摘要：
A new circuit for current measurement is described which incorporates a microwave filter tuned by an yttrium-iron garnet placed close to the high-voltage transmission line conductor as a magnetic field strength sensing element. The resonance frequency of this filter is linear dependent upon the magnetic field generated by the current flowing in a high-voltage line conductor. The second ground electrode is represented by a circuit that is tracking the resonance frequency of this filter. A schematic diagram and the results of tests are included.
