Paper Abstract

This paper presents an optical measurement method of transient current. The current is induced by a Rogowski coil, and the induced voltage together with other constant source is used to drive a linear LED and make the light be modulated by the current. The modulated light is transmitted to electronic circuit by optical fiber and converted to voltage signa. A microcontroller processes the signal and types the current waveform.
