WS-EG(LC34) Transmission Line Weather Monitoring System is an integrated microclimate monitoring solution designed for high-voltage transmission lines, power towers, substations, and remote power grid infrastructure.
By combining meteorological sensors, optional weather-phenomenon recognition, data acquisition, and wireless communication, the system provides localized environmental measurements to support grid operation, severe-weather assessment, and preventive maintenance.
Unlike regional weather forecasts, field monitoring stations collect weather data directly from transmission corridors where wind, rainfall, temperature, and freezing conditions may vary significantly between locations.
1. Why Transmission Lines Need Local Weather Monitoring
Overhead power lines frequently cross mountains, valleys, forests, rivers, coastal zones, and remote areas.
These environments create localized weather conditions that regional forecasts may not fully represent.
A transmission line weather monitoring system helps operators observe weather-related risks at critical locations.
Typical applications include:
Strong-wind monitoring near exposed towers.
Icing-risk observation along high-altitude transmission corridors.
Rainfall monitoring near tower foundations.
Fog and visibility assessment for field inspection.
Environmental monitoring around remote substations.
The system provides supporting data for operational decisions; it does not directly replace specialized conductor-condition, structural-load, or electrical fault monitoring equipment.

Optional Environmental Monitoring
Depending on system configuration, additional monitoring may include:
Atmospheric pressure
Visibility
Weather-phenomenon recognition
Camera observation
Soil moisture
Tower tilt and displacement monitoring through additional devices
3. Transmission Line Strong-Wind Monitoring
Wind Speed and Direction
Strong wind, crosswind, and turbulent airflow can affect overhead conductors and transmission towers.
Continuous wind monitoring provides useful information about:
Wind speed and gust conditions.
Dominant wind direction.
Crosswind exposure.
Weather conditions associated with conductor movement.
Extreme wind events along valleys and mountain passes.
Wind measurements can support conductor-galloping risk assessment, but wind data alone cannot determine actual conductor displacement or mechanical loading.
Conductor icing can increase mechanical loading and create operational risks for overhead transmission lines.
Icing-prone environments often involve combinations of:
Low air temperature.
High relative humidity.
Freezing precipitation.
Fog or cloud exposure.
Changing wind conditions.
The JW-IWS-EG(LC34) provides meteorological observations that can support icing-tendency analysis and weather-related warning systems.
For projects requiring direct ice-thickness, conductor-temperature, or mechanical-load measurements, additional dedicated monitoring instruments are necessary.
Optional Weather-Phenomenon Recognition
The system can be configured to recognize weather conditions such as rain, snow, hail, fog, haze, frost, dew, and sandstorms.
Recognition capability depends on the selected equipment and algorithm configuration and should complement direct sensor measurements.
5. Heavy Rainfall and Tower-Foundation Monitoring
Heavy rainfall and prolonged wet conditions can contribute to slope instability, soil erosion, surface runoff, and access-road deterioration near transmission infrastructure.
Rainfall monitoring provides useful information for:
Identifying heavy-rainfall periods.
Analyzing accumulated precipitation.
Planning tower-foundation inspections.
Assessing site conditions after storms.
Projects involving unstable slopes may integrate additional groundwater, soil moisture, tilt, or displacement sensors.
6. System Architecture and Remote Data Transmission
The JW-IWS-EG(LC34) can be deployed as an independent monitoring station or integrated into a distributed power grid monitoring network.
Typical System Architecture
Weather Sensors / Optional Camera → Data Logger / RTU → Wireless Communication → Cloud or Utility Platform → Monitoring Dashboard and Alerts
Field Monitoring Layer
Meteorological sensors collect local weather measurements from selected locations along the transmission corridor.
Data Acquisition Layer
Compatible terminals acquire data through interfaces such as RS485 Modbus, analog signals, pulse inputs, or digital inputs, depending on equipment selection.
Communication Layer
Available configurations may include:
4G LTE: For distributed towers with cellular coverage.
LoRaWAN: For multiple low-data-volume monitoring points connected through suitable gateways.
NB-IoT: For supported low-power communication applications.
Ethernet: For substations and other sites with wired infrastructure.
Monitoring Platform
Depending on configuration, the platform can provide:
Remote transmission lines may have limited access to grid power or communication infrastructure.
Solar-powered monitoring configurations can support unattended weather observation.
A typical system may include a solar panel, charge controller, battery, data acquisition terminal, and selected meteorological sensors.
Power capacity should be calculated according to sensor consumption, communication frequency, winter solar availability, equipment heating requirements, and battery autonomy.
8. Applications for Different Power Grid Environments
Mountain Transmission Corridors
Monitor localized wind, temperature, humidity, and rainfall around exposed towers, mountain saddles, and high-altitude sections.
Icing-Prone Power Lines
Collect meteorological data relevant to freezing, fog, and precipitation conditions to support icing-risk assessment.
Cross-Valley and Cross-River Transmission Lines
Measure local wind speed and direction near long spans and exposed crossing locations.
Coastal and Typhoon-Prone Areas
Monitor strong winds, heavy rainfall, humidity, and other relevant weather conditions. Equipment corrosion protection must be selected according to the site environment.
Remote Substations
Provide local weather monitoring with data integration into compatible utility management platforms.
9. Installation Recommendations
Monitoring accuracy depends on sensor placement and installation quality.
Key recommendations include:
Select locations according to wind exposure, icing history, terrain, and operational risk.
Avoid installing wind sensors in heavily obstructed airflow.
Use appropriate radiation shielding for air temperature and humidity sensors.
Install and level rainfall sensors according to their manuals.
Protect communication cables, connectors, and power enclosures from outdoor exposure.
Evaluate lightning protection, grounding, electrical clearances, and tower-access requirements.
Confirm cellular coverage or wireless gateway connectivity before deployment.
Installation on or near energized power infrastructure must follow applicable utility safety rules and be performed by authorized personnel.
