ABSTRACT:
A Rogowski sensor is provided for measuring a current of an electrical conductor. The sensor has a Rogowski coil, which has an electrical winding resistor, and an integration device which is connected to the Rogowski coil and is intended to generate an output signal which is proportional to the electrical current to be measured by the Rogowski sensor. The integration device is formed by the winding resistor of the Rogowski coil and a capacitance which is connected to the two winding connections of the Rogowski coil, and for the output signal from the integration device to be formed by the voltage applied to the capacitance.
