Task 1 The three-phase transformer has following rated data: SN=160 kVA (rated apparent power), Uin=6000V (rate primary winding voltage), U2n=525V (rate secondary winding voltage), fr=50 Hz and Yd5 (vector group of transformer). During experimental measurements two test were executed: (a) open-circuit test and (b) short-circuit test. In open-circuit state the following results were obtained: I6=1.25 A and Po=1.6 kW. During short-circuit test the following values were measured: U=270 V (short-circuit voltage), P.4.16 kW (the power loses in short-circuit state). Please draw the equivalent circuit of the examined transformer and calculate all equivalent circuit parameters.
