Abstract

This article discusses the possibility of reducing the levels of single-phase short circuits in HV networks. Since over 80% of all short circuits are single-phase. The dimensional condition for the equipment in the HV switchgears is a three-phase short circuit, as a result of which the currents of single-phase short circuits are inadmissible to be greater than the currents of three-phase short circuit. Reducing the currents of single-phase short circuit will increase the service life of the circuit breakers.
