Remote Measurement of Electric current Using Magneto-Optic Technique

The paper deals with the details of an interesting technique which helps in the remote measurement of Electrical current using magnetic and optic devices. Major advantage of the presented technique is the isolation of measuring system from the actual power circuit. It will help in the repair of measuring system without closing the main circuit which is a crucial requirement of supply system. It has been successfully used for the measurement of current up to 75 A.
