Abstract (en)
[origin: WO03098767A2] The invention concerns a device for protecting (2) an electric power distribution network (1) against transient voltage surges, characterized in that it comprises a discriminating system (4) capable of measuring in the network the voltage variation rate in time and, if the latter is higher than a predetermined value, of electrically connecting said network with at least a conductor component (5) connected to the ground (3). The inventive device provides protection against surge voltages.
