Answer / rams

Appliances rated voltage is 415V. If Trasformer is specied
at 415V, it will further drop down at receving end and
appliances may not work
To compensate Voltage drop at receiving end

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.
