METHOD AND APPARATUS FOR RETRIEVAL OF TRANSMISSION LINE END

摘要

PROBLEM TO BE SOLVED: To look for a corresponding transmission side end securely among a plurality of transmission side end candidates on a receiving side and improve the power wiring construction work efficiency when the transmission side ends are not clear in a power switchboard, etc. SOLUTION: The main apparatus M of a sequence control means which repeats a continuity check with a time interval of one second and with a check cycle period of 60 seconds and which has a plurality of terminals are connected to transmission side ends 1-59. Continuity check signals which are successively transmitted to receiving side ends from the transmission side ends are received by a continuity checker CH and the lapses of times from the start of the whole continuity check signal transmission whose period is 60 seconds are measured to look for the transmission side end corresponding to the receiving side end among a plurality of the transmission side end candidates.
