On the basis of the constructed computer model, the process of a single-phase earth fault in the power supply system of agricultural consumers with a dead-grounded neutral was studied. As a result of the analysis of the model of the power supply system in the single-phase short circuit mode, the phenomenon of a sharp-pointed voltage pulse of negative polarity, arising at the moment of protection operation, was revealed, which negatively affects the electrical equipment of agricultural consumers.
