Abstract：Applying the frequency characteristic of ferrite cores, this paper investigated the effects of ferrite cores suppressing radio interference produced by the DC transmission line corona effects. Laboratory test results showed that it was very effective to put ferrite cores around the DC conductor for suppressing radio interference. For both the positive line and negative line, this method had the similar inhibition effect. And the material of ferrite cores affected the restrain result.
