Study of Current Status and Development of Photoelectric Current Transformer Technology

Aiming at photoelectric current transformer technology, this paper analyses the principle of passive and active transformer firstly, then discusses the main technical difficulties in this area currently and the development of optical current transformer. We hope all above can play a reference role for related work. With the gradually deepen theory research on photoelectric current transformer technology in domestic and the continuous improving achievements acquired in practice, it's necessary to study the current status and development of photoelectric current transformer technology.
