| Abstract: | Many inconveniences reveal in the coordination of traditional electro magnetic current transformer with microcomputer based protective devices. The appearance of optical current transducer (OCT) offers new solution for this problem. In this paper at first a comparison of OCT with electro magnetic CT is presented, then the working principle of OCT and the detection method of its signal are presented. It is pointed out that the OCT and microcomputer based protective device should be interfaced by digital signal and the progress in this field is introduced. Surely, the principle, performance and hardware of future protective relaying will be influenced by the application of OCT to it and the development of protective devices will be promoted. |
