Effect of initial conditions on chaotic ferroresonance in power transformers

The solution of a nonlinear equation for a typical ferroresonant circuit containing a power transformer is shown to be dependent on the value of its initial conditions. It is also shown that a small change in initial conditions leads to a large difference in long-term behaviour of the system, and this makes the future of the system unpredictable. With detailed analysis of many simulation results, the basins of attraction for different chaotic regions of the system are obtained
