Abstract: A full optical fiber current sensor (FOCS) is developed in order to monitor the current on the transmission line, which is based on Faraday effect and magnetostrictive principle. This FOCS can measure the current accurately. By the use of zigzag modulation signal which is of innovate, the current in the range of 40 A to 140 A is measured. The experimental data meets the actual current accurately.
