description: Topic of the graduation thesis: "The use of wavelet transform to identify single-phase phenomena on the ground." This work is devoted to the study of the possibility of wavelet transform of singularities of single-phase closures. Tasks that were solved in the course of the study: 1. Revealing the type and type of the conditioned wavelet for placing the SPZ. 2. The choice of basic schemes for constructing and connecting the constituent components. 3. Calculation of single-phase earth fault currents. 4. Modeling of the arc during SPE. The detection of the type and type of the causal wavelet was carried out using the Matlab software in the Wavelet Analyzer application. As a result, coarse and complex wavelets, as well as various coefficients of complex wavelets, were analyzed. As a result of the research, it was unambiguously determined that the coefficients are the most suitable.
