| Abstract: | The principle of optical system for measuring large electric current by utilizing Faraday magneto-optical effect is stated. With the method of Jones matrix, formula for measuring large current is derived. An optical system for measuring large current is presented. In addition, laboratory tests have been done and the experiment result is given. The error of the measuring system is discussed comprehensively and systematically. The study shows that this measuring system has many advantages over traditional method, such as good electric isolation, immunity to electromagnetic interference, widely dynamic range and high accuracy. Therefore, it is expected to be used for measuring large current in electric systems in the future. |
