摘要：
A differentiating/integrating (D/I) system which does not change GIS configuration is developed for the measurement of very fast transient overvoltages (VFTO) occurring in GIS. Then the numerical computation of VFTO is studied on the base of field measurement results. Some factors influencing VFTO magnitude are analyzed through computation. The possible reason why VFTO may cause more failures in 330kV and above GIS is presented.
