要約(英語): Surge voltages often have much higher value and changing rate than those of power frequency voltages, and might cause damages to apparatuses or equipment not only on near a surge source, for example lightning struck point, but also on far points from it due to propagating. In addition, surge phenomena often become complex due to the reflections and the superpositions on a point where surge impedances having different value are connected. The surge phenomenon occurring on a power cables connected with a transmission tower is one of these cases. This research's goal is to propose the EMTP model for surge phenomenon occurring on cables arranged through a transmission tower. The proposed model simulates such cable by using a cable model through a pipe conductor. The results calculated by the proposed model ware compared with the results by VSTLrev (Virtual Surge Test Lab. Restructured and Extended Version) which is a surge analysis program based on FDTD (Finite Difference Time Domain) method to verify the accuracy of the proposed model. As a result, the proposed model is reasonable for analysis of a surge phenomenon occurring on a cable through a transmission tower.
