Device and method for measuring a current flowing in an electrical conductor |
摘要 |
A device for measuring a current flowing in an electrical conductor. The device comprises a magnetic circuit coupled to an electrical conductor. The magnetic circuit has an air gap and a magnetic field sensitive component disposed in the air gap to measure a magnetic field generated by the electrical conductor. A control core has a control winding configured to control an effective length of the air gap when the control winding is energized. A magnetic shield at least partially encloses the magnetic circuit, the magnetic field sensitive component and the control core.
