Hopefully this has not already been asked. It would be hard to do a forum search with the right words to find it if it has been already. I am wondering if it is ever possible or common place to generate power in a Wye generation scheme and then connect it directly to a transformer with a Delta primary. If this is done, what would be the major setbacks. Also, how would one MCOV ratings of elbow arrestors at the high side of a transformer?
