Abstract

Current measurement is required to ensure the correct operation of power systems. Conventional current transformers are still widely employed in such networks but their well-known limits make them not suitable for the incoming smart meters. In this paper, a current transducer based on proper measurements of the magnetic field produced by the primary current is proposed. Its main feature is the particular geometry that allows neglecting the effect of external fields without using traditional coil-structure.
