current sensing resistor for measuring current using four-wire techniques. Furthermore, the sensor (S) of the invention comprises an integrated insulation monitoring element (ME, IQ, Rk, S3) for monitoring the insulation of the high-voltage and / or low-voltage side of the electrical network. The sensor (S) of the invention differs in that the insulation monitoring element (ME, IQ, Rk, S3) operates in an active manner and inputs measurement pulses into the electrical network for insulation monitoring.
