摘　　要：通常情况下,配电网电容电流是决定是否装设消弧线圈、确定消弧线圈容量和进行消弧线圈调谐的重要依据,因此有必要进行配电网对地电容测量方法研究。文章首先介绍了现有的3类主要的配电网对地电容测量方法,然后概略分析了各种对地电容测量方法的优缺点及适用范围,并在此基础上阐述了目前对地电容测量中存在的问题并对未来新测量方法进行了展望,可为现场对地电容测量方法的选择提供参考。Usually the capacitive current of the distribution network is to decide whether to install Petersen coil, determine the arc suppression coil capacity and an important basis for Petersen coil tuning. Were summarized and summed up three kinds of capacitive current measuring methods： one is the direct method of direct grounding through the metal lype capacitance current measurement; one is by calculating the capacitance by measuring the electrical parameters of the signal injection two times voltage transformer; and one is in the neutral point of the series parallel electrical components change the calculation of the electrical parameters of capacitor. This paper introduces the three main types of capacitive current measuring methods, the paper briefly analyzes the kinds of capacitance measurement methods advantages and disadvantages and the scope of application, on the basis of the existing problems in the measurement of capacitance current and fixture new measurement methods are discussed. for the measurement method of capacitive current site selection Provide reference.
