摘要：

In this paper an electro-optic current transformer (CT) is designed which is used for measuring the super-high-voltage station's line current. The measurement system utilizes a conventional CT as the sensing probe whose electronics is optically powered. The paper describes the principle of measurement system, including the system design, optically powered sensing probe, the data link measurement signal processing and results showing current measurement by means of CT.
