| Abstract: | A type of optical current transducer （OCT） of Faraday magnetooptic effect is introduced. From an aspect of prac tical utilization for OCT, the selfhealing OCT is proposed to greatly improve the measuring accuracy and operation stabili ty. According to the standard of IEC 600448, the performance of OCT is validated by detail tests. The results indicates that the proposed OCT has a good linear measuring ability, and the steady state measuring accuracy is better than 0.2% for the temperature range from 40 °C to ＋ 60°C. The field data for several years shows that the proposed OCT has successive measuring accuracy, and its measuring precision is higher than the traditional current transformer. The designed OCT has practical value for engineering application. |
