This paper presents a new method of visualization of the power waveforms frequency fluctuations in terms of analysis of harmonics and interharmonics in an electric power signal. The presented method is based on image analysis and can be competitive, in some specific cases, to both Fourier transformation and wavelet method. The presented method constitutes a specific image preparation which consists of a split waveform signal. The article shows examples of simulations results for real life and simulated signals.
