Popis:	A mathematical model is proposed that allows simulating the currents in the transformer windings during turn shorting when the supply voltage is unbalanced in any load mode. The results of simulation of currents in windings and shorted coils depending on their number in the primary winding in the idle and load modes are presented. Verification of the adequacy of the model by comparing the results of calculation and experiment for the TT-6 transformer showed that the error in simulated currents when shorting a small number of turns does not exceed 10% and meets the requirements of relay protection.
