Abstract

The device according to the invention is adapted to protect, in an electric power plant, objects (1, 7, 27) against fault-related over-currents, said objects being connected to an electric power network (3) or another equipment in the electric power plant. An over-current reducing arrangement (5) is connected to a line (2), which interconnects the network/equipment (3) and the object (1, 7, 27), said arrangement being actuatable for over-current reduction with the assistance of an over-current condition detecting arrangement.
