摘要： A plant for transmitting electric power includes a high voltage DC line, a DC breaker connected in series therewith and configured to break a fault current upon occurrence of a fault, a device configured to detect occurrence of a fault current, a control unit configured to control the DC breaker for protecting equipment connected to the DC line upon occurrence of the fault current and a device configured to dissipate energy stored in a faulty current path of the DC line between the location and the device's upon occurrence of the fault to the moment of the control of the DC breaker. The energy dissipating device includes a series connection of an energy consuming braking resistor and a free-wheeling rectifying member connected between ground and the DC line to conduct current while forming a free-wheeling path therethrough upon the control of the DC breaker upon occurrence of the fault.
