This paper presents a new algorithm for fault
classification in transmission lines using Discrete Wavelet
Transform (DWT). The proposed algorithm uses detail
coefficients of three phase currents as well as their combination
as criterion to classify faults and identification of faulted phases.
In order to evaluate the proposed algorithm a 400 kV
transmission system which is a part of Iran transmission system
is simulated using EMTP-RV and the voltage and current signals
are analyzed in MATLAB software. The results indicate that the
proposed algorithm is very reliable and accurate
