Abstract
In this paper, at first non-conventional ferroresonance phenomenon is introduced, then various typesof ferroresonance in a potential transformer is simulated. So, effect of circuit breaker shunt resistance on controlling chaotic ferroresonance in a potential transformer has been studied, it is shows that for some parameter value this resistance cannot clamp the ferroresonance overvoltages in potentialtransformers. Finally effect of neutral earth resistance on the controlling these oscillations has been investigated. The proposed approach was implemented using MATLAB, and results are presented. It is concluded that this resistance generally can cause ferroresonance decreasing. For confirmation this aspect simulation has been done on a one phase potential transformer rated 100VA, 275kV. The simulation results show that considering the neutral earth resistance on the system configuration, shows a great controlling effect on ferroresonance nonlinear overvoltages.
