Protection system from overvoltages in 10 kv network

Abstract

To avoid of burned wires, fire and overvoltages caused by single phase grounding of high voltage supply line with insulated neutral it was investigated and created technical equipment to determine location of single phase grounding and to shunt a fauted phase to grounding mesh of substation. An automated system is based on circuitbreaker with separately controlled contacts by cylindrical linear induction motors and control equipment. [...].
