In Medium Voltage (MV) applications, innovative solutions for voltage and current measurements are investigated in this last years. In particular, technical solutions characterized by proper metrological performance and at the same time small size, low cost, and simple integrability with communication networks are followed with the aim of operating within the modern industrial context and in the smart grid. In these scenarios, the paper describes a current transducer thought for industrial applications and based on a cheap commercial AMR sensor. A deep experimental analysis is carried out to verify the metrological performance of the proposed system for both Direct and Alternate Current operating, and to verify the influence of the environmental temperature on the input-output characteristic. The obtained results have shown that the proposed system allows reaching metrological performance suitable for typical MV applications if the temperature compensation is carried out.
