Unformatted text preview: I prated 12.547A = kVA kW â‰¡ kVAR kW â‰¡ Problem 5-8: Solution S rated 100 kVA â‹… = V prated 7.97 kV â‹… = V srated 240 volt â‹… = Voc 240 V â‹… = I oc 12 A â‹… = P oc 1200 W â‹… = V sc 500 V â‹… = I sc 12.5 A â‹… = P sc 1500 W â‹… = a. Rated current flows on the high side of the transformer during the short circuit test, thus I hrated I sc = I hrated 12.5A = alternatively, we can calculate the rated current by dividing rated power by rated voltage I prated S rated V prated =...
