- Abstract:
- Giant Magneto-Resistive (GMR) sensors are solid state sensors suited to detect magnetic fields produced by variable currents. In this work, a GMR sensor is used in a contactless fashion in order to measure current from a load or from a power line distribution cable in order to detect perturbations or disturbances. The aim of this work is to demonstrate the feasibility for using this technology for current measurement in manufacturing field. Results shown that GMR technology is competitive with respect to other technologies and can be useful in health monitoring of industrial equipment
