中文摘要：

光电式电流互感器已经成为国内外研究的热点，其中Rogowski线圈、高压侧电路的供电电源是目前研究工作的重点。在此介绍了有源光电式电流互感器基本原理，叙述了Rogowski线圈采样原理。Rogowski线圈的性能易受外界磁场和环境温度等因素的影响，时Rogowski线圈的制作提出了改进。有源光电式电流互感器高压侧供能问题仍未得到很好的解决，对母线电流取能、电容电流取能、激光供能、太阳能供电几种供能方式进行了研究分析。

英文摘要：

Optical- electronic current transformer is highlighted in the research of current measurement at electric power system,The principle sampling using Rogowski coil is described,the performance of the Rogowski coil is affected by the factors easily,such as magnetic field and the environment temperature. Putting forward the improvement of the manufacture of the Rogowski coil. The power supply in high voltage area of active optical - electronic current transformer isn＇t resolved very well,several kinds of mehod supplying power are analysed.
