CHAOTIC FERRORESONANCE IN POWER TRANSFORMERS

The solution of the nonlinear equation for a typical ferroresonant cir cuit containing a power transformer is shown to be dependent on the ac curate description of the magnetisation curve. A detailed analysis of many simulation results demonstrates that the probability of chaos inc reases as losses decrease and the nonlinearity of the transformer magn etisation 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 ste ady-state chaos is also discussed.
