Transmission lines, distributed across wilderness areas, are prone to damage from natural elements like lightning, pollution, vegetation, wind interference, and icing. These factors often result in tripping accidents, necessitating the prompt and precise identification of fault points and expedited repairs to ensure efficient line operation and maintenance.

This product employs distributed traveling wave measurement technology, with monitoring terminals distributedly installed on transmission line conductors. It collects fault signals(power frequency fault signals and traveling wave fault signals) near the occurrence point and analyzes them at the data center to realize fault interval positioning, precise fault positioning, fault cause identification, and lightning monitoring. Diagnostic results are presented via web and SMS formats.

l Technical indicators

positioning reliability：≥99%

positioning error: ± 1 tower

identification accuracy: ≥ 95%

Power supply: coupling+solar power

l Application

      Applicable to transmission lines of 35kV and above for both AC and DC, with two sets of devices capable of monitoring a 30km line. Widely used in "three-span" lines (crossing high-speed rail, expressways and important passages), localized management lines, DC transmission lines, T-connected lines, and hybrid lines, etc.
