为什么在输电塔底部安装水浸传感器对智能电网安全至关重要？

As the power grid advances toward higher levels of intelligence and automation, its overall reliability increasingly relies on the stability of physical assets such as transmission towers. Although cutting-edge technologies like drones, IoT sensors, and AI analytics have greatly improved grid operation and maintenance, one often-overlooked factor continues to pose a serious threat — water accumulation at the tower base. Prolonged exposure to moisture weakens the surrounding soil, leads to uneven settlement, and can ultimately cause Transmission Tower Tilt or even collapse. To address this hidden but critical risk, installing Water Immersion Sensors at tower foundations has become an essential part of Tower Health Monitoring and Smart Grid Safety strategies. By continuously detecting water levels and integrating with advanced technology or solutions such as TruGem 杆塔倾斜监控 解决方案通过该系统，电力公司可以对电网基础设施进行主动、数据驱动的管理，确保长期稳定性和运营智能化。

防止铁塔倾斜和倒塌：保护电网骨干网

隐藏的风险

输电塔在恶劣的户外环境中运行--经受风雨和土壤移动的考验。当塔基长时间浸泡在水中时，周围的土壤会变软，从而大大降低其摩擦力和承重能力。

后果

Once the foundation weakens, even moderate external forces like wind or uneven terrain pressure can lead to Transmission Tower Tilt or, in severe cases, total collapse. For high-voltage or ultra-high-voltage lines, such accidents can cause massive outages, economic losses, and even pose safety hazards to nearby communities.

解决方案

By installing Water Immersion Sensors near the tower base, operators gain real-time visibility into soil moisture and water levels. The system sends immediate alerts when water accumulation exceeds safe thresholds, allowing maintenance teams to act before structural instability develops.

This early-warning capability shifts maintenance from reactive repair to proactive prevention — a cornerstone of modern Tower Health Monitoring.

在寒冷地区预防冻害

隐藏的风险

In northern or high-altitude regions, another threat emerges — frost heave. When moisture-laden soil freezes in winter, the expanding ice pushes the foundation upward. During spring thaw, the ground settles unevenly, leading to repeated up-and-down movement known as freeze-thaw cycles.

后果

These seasonal fluctuations can cause Transmission Tower Tilt, micro-cracks in concrete foundations, and stress fractures in metal joints. Over time, the structural integrity of the entire tower may degrade, leading to expensive repairs or replacements.

解决方案

By using Water Immersion Sensors, utilities can monitor soil moisture in the fall and receive early warnings before the ground freezes. This enables timely drainage or insulation measures to prevent frost heave and ensure the foundation remains stable throughout the winter.

This data-driven preventive maintenance enhances both Smart Grid Safety and asset longevity.

洪水和自然灾害预警

隐藏的风险

输电塔通常建在不同的地形上--河岸、山坡或空旷的田野--它们面临着洪水、暴雨和山洪暴发的威胁。

后果

严重的积水会侵蚀土壤，暴露地基，甚至冲走保护层。洪水期间，控制柜或接地设备可能会被淹没，造成运行和安全隐患。

解决方案

A Water Immersion Sensor acts as a front-line “sentinel” during natural disasters. Integrated with real-time communication systems, it provides live data on water levels around each tower. This enables control centers to make informed decisions — such as rerouting power loads or dispatching field teams in advance — before damage occurs.

In combination with Tower Tilt Monitoring, operators can evaluate both horizontal displacement and vertical stability, building a comprehensive early warning system for extreme weather events.

从人工检测到智能维护

传统挑战

一直以来，输电塔检测都是依靠人工每隔几周或几个月进行一次实地考察。然而，这种方法有几个缺点：

• 较长的检查间隔意味着洪水或侵蚀等问题可能几周都不会被发现。
• 偏远地区或山区交通不便，成本高昂。
• 人工检查存在安全风险，尤其是在恶劣天气下。

智能转型

By deploying IoT-enabled Water Immersion Sensors, operators can achieve 24/7 automatic monitoring with minimal human intervention. Each sensor continuously transmits real-time data to a central monitoring platform.

当检测到异常读数时，系统会自动识别塔的确切位置，并向维护人员发送警报。这样，团队就可以只关注有问题的地点，从而大大提高效率、降低成本，并最大限度地减少现场暴露。

结果

This transformation from scheduled maintenance to condition-based maintenance represents a major leap toward intelligent grid operation and aligns perfectly with the principles of Tower Health Monitoring.

保护塔基和金属构件

隐藏的风险

Continuous exposure to moisture accelerates concrete carbonation and corrosion of metal parts like anchor bolts, tower legs, and grounding plates.

后果

腐蚀不仅会削弱物理结构，还会破坏接地性能，增加雷击损坏或电气故障的风险。随着时间的推移，这些问题会缩短铁塔的使用寿命，增加维护成本。

解决方案

By providing early warnings of prolonged water exposure, Water Immersion Sensors enable quick drainage and mitigation actions. Maintaining a dry foundation environment helps preserve both structural integrity and electrical performance — extending asset life and ensuring long-term Smart Grid Safety.

基于北斗/GPS 的塔架倾斜监测和水浸感应解决方案

While water immersion sensors detect potential softening and erosion of the foundation, GPS/Beidou Satellite monitor structural tilt or displacement and angular deformation. When these two technologies are integrated, they form a comprehensive Tower Health Monitoring solution.

TruGem’s Beidou/GNSS-based Tower Tilt Monitoring Solution combines high-precision RTK (Real-Time Kinematic) positioning with real-time Water Immersion Sensor data to deliver a full picture of tower stability:

• 北斗 RTK 精度: Provides centimeter-level accuracy for continuous Transmission Tower Tilt monitoring.
• 物联网连接:通过 4G 或 Lora 网络传输实时水位和倾斜数据。
• 多级警报:支持短信、应用程序和控制中心通知，以便快速做出决策。

这些技术结合在一起，使电网运营商能够从被动维护转变为预测性智能，确保电网安全和在所有环境条件下的连续运行。

结论

Installing Water Immersion Sensors at the base of transmission towers is far more than a technical upgrade — it’s a strategic step toward building a resilient, intelligent, and sustainable power grid.

By preventing water-induced foundation failures, detecting Transmission Tower Tilt, and enabling real-time Tower Health Monitoring, these sensors protect both infrastructure and public safety. When integrated with Beidou/GPS-based Tower Tilt Monitoring Solution, they form a powerful solution that enhances Smart Grid Safety, improves operational efficiency, and supports the global shift toward digital power management.
