Abstract :
A novel optical fiber DC current transformer (OFDCCT) with advantages of robustness to the electromagnetic field, flexibility to the install condition, simple structure and electrical insulation has been developed. In this paper, some measurement results which are difficult to be realized by a conventional current sensor are shown. Such results emphasize the advantages of the OFDCCT. Furthermore, the possible future applications of the OFDCCT for the protection relay system are shown.
