Hi,

I want to model a Dyn5 transformer. I have tried setting the ang1 value to 150 and the connection code to 3.

No problem with connection code 3, but the load flow refuses to solve for ang1=150.

I want to do this in order to get the phase angles correct in a fault level calculation. The load flow is actually of no interest to me, just a means of getting to the result.

What are my options? Is it necessary to set ang1 at all or is it enough with cc=3.
