摘要：
Due to the opening or closing of circuit breakers and disconnect switches in Gas Insulated Substations (GIS), Very Fast Transient Over-voltages (VFTO) are generated, which will bring an instantaneous change in voltage with a very short rise time and it is normally followed by oscillation having high frequencies. This paper describes the variations of VFTO magnitudes transformer bushing of a 765 kV GIS during different switching operations have been calculated and compared by using EMTP.
