The Effect of Electromagnetic Interference Shielding Effectiveness on Rogowski Coils

摘要

The aim of this work is to evaluate the electromagnetic interference on Rogowski coils, as well as to observe consequences when they are shielded with different materials using as a test environment a Crawford cell. A Rogowski coil in a Crawford cell is modeled by a magnetodynamic vector potential formulation. The model takes into account the effect of the displacement current on the electromotive force induced in the coil and measured for different frequencies.
