| 摘要 |
<p>The present invention is a current sensor architecture using a planar coils in close proximity to a current conductor to detect the rate of change of current in the conductor (and hence, by using an integrator, to recover the AC current). The current sensor is optimised to reject uniform external magnetic fields, gradient external magnetic fields, and fields from one or more conductor assemblies in fixed locations in close proximity to the current sensor, such as might be found in a polyphase electric meter with multiple current sensors.</p> |
