Air-cored current-limiting inductor（CLI） is used to limit the magnitude of fault current in 500 kV power systems.Before manufacturing the CLI
the over-voltage withstand ability of CLI should be evaluated to ensure the voltage between two coils less than the withstand value.Therefore
the distribution circuit of CLI is solved with PSCAD/EMTDC based on the known distribution parameter of CLI in this paper.The results show that the maximum voltage between the two first coils under lightning surge is 19.8 kV
and under switching is 10 kV
both of which are less than the withstand value 36 kV.
