【Abstract】 In this paper, the working principles and fabricating methods of hybrid large current fiber sensor have been described. The hybrid large current fiber sensor consists of a LED as light sourse, PIN as light receiver, flint glass as magnetic inductor and multimode fiber as light conductor. This sensor can be used for monitoring the current in high voltage electric net and the applied range is 102-104A with accuracy of ±0.5%.更多还原
