The study provides detailed analyses and appropriate calculations on which the proposal for selecting the grounding method for the MV network star point and 10(20) kV distribution board supplied from the 110/10(20) kV Srd substation is based. The aforementioned proposal for selecting the grounding method is given for the so-called transitional and final operating regime of the associated 10(20) kV network supplied from the 110/10(20) kV Srd substation.
