LOW-COST CURRENT TRANSDUCER BASED ON CIRCULAR ARRAY OF MAGNETIC SENSORS

Angelo Manara, Luca Di Rienzo, Roberto Ottoboni
  • Abstract:
    A Low-cost current transducer based on circular array of magnetic sensors is proposed as a valid alternative to traditional current transformers for high-current industrial applications in poly-phase systems of conductors. Since the accuracy of a circular array can be limited by the effects of magnetic fields of nearby phases and by those of eddy currents in the conductors, a new method for the compensation of those effects is proposed in an analytical formulation and is experimentally investigated.
