Abstract

At present, in field of high voltage engineering and of high voltage measurement, while studying frequency spectrum of high voltage impulse the forms of lightning are always interested more than switching impulse voltage (yes or no, only 250/2500 s form) and was applied direct Fourier transformation with two frequency spectra: amplitude- and phase- frequency spectra. This article, the first time, studied frequency spectrum of inverse Fourier transformation for high voltage non-periodic switching impulses and from this some interesting results were obtained.
