Abstract

Earth fault current frequency exceeding 50/60 Hz has a negative effect on tripping of residual current devices. For higher frequency real tripping current of residual current devices moves towards higher values. In some cases the devices may not operate at all. Main sources of the improper tripping of residual current devices for higher earth fault current frequency are discussed. The solution which makes it possible to eliminate the negative effect of higher frequency is presented. Ill. 10, bibl. 5 (in English; summaries in English, Russian and Lithuanian).
