摘　　要：论述了用于电力系统状态监测的光纤电场传感器的测量原理 ,给出了测量系统的光路结构。应用所设计的装置实测交变稳定电场 ,实验表明 ,测量系统线性度良好 ,约0 .3% ,几乎无迟滞误差 ,相对误差 <± 0 .5 % ,稳定性良好 ,满足电力系统或电器设备检测电场的要求。This paper describes the measuring principle of optical fiber electrical field transducer used for condition monitor of electric power system, and gives the structure of the measuring system. The practical measurement for the steady-state alternating current electric field is taken. The test results show that the measuring system has excellent linearity with about 0.3%, nearly no hysteresis, less than 0.5% relative error and good stability, and satisfies the requirements of electric power system and electrical apparatuses.
