Answer / k.prakashchandra

The resistance is infinity if the TR secondary neutral is
not earthed and it is zero if you use the same earth
conductor for Tr neutral earthing also. Further if you have
separate earthings for TR neutral and the earth conductor
,the resistance measured would be the sum of their ER
values, ignoring resistance of the conductors

Will it be OK to connect a 5MVA 33/6.6kV Ynd11 Transformer to a Star connected Motor. Or on other words connecting a Delta to a Star. I have another 30MVA 33/11 Dyn11 and would it be practical to convert it to Dd0 consequently converting the Voltage Ratio to 33/6.35kV Dd0.
