n this study, we present the propagation of electrical tree in solid insulation via dynamical simulation with cellular automata. Taking a specimen of XLPE dielectric situated between two electrodes under DC voltage. Electrical tree emanates from the end of the needle where the electric stress reaches the dielectric strength of the dielectric material. The potential distribution is determined at every step due to the boundary changes according to tree advancement by resolving Laplace's equation. The effect of the applied voltage levels on the formation of the electrical tree is investigated. The obtained results are in agreement with the available experimental data and published technical literature.

W tym badaniu przedstawiamy propagację drzewa elektrycznego w izolacji stałej poprzez dynamiczną symulację z automatami komórkowymi. Pobranie próbki dielektryka XLPE umieszczonego między dwiema elektrodami pod napięciem stałym. Drzewo elektryczne emanuje z końca igły, gdzie naprężenie elektryczne osiąga wytrzymałość dielektryczną materiału dielektrycznego. Rozkład potencjału jest określany na każdym kroku ze względu na zmiany granic w zależności od postępu drzewa poprzez rozwiązanie równania Laplace'a. Zbadano wpływ przyłożonych poziomów napięcia
