Mathematical models of instantaneous fault currents of a three-phase asymmetric network with a solidly grounded neutral for various types of short-circuit are developed. The examples of calculations of the total fault current value show the feasibility of taking into account its decaying load component. Presented recommendations for the calculation of fault currents on the developed models for cases of metal short-circuit and short-circuit with additional resistance at the site of damage. References 10, figures 5, table 1.
Key words: short circuit, instantaneous current, model, high-voltage network.
