Abstract

The principle of optical method for measuring electric current utilizing the Faraday magneto-optical effect is stated in the paper. A practical power source of semiconductor laser diode is presented, the sensing head designed by ourselves is introduced. The signal processing technique with one chip microcomputer is described. In addition, the experimental results are given. The study shows that this method has many advantages. Therefore, it is expecting to be used in electric system in the future.
