Dependence of Mutual Inductance of a Precise Rogowski Coil on the Primary Conductor Position

A Rogowski coil is well-known current-to-voltage transducer, and in order to use it for the high-accuracy measurement of AC current (at power supply frequency) all influencing quantities and their contribution should be recognized and analyzed. Therefore, in this paper the analysis of the partial influence due to the position of the primary conductor relatively to the secondary coil, with the nonhomogeneous density of secondary turns, is analyzed. The measured deviation of the mutual inductance in this case showed very good agreement with the theoretical prediction, which is promising toward the expected application of such sensor.
