Abstract
This paper presents a new method to diagnose faults in a transmission system This is based on detecting high frequency components contained in a fault signal spectrum The discrete wavelet transform (DWT) is used in the analysis in order to classify fault types and to locate fault positions Simulations are performed using ATP/EMTP It is found that the proposed method gives satisfactory results, and will be very useful in the development of a power system protection scheme
