It is commonly recognized that correct transformer model (particularly topological one) is a
key element for any ferroresonance simulations. This paper represents a line of reasoning …

In this paper, Finite Element Method (FEM) is used to study the ferroresonance phenomenon
from the perspective of the electromagnetic forces introduced on the transformer windings. In …

The actual high incidence of the low-loss power transformers in the modern electric and
electronic installations, increase the risk of the ferroresonance occurrence. This could be …

The validation of power system component models for transient analysis implies the use of
data recorded from either field measurements or laboratory tests. This task can be …

This paper performed the ferroresonance experiment with configuration of capacitance
series and shunt to 1 kV transformer core type H and 1 kV transformer core type M. The …

Ferroresonance is a phenomenon that occurs in low loss transformers under certain
conditions. Recent developments have led to the introduction of amorphous core materials …

1.1 INTRODUCTION erroresonance is a general term applied to a wide variety of
interactions between capacitors and iron-core inductors resulting in high overvoltages and …

In this work, saturation and hysteresis loops are included in a four-port transformer model for
electromagnetic transients computation in the frequency domain. Approximations with linear …

Ferroresonance is a non-linear and complex electrical phenomenon that is due to the
interaction between the capacitance of a cable, or overhead line, connected to the …

In 2019, an article published by Geldenhuys and Padayachee reported unexpected
overvoltages during the commissioning phase of distribution transformers. Consequently …
