This study studies the effect of Circuit Breaker Shunt Resistance (CBSR), Metal Oxide Vaistor
(MOV) and Neutral earth Resistance (NR) on the control of ferroresonance in the voltage transformer. It is
expected that NR can controlled ferroresonance better than MOV and CBSR. Study has been done on a one
phase voltage transformer rated 100 VA, 275 kV. The simulation results reveal that considering the CBSR and
MOV exhibits a great mitigating effect on ferroresonance overvoltages, but these resistances cannot control
these phenomena for all range of parameters. By applying NR to the system structure, ferroresonance has been
controlled and its amplitude has been damped for all parameters values.
Key words: Bifurcation diagram, , chaos, Circuit Breakers Shunt Resistance (CBSR) , ferroresonance, MOV, Neutral earth Resistance (NR), voltage transformers
