Abstract:The properties of dyadic wavelet transform and the algorithms of decomposition and reconstruction of wavelets are discussed. In particular. the relation between fault features of transient current travelling wave and modulus maxima of its wavelet transform is studied. so as to provide a theoretical basis for the fault Phase selection based on travelling waves.
Keywords:dyadic wavelet transform travelling wave fault phase selection
