"The parameters of power transformers are usually determined from the results of the short-circuit test and open-circuit test, i.e. the user knows active powers, the amplitudes of currents and voltages in both situations. The aim of this paper is to present approximate formulae for \u201Ccircuit theory\u201D type of equivalent circuits of the chosen diagram. Exact formulae for parallel and serial resistances and self and mutual inductances are not available and probably cannot be obtained in a closed form." . .
