We present a ruggedized portable fiber-optic Faraday-rotation current sensor, that exhibits good and stable performance characteristics. The sensor has been tested and calibrated against a commercial induction-coil type device. The resultant scale-factor is in a very good agreement with the theoretical one, calculated following extensive fiber birefringence measurements. The measured sensor noise equivalent current is 0.23Amp/√Hz.
