    You may use the formula on page 1 in this document http://www.ecse.rpi.edu/courses/EI/transformer_notes.pdf
    However I try to avoid simulating transformers in Spice. Unless I have all the transformer data at hands. Most often you will only have a given secondary voltage at a a given primary voltage and max load current
