摘要：
The contribution analyzes the impact of distribution power system parameters to magnitude of transients resulting from the single-line to ground faults. For purposes of calculations there was created a mathematical model of 22 kV line supplied from 110/23 kV transformer, in the neutral node of which the Petersen coil was installed. Computation method was based on the solution of the first order system of linear differential equations. The magnitude of voltage transients in non-stationary state was analyzed according to: Petersen coil parameters, place of origin of a single-line to ground fault, and parameters of the HV/MV power transformer.
