Device for measuring electric current, including a sensor sensitive to magnetic flux and intended in particular for electrically propelled vehicles |
摘要 |
A device is provided for measuring electric current having at least one probe sensitive to magnetic flux arranged in the air gap of an annular core through which at least one conductor of a current to be measured is intended to pass. A compensation winding is wound of the core and a measuring resistor is connected in series with the compensation winding. A circuit is provided for regulating the supply current to the compensation winding regardless of the direction of the current to be measured. The circuit is controlled by the output signal of the sensor which is sensitive to magnetic flux.
