| Zusammenfassung: | In a protective relaying apparatus for an electric power transmission system and the like there is provided a nonvolatile memory device in which various values required for protection of the system are written electrically. An input device designates addresses in the memory device and memorizes values in the addresses under control of a control device. A digital processing device carries out the protective operations for the electric power transmission system based on the values thus set in the non-volatile memory device. |
