Hi !!

We are planning for a 380 v 60 hz generator supply for a farm of 5000 kva load.

We have to step-up the 380 volts supply fron gens to 13.8kv for distribution in remote areas of farm.

The transformers i am planning is 380volts to 13.8kv Ynd11 for stepup and 13.8kv Dyn11 stepdown at load point.

Please suggest whether this setup of transformer connections choice is correct

The gens 4 X 1600 kva will be in -sync.

What the advantages and disadvantages of using Ynd11 transformer at gen output?
