5. 6. 7. 8. Determine the % voltage regulation of the transformer. (2) Explain why the input power factor varies with the different loads while the output power factor stays constant. (4) Determine (a) the rated primary and (b) the rated secondary current. (4) Determine (a) the equivalent resistive component and (b) leakage flux component of the winding on the high voltage side in ohm. Determine (a and b) the values of the resistance's (R1 and R2) and (c and d) the values of the reactance's (X1 and X2) from the tests. (Take R1/R2 = X1/X2) (11) Determine (a) the core loss resistance and (b) the magnetizing reactance of the core in ohm. (9) (6) 9. 10.
