【Abstract】 On the basis of describing the principles of fault range finding with one and two-terminal traveling wave method, the paper mainly discusses the basic theories of wavelet transform and modulus maximal value which are applied in fault range finding of traveling wave. The elemental criteria and the additional criteria of fault generated transient components’ strangeness are also put forward. Lots of simulations proves the validity and accuracy of the scheme presented in this paper.更多还原
