Abstract
A noninvasive current sensor for rail installation is presented, starting from the requirement definition and preliminary finite-element method (FEM) analysis. The sensor is complemented with a low-noise large-dynamic-range amplifier; the results of a thorough experimental characterization are presented and commented upon, together with a series of considerations on the suitability of an open-type sensor with respect to external disturbance. The dynamic range and frequency range are quite extended (from 1 mA to 10 kA and 10 Hz to 20 kHz, respectively) so that it may be defined as a high-performance sensor.
