what winding configuration of generator step-up transformer is most used in North America when generator is connected to LDC feeder?
delta on HV side or delta on LV side?
I found some threads that are useful but can't read it because there is no "left and right scroll" in the bottom og the page. So text is cut off. Have you been able to fix this?
example is Feb 2006 thread named:" Advantages and Disadvantages of Delta-Wye and Wye Delta ... )
Generator transformers are mainly delta connected on primary (for reduced phase currents and easier winding manufacture) and wye connected on secondary (for reduced phase voltage with resultant less stringent insulation requirement).
