Simulation study of the LV neutral circuit for identifying its transfer potential and input impedance

This paper deals with the identification of input impedance of low voltage (LV) neutral circuit obtained by simulation study. This input impedance affects the transfer potential at LV customers caused by faults on medium voltage (MV) or high voltage (HV) systems. Transferred potential causes many damages in electronic equipments of LV customers year by year in Hungary [1]. Furthermore, the results of this simulation study assist to clearly know the relative importance of different parameters which are affecting transfer potential.
