      A novel wavelet transform analysis based adaptive single-pole autoreclosure scheme of EHV transmission systems is presented in this paper. The discrete wavelet transform is adopted to analyse the fault transients caused by the secondary are and permanent faults and the numerical results reveal that certain wavelet components can be ellectively used to detect and identify the fault relevant characteristics in transmission systems. A threshold based decision logic for the wavelet analysis coefficients is used to distinguish the transient and permanent faults, and in the case of a transient fault, to determine the secondary are extinction time. The outcome of the study clearly indicates that the wavelet transform analysis technique can be used as an attractive and effective means of developing an adaptive autoreclosing scheme.
