Abstract
This work introduces a short-circuit current device (SCCD) for low voltage DC grids. This device aims to provide a fault current for protection devices which require an overcurrent for a rather long period in order to trip, e.g. melting fuses, in grid installations where such currents are usually not available because of converter current limits and smaller grid-side capacitors.
