Detection, classification, and location of faults in power transmission lines
International Journal of Electrical Power & Energy Systems, 2015 This paper presents a pattern recognition approach for current differential relaying of power transmission lines. The current differential method uses spectral energy information provided through a new Fast Discrete S-Transform (FDST).
