QJ13 Micro-Meteorological Monitoring Instrument records transmission and distribution grid environmental information 24 hours without failure.

In recent years, with the rapid development of China's power industry, the safe and stable operation of transmission lines has received increasing attention. Meteorological conditions, as one of the critical factors affecting the safety of transmission lines, make their monitoring and early warning particularly important. As a specialized meteorological monitoring device, micro-meteorological monitors are playing an increasingly vital role in transmission line applications.

Dongguan Lvguang's 【QJ13】 micro-meteorological monitor can monitor meteorological parameters along transmission lines in real-time, providing a scientific basis for line operation and maintenance. Transmission lines often traverse complex geographical environments with significant variations in climatic conditions along their routes. By deploying micro-meteorological monitors, real-time data on temperature, humidity, wind speed, wind direction, precipitation, and air pressure can be obtained. This data is crucial for assessing line operating conditions and predicting potential risks. For example, during hot weather, conductors expand due to heat, increasing sag and potentially causing ground discharge accidents. Using temperature data from micro-meteorological monitors, maintenance personnel can promptly adjust line operating parameters to prevent such incidents.

In dealing with extreme weather, the role of micro-meteorological monitors is particularly prominent. Extreme weather events such as typhoons, hail, and heavy rain pose serious threats to transmission lines. In April 2025, a regional power grid experienced multiple line trips due to sudden severe convective weather. With real-time data from micro-meteorological monitors, the dispatch center can predict weather trends in advance and activate emergency plans promptly. For instance, when wind speeds exceed design thresholds, reinforcement measures or operational adjustments can be implemented early to minimize losses. Additionally, micro-meteorological monitors provide valuable references for line design. When constructing new lines, historical data from these monitors helps accurately determine key parameters like design wind speed and ice thickness, enhancing the line's disaster resilience.

Advancements in meteorological monitoring technology provide stronger support for the safe operation of transmission lines. Modern micro-meteorological monitors commonly use IoT technology for remote data transmission and centralized processing. Some advanced models are also equipped with video surveillance devices to visually observe weather conditions around the lines. The application of artificial intelligence makes meteorological data analysis more intelligent. Through deep learning of historical data, systems can more accurately predict short-term weather changes, supporting maintenance decisions. For example, a smart early warning system developed by a grid company, combining micro-meteorological monitor data and line parameters, can predict ice accretion risks 72 hours in advance, guiding de-icing operations.

Micro-meteorological monitors also play a key role in lightning protection for transmission lines. Lightning is a major cause of line trips. Data on lightning activity collected by these monitors can be used to create lightning density maps, informing lightning protection design. During thunderstorm seasons, real-time lightning monitoring helps maintenance personnel quickly locate fault points, reducing repair time. Some micro-meteorological monitors are equipped with atmospheric electric field sensors to monitor changes in local electrostatic field strength, providing early warnings of potential lightning strikes.

In ice monitoring, micro-meteorological monitors are equally indispensable. Low-temperature rain and snow in winter can lead to ice accretion on lines, which may cause tower collapses and wire breaks in severe cases. By monitoring parameters such as temperature, humidity, and precipitation type, and combined with specialized ice monitoring devices, micro-meteorological monitors can accurately assess ice risk. When conditions conducive to ice formation are detected, the system automatically issues warnings, prompting de-icing measures. For instance, using data from micro-meteorological monitors, a high-altitude line successfully predicted a severe ice accretion process in late 2024 and activated DC de-icing devices in time, avoiding significant losses.

Long-term accumulation of meteorological data also provides valuable references for the planning and construction of transmission lines. By analyzing multi-year meteorological data, climate characteristics along the lines can be understood, optimizing route selection. During micro-siting, meteorological data helps determine precise tower locations, avoiding unfavorable areas like wind tunnels and ice-prone zones. Furthermore, meteorological data is used to assess the environmental adaptability of lines, guiding the selection of appropriate hardware and insulation materials.

In the future, with technological advancements, the application of micro-meteorological monitors in transmission lines will become more extensive and in-depth. The adoption of 5G communication technology will enhance the real-time performance and reliability of data transmission. The integration of satellite remote sensing with ground-based micro-meteorological monitors will enable broader weather monitoring. The application of digital twin technology will allow meteorological data to deeply integrate with 3D line models, enabling more precise simulation analysis. It is foreseeable that intelligent meteorological monitoring systems will become an indispensable part of ensuring grid security.

Overall, as the "meteorological sentinel" of transmission lines, micro-meteorological monitors play multiple roles in real-time monitoring, disaster warning, and operational optimization. With the power system's increasing demands for safety and reliability, meteorological monitoring technology will continue to innovate, providing stronger support for the stable operation of the grid. Power companies should prioritize the construction and improvement of meteorological monitoring systems, fully leverage the value of meteorological data, and continuously enhance the disaster resilience and maintenance levels of transmission lines.
