Keywords: Transient analysis , Fault currents , Conductors

Abstract: The paper investigates the change of the earth fault current in medium voltage electrical grids grounded through an active resistance. Grids with different percentages of cable lengths are considered. For the purpose of the study, simulations of medium voltage electrical grid were made. The maximum value of the currents in transient mode and the duration of the process, the magnitude of the current of a single line to ground fault in the steady state mode with the change of transient resistance and the location of the fault are investigated.
