摘　　要：通过对500kV光学电压传感系统在工频高压下的传感特性测试，研究了光学电压传感器在垂直位置、上部法兰高度等变化时对测试参数大小、灵敏度、线性度，稳定性的影响．实验研究表明：垂直位置的变化、上部法兰高度的变化都会对测试值有显著影响；下引电极或下置电极的引入能有效地调整和改善测试灵敏度；光学电压传感系统测试值与外加电压有较好的线性关系。Test results on 500 kV optical voltage tansducersystem are obtained by power frequency high voltage testsin hish voltage laboratory. Different effects such as the ver-tical position and the beight of the upper flange on the mag-nitued, sensitivity, linearity and stability of the optical mea-surcments are studied. The results show that the variationsin the vertical position and the height of upper flange mayaffect the measurements significantly.
