| 摘要 |
The invention relates to a device for measuring the intensity (1) of a strong current passing through a wire (1), said device comprising a magnetic sensor (2) in the form of a loop surrounding the wire (1), and an arc runner (3) which consists of a conductive material that surrounds the wire (1) and conducts a high frequency counter-current, the intensity of which is adjusted in order to cancel the magnetic field (H). The inventive device is characterised in that the arc runner (3) consisting of a conductive material is part of a short circuit and surrounds the magnetic sensor (2).
