ABSTRACT
It is o¢en assumed that any grounded object can be safely touched. A low substation ground resistance is not, in itself, a guarantee of safety. ere is no simple relation between the resistance of the grounding system as a whole and the maximum shock current to which a person might be exposed. A substation with

relatively low ground resistance might be dangerous, while another substation with very high ground resistance might be safe or could be made safe by careful design.
