BALANCED FRONT-END ELECTRONICS FOR ROGOWSKI COILS

L. Di Rienzo, A. Ferrero, R. Ottoboni

Abstract

The main advantages of the Rogowski coils are the Potential free measurement and the low cost compared to shunt and CT measuring systems. Usually they are applied for measuring high-amplitude or high frequency currents. The aims of the paper is to investigate a new analog signal processing able to overcome the major limitations of the Rogowski coils in low current and lowfrequency range.
