| 摘 要： | 提出了一种新的快速暂态过电压（ＶＦＴＯ）测量方法－微分积分方法，其特点是不需对ＧＩＳ作任何改造。在同轴传输单元上对研制的微积分系统的响应特性进行了校验，并首次在国内５００ｋＶ的ＧＩＳ上进行了ＶＦＴＯ实测，测量结果与分析计算一致，表明微积分系统是一种较好的ＶＦＴＯ测量方法。

| Abstract: | A differentiating/integrating(D/I) system, which does not change Gas Insulated Substation(GIS) configuration, is developed for the field measurement of Very Fast Transient Overvoltages(VFTO) occurring in GIS. The D/I system transfer characteristics are measured on a coaxial transmission system. Step response experiments show ideal performance of the D/I system. VFTO is measured using the D/I system in a 500kV GIS. Field VFTO measurements show that the D/I system has the advantages of not influencing GIS service and convenient installation. |
