TLKS-PMG-DSCPrecise Fault Location Device for Transmission Lines stands as a core preferred equipment for power industry line operation and maintenance, leveraging four key advantages: high-precision positioning, all-weather real-time monitoring, full-process fault traceability, and intelligent analysis and judgment. Traditional transmission line fault troubleshooting mostly relies on manual line patrols, which has drawbacks such as wide investigation scope, low efficiency, long time consumption, and large positioning errors. After a power outage caused by a fault, it is difficult to quickly locate the point, which easily leads to prolonged power outages and affects power supply reliability. This system breaks through the shortcomings of traditional manual operation and maintenance. Relying on distributed perception and intelligent algorithms, it can provide early warnings for lines, accurately locate fault points, and automatically retain fault data. It adapts to operation and maintenance scenarios of transmission lines in complex terrains, greatly improving the efficiency of power grid fault handling and the intelligent level of operation and maintenance, thus being widely used in power grid operation and maintenance projects at all levels. Its core value is mainly reflected in the following aspects:

Working Principle

TLKS-PMG-DSCPrecise Fault Location Device for Transmission Lines captures various electrical signals such as discharge anomalies and traveling waves during line operation 24 hours a day through distributed monitoring terminals deployed along the transmission line, and initially determines the approximate fault interval. All monitoring data is uploaded to the system master station in real time via wireless network, and simultaneously pushed to the distribution substation and dispatching center. The background relies on intelligent analysis algorithms to conduct in-depth analysis of fault waveforms and operation data, accurately calibrate fault points, distinguish between conventional and sudden faults, and finally output precise reports on fault location and type, guiding operation and maintenance personnel to conduct targeted line patrols and rapid repairs, greatly shortening the fault handling time.

Core Functions

1.Real-time Early Warning: Monitors recessive faults such as weak discharges and abnormal fluctuations of lines around the clock, intelligently judges risk levels combined with historical operation data, and predicts potential faults in advance to achieve pre-control and avoid sudden power outages.

2.High-precision Positioning: Accurately locates potential fault points of lines, with a positioning error controlled within ±300 meters, greatly reducing the manual investigation scope and improving investigation efficiency.

3.Intelligent Fault Location: When sudden faults such as short circuits and ground faults occur on the line, the system can quickly complete fault analysis and precise positioning, output fault information in seconds, solving the problem of traditional blind investigation of the entire line.

4.Complete Fault Waveform Recording: Can completely record the power frequency waveforms and traveling wave waveforms at each point of the line at the moment of the fault, retain complete fault data, and provide reliable data support for fault traceability, cause analysis, and operation and maintenance optimization.

Application Value

TLKS-PMG-DSCPrecise Fault Location Device for Transmission Lines has completely revolutionized the traditional operation and maintenance mode of transmission line faults, realizing the transformation from "passive troubleshooting after faults" to "active early warning before faults and precise handling after faults". On the one hand, it can identify recessive line faults in advance, reducing the probability of line fault power outages from the source; on the other hand, it can quickly locate the point after a fault occurs, greatly shortening the time for line patrols and repairs, and effectively improving power supply stability and reliability. At the same time, complete fault waveform recording data can provide data support for power grid operation and maintenance review, line transformation, and risk assessment, effectively reducing the labor cost of power grid operation and maintenance, and improving the intelligent and refined operation and maintenance level of the power grid.
