PURPOSE:To test respective protective relays between a plurality of electrical stations, with high reliability, by storing respective data in a storage means, and by setting any electrical station on the reference side to change the start point address of the other electrical station so that the data content of the start point address of the storage means may be the same. CONSTITUTION:When in the testing device 6A of an electrical station A on the reference side, a start point address is determined by a CPU6-1A, then its information is transmitted to the testing device 6B of a remote electrical station B, and a data content stored in a storage 6-2B by the address changing means of a CPU6-1B is compared with the data content of a reference point address, and the stored address of the storage 6-2B is changed so that the address of the same content may be the start point address. When start command is issued in such a state, then data are read out of the start addresses of storages 6-2A, 6-2B, and the mimic current and voltage of the same phase are applied to protective relays 1A, 1B. |
