Abstract :
As a result of the development of the up-to-date methods of signal processing it is now possible to obtain spectrum characteristics for any noise for a specific interval in time. Spectrum analysis which applies the combined time and frequency representations of noise can provide additional information regarding the amplitude, power and energy of frequency components found in a particular signal. This pa-per evaluates the possibility of time-frequency analysis application for overvoltage hazard due to lightning discharges in Distribution MV Cable Lines.
