TLKS-PMG-DSCPrecise Fault Location Device for Transmission Lines relies on four core advantages—high-precision positioning, all-weather real-time monitoring, full-process fault tracing, and intelligent analysis and judgment—to become a core preferred equipment for line operation and maintenance in the power industry. Traditional transmission line fault detection mostly relies on manual line patrol, which has drawbacks such as wide detection range, low efficiency, long time consumption, and large positioning error. After a power outage due to a fault, it is difficult to quickly locate the point, which easily causes a long-term power outage 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 early warn of line faults, accurately locate fault points, and automatically retain fault data. It is suitable for 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, so it is 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 fault 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 back end relies on intelligent analysis algorithms to deeply analyze fault waveforms and operation data, accurately calibrate fault points, distinguish between conventional and sudden faults, and finally output accurate fault location and fault type reports, 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: Monitor hidden faults such as weak discharge and abnormal fluctuations of lines around the clock, intelligently judge the risk level combined with historical operation data, and predict potential faults in advance to achieve pre-control and avoid sudden power outages.

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

3.Intelligent fault location: When a sudden fault such as a short circuit or ground fault occurs on the line, the system can quickly complete fault analysis and precise positioning, output fault information in seconds, solving the problem of traditional blind inspection of the entire line.

4.Complete fault 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 tracing, cause analysis, and operation and maintenance optimization.

Application Value

TLKS-PMG-DSCPrecise Fault Location Device for Transmission Lines has completely innovated the traditional transmission line fault operation and maintenance mode, realizing the transformation from "passive fault investigation after failure" to "active early warning before failure and precise handling after failure". On the one hand, it can identify line hidden 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 patrol and repair, and effectively improving power supply stability and reliability. At the same time, complete fault 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.
