Abstract: In order to realize the fast and accurate classification of high voltage transmission line fault, a fault classification scheme is proposed based on fault voltage signal amplitude and SVM. The half-circle fault amplititudes of threephase voltage intercepted after filtering just are applied as fault features in the novel scheme, being input to SVM intelligent fault classification system. After training and predicting, the scheme can identify fault types on
transmission line. According to system simulation results, the fault classification method can effectively improve the speed and the accuracy of fault classification, which is lightly affected by factors such as fault impedances,fault inception angles, fault location and so on. It has good adaptability and the accuracy of fault classification can reach 100%.
