要約(英語): Tokyo Electric Power Company (TEPCO) introduced the Lightning Position And Tracking System (LPATS) Version III in 1990. The system uses the time-of-arrival technique for lightning location. TEPCO had studied the operating characteristics of the system, and had confirmed its effectiveness. However, further improvement of the functions and performance was necessary from the viewpoint of utilities. TEPCO, therefore, began development of the LPATS-T (version TEPCO) in cooperation with Global Atmospherics, Inc. and formally put the system into operation in 1996. Performance of LPATS-T at TEPCO was evaluated based on comparison with actual lightning current measurement data at transmission towers. Forty negative first return strokes observed at instrumented transmission towers were detected by LPATS-T from 1996 to 1999. Location error was estimated to be about 600m on average. Estimated peak currents were compared with directly measured values.
