  • Method for protecting at least a part of a network segment of an electrical power distribution network
    Patent number: 11955792
    Abstract: A method for protecting at least a part of a network segment of an electrical power distribution network has: detecting voltage dips at the intermediate feeding devices of the line arrangements by the voltage dip detection devices; generating and feeding an electrical signal into the line arrangement by the signal generating device at each intermediate feeding device at which one of the voltage dips is detected, the electrical signals having frequencies different from a network frequency of the network segment; receiving the electrical signals via the line arrangements by the receiving devices of the line protection devices; detecting electrical faults on the line arrangement using the electrical signals received by the triggering device of the respective line protection device; and triggering the disconnecting device of the line protection device of the line arrangement, where an electric fault is detected, by the triggering device so that the line arrangement is electrically disconnected from the further el
