This paper employs the multiple scales method and

chaos theory for analyzing chaotic behavior of the voltage

transformer (VT) with linear core loss model. It is shown that

ferroresonance phenomenon in VTs can be classified as chaotic

dynamics, including a sequence of bifurcations such as period

doubling bifurcation (PDB), saddle node bifurcation (SNB),

Hopf Bifurcation (HB) and chaos.-This paper employs the multiple scales method and
