Abstract

A high voltage DC breaker apparatus configured to break a fault current occurring in a high voltage DC conductor includes a current limiting arrangement having at least one section with at least one semiconductor device of turn-off type and at least one arrester connected in parallel therewith, and a mechanical DC breaker connected in series with the current limiting arrangement and including a mechanical switch. The mechanical DC breaker is configured to enable breaking of a fault current in said DC conductor once said semiconductor devices of said arrangement have been turned off.
