在电力系统中,除了电场的计算方法外,电场的测量也是一种很重要的手段。在一些特殊的场合,测量甚至是唯一的方法。介绍了一种可用来测量随时间周期性变化或瞬变电场的球形传感器,对球形探头测量电场的基本原理和一、二、三维电场探头的结构及测量误差做了分析,并介绍了二维球形传感器测量系统及其应用。关键词: 瞬态电场; 探头; 电场测量Abstract : In power system ,beside field calculation ,the measurement of electric field is an important method. In some special case ,measurement is the only way. It is described that an electric field sensor for the measurement of time dependent periodic or transient electric fields. The basic theory of the measuring method and the geometry of the three kinds probes are described ,and the field measurement system with spherical sensor and its application are emphasized.Key words : transient electric field ; probe ; electric field measurement
