Description	Příspěvek se zabývá porovnáním dvou publikovaných přístupů k modelování transformátorů v elektrických sítích. Je provedeno zhodnocení možnosti využití obou přístupů pro simulace konkrétního přístrojového transformátoru napětí. (cs) The paper deals with a comparison of two published approaches to modelling the properties of magnetic circuits leading to a dynamic description of hysteresis characteristic. The comparison of the two methods is carried out both theoretically and in practical measurements on instrument voltage transformer. The paper also deals with the possibility of employing the models for ferroresonance simulations in power systems. What is common to both models is the way they are obtained, namely from measuring in oversaturated region (as far behind the bend of magnetization characteristic as possible). Model 1 can be seen as more faithful. Practical experience shows that a reduction of the losses in magnetic circuits of transformers is ever more frequently accom panied by the appearance of ferroresonance phenomena in power networks. It is obvious that it will be necessary to include the calculation of ferroresonance phenomena in the methodology of designing MV and HV facilities.
