ELECTRIC POWER TRANSMISSION LINE GROUND FAULT AUTOMATIC-LOCATING DEVICE

摘要

An electric power transmission line (6) ground fault automatic-locating device. The electric power transmission line (6) is connected to an outlet side of a substation main transformer (5). Each electric power transmission line (6) is constituted by three phase buses, and each electric power transmission line (6) has arranged thereon several nodes. The locating device comprises: a signal source device (1) connected to a busbar side of the main transformer (5), several fault displays (2) respectively mounted on each phase bus at each node of each electric power transmission line (6), several overhead substations (3) respectively arranged at each node of each electric power transmission line (6), and a central information processing system (4).
