Abstract
In this paper an electron-optic current transformer (CT) is described which is used in measuring the super-voltage station's line current. The measurement system uses 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 result showing current measurement by means of CT.
