Answer / Durgesh Kumar Jha

a) The resistance between each conductor in a 16 kV or 25 kV DTRA installation is typically low and can be found in the technical specifications provided by the manufacturer. nb) Between conductor to earth, the grounding resistance should meet the requirements specified by applicable codes and standards (e.g., IEEE).nc) The installation resistance for each apparatus or conductor cannot be generalized; it depends on factors such as the type of equipment and cable lengths.nd) Earth resistance for the system of earthing is typically measured during the commissioning process, taking into account factors like soil resistivity, ground electrode layout, and system configuration.
