摘要： Apparatus for contactless testing a closed loop electrical connection in partcular suited for testing the interconnection of photovoltaic cells in a solar pane. The apparatus comprises tow coils. The first coil is a driving coil (11) comprising at least one first winding (15) for generating a varying magnetic field in the area (14) enclosed by the closed loop electrical connection. The second coil is a detection coil (12) comprising at least one second winding (16) for generating a voltage when being subjected to the magnetic field generated by the current in the closed loop electrical connection. The apparatus further comprises a compensation loop (13) for compensating the direct mutual induction of the first coil and the second coil. The compensation loop allows the use of uncomplicated electronics for testing the interconnection, which electronics can easily be implemented in a hand held device.

摘要： A sensor circuit is configured and operated in the presence of interference. In connection with various example embodiments, a stray magnetic field is sensed with current sensors that also respectively sense current-induced magnetic fields generated by current flowing in opposing directions through different portions of a conductor. The current-induced magnetic fields and the stray magnetic field are coplanar, and the current sensors are arranged such that a portion of the output from each current sensor corresponding to the stray magnetic field is canceled when the sensor outputs are combined.

摘要： The invention derives a more effective way of description from the traditional definition on the probe spatial resolution, and put forward a spatial resolution calibration method based on the controllable probe with axial-distribution EMF above the planar transmission lines, including to give derivative definition on the probe spatial resolution through normalization, to set up controllable probe calibration platform with axial distribution of EMF above the planar transmission line; suitable for spatial resolution calibration with travelling wave in case of high frequency and standing wave in case of low frequency, which can effectively control and reduce the errors generated by the probe size as well as sensitivity, high frequency and low frequency of signal detection equipment.
