【 摘 要 】

The paper deals with the development of an interesting technique which can help in the remote measurement of electrical current, using magnetic and optical devices. Major advantage of the presented technique is the isolation provided by Hall sensor as well as by the optical devices 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. Output of the optical receiver is interfaced with the microcontroller to display the current as well as to instill intelligence to the system. It has been successfully used for the measurement of currents up to 60 Aand relationship between current under measurement and output of the system is appreciably linear.
