Magnetic shielding of Rogowski coils

This paper describes the impact of Rogowski coil (RC) construction imperfections on measurement errors. A procedure is shown for detecting RC non-homogeneity using a rotary dipole magnetic field inducing a current inside an RC. The influence of RC magnetic shielding on reducing spurious fields is described.
