short circuit calculation
(OP)
Hello Everyone!
How can I calculate the single phased short circuit current on the primary side of a Yd-connected transformer?
I know that a Dy-connected transformer single phase short circuit turns into a two phased current, but what about the other way around???

RE: short circuit calculation
The available fault current on the primary side would be determined by the upstream system.
Unless. . . are you're concerned about motors on the secondary side backfeeding into the primary side through the transformer?

I have a grid consisting of the utility which has a grounded network. I am a consumer with a Dy-connected transformer with a generator connected to the secondary side. I there is a single phase short circuit on the high voltage side what would the contribution the fault be from my generator??
