# Synchronous Generator Ratings

 P: 767 Hey all, If we are given a synchronous generator with the following nameplate values 10MVA, 13.8kV, 2 pole, 60 Hz why is it not sufficient to go $$S_{RATED}=I_{RATED}V_{RATED}$$ as we did for transformers? My reason for asking is because I am trying to determine the voltage regulation of a particular generator. However, if I determine the full load current using the above formula, I get an absurd result.
 Sci Advisor PF Gold P: 2,633 Is the generator a 3 phase machine? If so, the apparent power = √3 Voltageline ⋅ Currentline. 13.8kv is a line voltage.
 P: 767 How silly of me. Honestly, this entire time my issue was that I did not divide S by three. Thanks!
