Resumen
In this paper a low-cost all-fiber current sensor is described that fulfills the requirements of robustness, sensitivity,
accuracy and cost required for the monitoring of catenary current in changeover sections of the high-speed railway
network. Its optical configuration is simplified through the use of few devices with extremely simplified alignment. This
allows high sensitivity for low current values and a resolution below the ampere level. The sensing head is packed in a
compact box withstanding temperature and position variations without affecting the sensitivity of the set-up. The
electronics incorporates self-referencing that makes it robust to small misalignments and power variations in the optical
source. Field tests will be reported in the conference
