Abstract
The solution of the nonlinear equation for a typical ferroresonant circuit containing a power transformer is shown to be dependent on the accurate description of the magnetisation curve. A detailed analysis of many simulation results demonstrates that the probability of chaos increases as losses decrease and the nonlinearity of the transformer magnetisation rises. The effect of varying the transformer core losses and the value of the source voltage on the chaotic solution of the system has been studied. The concept of transient chaos as compared with steady-state chaos is also discussed
