CONTROLLED INTERRUPTION METHOD FOR SHORT-CIRCUIT CURRENT IN DC SUBSTATION

In commuter sections, the capacity of substations must be increased to meet increasing traffic volumes; simultaneously the short-circuit current is higher. The result is that overcurrents are likely to surpass the ratings of high-speed circuit breakers. This article attempts to define the characteristics of short-circuit currents in a high-capacity substation and studies methods to suppress and interrupt heavy short-circuit currents by inserting reactors.
