Abstract
This paper describes new criterions for high-speed transmission line protection using the wavelet technique. Based on the representation of the travelling waves through wavelet modulus maxima, the identification criteria for similar transients, such as switch onto unloaded lines and onto faulted lines, are proposed. Simulations are carried out for testing the criteria and the influences of fault location and noise are discussed
