Abstract
The paper introduces protection of complete switchgear cells against arc faults which controls the ratio of the unbalanced currents of zerosequence current filter and zero-sequence current transformer. The examples of its implementation on a semiconductor elements and software are given. The analysis of work in different modes and the methods for selecting settings and evaluating the sensitivity are proposed.
