There are several models for magnetic hysteresis. Their key purposes are to model
magnetization curves with a history dependence to achieve hysteresis cycles without a …

One of the weakest components of modern transient simulation software is the transformer
model. Many opportunities exist to improve the simulation of its complicated behaviors …

With the fast-paced changing technologies in the power industry, new references
addressing new technologies are coming to the market. Based on this fact, there is an urgent …

In the computation of magnetic fields for rotating electric machines, transformers, and
reactors, the hysteresis nonlinearity sometimes has to be taken into account. Nowadays …

The modeling of power transformer faults and its application to performance evaluation of a
commercial digital power transformer relay are the objectives of this study. A new method to …

This two-part paper is intended to clarify definitions in dual transformer modeling that are
vague, provide accurate modeling guidelines, clarify misconceptions about numerical …

This paper proposes a model of core-type distribution transformers for electromagnetic (EM)
transient studies. The model accurately reproduces not only the impedance characteristics …

Transformers are the most important components of transmission and distribution systems.
For transformers the geometrical data is only available to the manufacturers and it is …

A new dynamic model of a three-phase three-leg transformer for steady-state and transient
operating conditions is proposed in this paper. With very few exceptions, the existing models …

The main features of the history-dependent inverse model of magnetic hysteresis are
outlined. Its implementation into the Electromagnetic Transient Program-Alternative …
