In this paper, we investigate the performances of Rogowski coils with superparamagnetic core. Rectangular cross-section cores are built by a 3D printer and filled up with magnetite nanopowder. The study of the mutual inductance between the current sensor and the primary circuit is carried out through the mutual partial inductance method. Comparison with air core Rogowski coil having the same geometry is developed for different current intensity and operating frequency.

Abstract
In this paper, we investigate the performances of Rogowski coils with superparamagnetic core. Rectangular cross-section cores are built by a 3D printer and filled up with magnetite nanopowder. The study of the mutual inductance between the current sensor and the primary circuit is carried out through the mutual partial inductance method. Comparison with air core Rogowski coil having the same geometry is developed for different current intensity and operating frequency.File in questo prodotto:
