Abstract :
The use of modern advances in digital processing methods for the analysis of signal disruption of a non-stationary or quasi-stationary allowed to show the evolution of time-frequency signal along the time axis and the frequency, the discrete signal decomposition. The paper points to the possibility of assessing the risks of isolation medium voltage cables using time-frequency decomposition surges of various origins.
