Hi,(adsbygoogle = window.adsbygoogle || []).push({});

If there are no resistance and impedance parameters given for a single phase transformer, is it possible to work out the values of primary and secondary winding inductance and resistance (r1,r2,re1, x1,x2,xe1 etc) without the use of a short circuit test. The transformer can be tested open circuit to allow core losses and mag current to be found, but if there is no short circuit test conducted, can these parameters be found? I think it is impossible but i would like clarification
