Intelligent Monitoring Device for Grounding Resistance of Transmission Lines

Alternative Product Names: Transmission Line Grounding Resistance Monitoring Device, Intelligent Transmission Line Grounding Resistance Monitoring Device, Clamp Meter Method Grounding Resistance Monitoring Device

TLKS-PLGSIntelligent Transmission Line Grounding Resistance Monitoring Device has many core advantages such as online non-destructive testing, high measurement accuracy and efficiency, high safety factor, wide adaptability to scenarios, and intelligent remote monitoring. It is an intelligent dedicated equipment for lightning protection and operation and maintenance of transmission lines. Traditional tower grounding resistance detection relies on manual on-site operations, which not only involves high work intensity and low detection efficiency, but also easily leads to measurement errors due to manual operations, and cannot achieve normalized monitoring, making it difficult to detect hidden defects such as corrosion, aging, and failure of the grounding system in a timely manner. The TLKS-PLGS device abandons the drawbacks of traditional manual detection, does not require power outage or the layout of auxiliary grounding electrodes. Relying on fully automatic online monitoring technology, it can collect grounding resistance data around the clock. Combined with 4G remote transmission and Beidou positioning functions, it realizes accurate grounding investigation and remote control, greatly improves the operation and maintenance efficiency of the transmission line grounding system, effectively avoids lightning trip accidents, and is widely used in power grid transmission operation and maintenance scenarios. Its core value is mainly reflected in the following aspects:

Working Principle

TLKS-PLGSIntelligent Transmission Line Grounding Resistance Monitoring Device realizes accurate monitoring based on the principle of loop resistance detection. Relying on the built-in high-precision sensing module, it actively outputs excitation pulse signals to the tower grounding loop. Through the potential and current parameters generated by the induction loop, combined with the R=E/I calculation formula, it accurately calculates the real-time grounding resistance value. Compared with traditional manual measurement methods, the equipment does not need to contact the tested equipment, does not require power outage or shutdown, and does not need manual layout of auxiliary grounding electrodes. The whole process adopts a non-intrusive online monitoring mode. All data collected by the terminal can be summarized and analyzed in real time, and remotely uploaded to the monitoring center host computer via 4G network. Operation and maintenance personnel can remotely view data, locate points, and conduct investigations, which not only avoids manual operation errors, but also greatly improves the timeliness and accuracy of grounding resistance detection.
