TLKS-PLGS Solar-powered Grounding Resistance Monitor is designed in accordance with the State Grid Q/GDW1242 - 2015 specification, tailored for overhead transmission line towers and substation grounding grids. It adopts the three-pole measurement principle, automatically measures grounding resistance once every 24 hours by default, and the data is remotely uploaded to the monitoring platform via 4G network, supporting real-time viewing through mobile APP and web terminal. The device uses a "solar + lithium battery" self-powered system, with a backup duration of no less than 30 days in rainy and cloudy weather, and is easy to install and operate, suitable for outdoor overhead line tower grounding scenarios. Its core mission is to monitor grounding resistance in real time and prevent lightning-induced tripping accidents caused by excessive resistance.

I. Three "Pain Points" of Traditional Detection

In the past, grounding resistance detection relied entirely on manual work: climbing heights, pulling wires, and laying auxiliary electrodes, with a cumbersome process and low efficiency, and only quarterly or annual sampling inspections were conducted. Often, the grounding resistance would deteriorate quietly between two inspections—by the next measurement, the tower might already be in a "high lightning risk" state. The emergence of the TLKS-PLGS Solar-powered Grounding Resistance Monitor has completely changed this passive situation: it does not require power outage, does not depend on manual electrode laying, operates around the clock, and completes an accurate measurement automatically every 24 hours (adjustable), with real-time data return, turning grounding resistance from an "invisible variable" into a "traceable constant".

II. Working Principle: Small Signal Injection to Accurately Calculate R Value

The measurement logic of the device is clear and reliable: an excitation current with an amplitude of only 11mA is injected into the grounding loop, while the generated potential E is measured, and then the grounding resistance value is calculated in real time according to Ohm's law R=E/I. The whole process has zero interference to the operating equipment and is not affected by on-site electromagnetic noise, with stable and repeatable measurement results. It fully meets the requirements of Q/GDW1242-2015 specification and provides real and effective data support for the reliability evaluation of lightning protection grounding systems.

III.Five Practical Features

1.Quick Measurement: No need to set auxiliary electrodes, no need to climb heights or pull wires, ready to use after installation, greatly reducing detection man-hours.

2.High Safety Guarantee: No electrical contact between the measurement process and the measured object, effectively eliminating the risk of electric shock for operators.

3.Strong Environmental Adaptability: Can be deployed in complex grounding scenarios such as high-voltage towers, strong-interference substations, and mountainous areas.

4.Real-time Dynamic Tracking: Automatically measure and record the change curve of grounding resistance according to the set cycle, making abnormal data easy to identify at a glance.

5.Non-intrusive Operation: No line power interruption during measurement, zero impact on the power system, suitable for high-reliability power supply sections.

V. Intelligent Early Warning + Linkage Response: Nipping Lightning Risks in the Bud

When the TLKS-PLGS Solar-powered Grounding Resistance Monitor detects abnormal fluctuations in grounding resistance data (such as continuous rise or sudden drop), it will immediately trigger the intelligent early warning mechanism and push the alarm information to the mobile APP and web platform via 4G network. It can be understood as a keen "grounding sentinel"—sending an alarm at the first time and automatically marking the Beidou position of the faulty tower, allowing operation and maintenance personnel to locate quickly and deal with timely, effectively reducing the probability of lightning-induced tripping caused by excessive grounding resistance.

VI. Conclusion: Upgrading Grounding Safety from "Regular Sampling Inspection" to "All-weather Monitoring"

Today, as the requirements for lightning protection reliability of transmission lines continue to increase, the TLKS-PLGS Solar-powered Grounding Resistance Monitor, with its four core advantages of standardized design, accurate measurement, remote transmission, and ultra-long standby, has built an all-weather defense line for the grounding system of each tower and each substation. It no longer relies on manual periodic sampling inspections, but allows grounding resistance to "speak for itself and take the initiative to alarm". Choosing it is to select a 24-hour on-duty "grounding safety butler" for the power system.
