摘　　要：光学电压互感器容易受到温度影响,其误差特性是实际工程应用关注的焦点。文中首先介绍了几种典型原理的光学电压互感器,建立了光学电压互感器试验平台及试验方案,并针对已经实用化的2种原理的光学电压互感器开展了温度影响试验,提出了电容分压原理的光学电压互感器温度性能较好的观点。Optical voltage transformer is susceptible to temperature. Therefore, the error characteristic of optical voltage transformer has been attracting many attentions. This paper introduced several typical optical voltage transformer, established the test platform and programs for optical voltage transformers. Temperature impact tests have been carried out for two kinds of optical voltage transformers which are used in practice. Based on the tests, we found that optical voltage transformer based on capacitive voltage divider principle performances better in terms of temperature impacts.
