Chaos in ferroresonant wound voltage transformers: effect of core losses and universal circuit behaviour

Ferroresonance Phenomena in Unloaded TransformersApplying MOV

“…Paper in [17] investigated the effect of transformer modeling on the predicted ferroresonance oscillations. Using a linear model, [18] have brought the effect of core loss in damping ferroresonance oscillations. In [19] emphasizes treating core loss as a nonlinear function of voltage on transformer.…”

Circuit Breaker Shunt Resistance Effect on Ferroresonancein Voltage Transformer Including Nonlinear Core Losses

“…The mitigating effect of transformer connected in parallel to a MOV arrester has been illustrated in [11]. Analysis of ferroresonance in voltage transformer has been investigated by Zahawi in [12] and [13]. Analysis of ferroresonance phenomena in the power transformers including neutral resistance effect has been reported in [14].…”

Effect of Metal Oxide Arrester on Chaotic Behavior of Power Transformers

“…authors of Ref. [12] have indicated the effect of core loss in damping ferroresonance oscillations. The importance of treating core loss as a nonlinear function of voltage is highlighted in Ref.…”

“…Evaluation of chaos in voltage transformer, effect of resistance key on the chaotic behavior voltage transformer and and subharmonics that produced with ferroresonance in this type transformer are studied in Refs. [20][21][22][23]. In all of done researches until now, the effect of Metal Oxide Arrester on the chaotic ferroresonance behaviour of power transformer with nonlinear core loss model have not be done.…”
