Abstract

This article discusses the issues of single-phase automatic reclosing (SPAR) in a 500 kV line with parallel half-phases. An algorithm is being developed for calculating secondary arc currents and transientrecovery voltages. The features of the implementation of SPAR in case of accidents at half-phases and working phases are clarified
