The JW-IWS-EG(LC34) Transmission Line Weather Monitoring System is an integrated microclimate, severe-weather recognition and remote early-warning solution developed for overhead transmission lines, power towers, substations and high-risk grid corridors.
The system continuously monitors local environmental conditions around transmission infrastructure, providing field data that regional weather forecasts may not accurately represent.
Depending on the project configuration, it can measure:
Air temperature
Relative humidity
Dew point
Wind speed
Wind direction
Atmospheric pressure
Rainfall
Solar radiation
Illuminance
UV radiation
Noise
PM1.0
PM2.5
PM10
Visibility
Local weather phenomena
The system can also support visual weather recognition for conditions such as sunshine, rain, snow, fog, haze, thunderstorm, hail, frost, dew and sandstorm.
With remote communication, cloud visualization and threshold alarms, it helps power utilities improve transmission-line inspection, strong-wind warning, icing-risk assessment, tower-foundation protection and preventive maintenance.
What Is a Transmission Line Weather Monitoring System?
A transmission line weather monitoring system is a field monitoring station installed near overhead conductors, transmission towers, tower foundations or critical sections of a power corridor.
Its purpose is to collect local meteorological and environmental data that may affect power-line safety.
Transmission lines often cross:
Mountains
Valleys
Rivers
Forests
Coastal areas
High-altitude regions
Icing-prone areas
Typhoon corridors
Landslide-prone slopes
Remote regions with limited access
Weather conditions in these locations may differ significantly from data collected by a distant public weather station.
Local monitoring therefore gives grid operators more representative information for operation, inspection and risk assessment.
Regional weather forecasts describe a wider area, but transmission-line risks are often highly localized.
A mountain saddle may experience stronger wind than a nearby town. A shaded high-altitude section may develop icing while lower line sections remain unaffected. Heavy rainfall may destabilize only one tower foundation or slope.
A field monitoring point can provide data directly from the affected corridor.
This supports:
More accurate strong-wind assessment
Faster identification of icing-prone conditions
Better inspection scheduling
Early detection of extreme weather
More targeted emergency response
Reduced unnecessary field visits
Historical comparison between weather and line events
Weather-Related Risks Monitored
Strong Wind and Conductor Galloping
Strong wind, crosswind and turbulent airflow may contribute to:
Conductor galloping
Wind-induced vibration
Wind deviation
Reduced electrical clearance
Tower and fitting stress
Damage to insulators or hardware
Increased risk at cross-valley and cross-river sections
Wind speed alone does not fully determine conductor behaviour, but continuous wind data provides important context for line-risk assessment.
Recommended parameters include:
Wind speed
Wind direction
Gust conditions
Air temperature
Precipitation
Video observation
Optional tower tilt or vibration
Icing and Freezing Conditions
Conductor icing can increase mechanical load and affect line safety.
Weather conditions associated with icing may include:
Low temperature
High humidity
Freezing rain
Fog
Supercooled water droplets
Low wind or changing wind
Frost and dew-point conditions
The system can provide the meteorological inputs required for icing-tendency analysis.
For projects requiring direct icing thickness or conductor-load measurement, additional dedicated sensors may be required.
Heavy Rainfall and Tower-Foundation Risk
Long-duration or intense rainfall can affect:
Tower-foundation erosion
Slope stability
Surface runoff
Landslide risk
Flash-flood risk
Access-road conditions
Drainage around tower bases
Rainfall monitoring can be combined with:
Soil moisture
Groundwater level
Slope displacement
Tilt
Crack monitoring
Cameras
Water-level sensors
Fog, Haze and Low Visibility
Fog, haze, snow and heavy rainfall can reduce visibility and affect:
Manual inspection
Drone inspection
Helicopter inspection
Emergency access
Camera image quality
Maintenance safety
Optional visibility monitoring and image recognition provide additional information for field operations.
High Temperature and Fire Risk
High temperature, low humidity and strong wind may increase vegetation and wildfire risk along some transmission corridors.
The system may be expanded with:
Smoke detection
Fire-weather parameters
Video monitoring
Thermal imaging
Soil moisture
Vegetation monitoring
Local alarm devices
Coastal and Salt-Fog Environments
Coastal transmission lines may face:
Strong wind
Typhoons
High humidity
Salt spray
Corrosion
Sudden rainfall
Electrical-insulation contamination
Equipment materials, connectors, mounting structures and communication enclosures should be selected for the local corrosion environment.
Parameters Monitored
Air Temperature
Temperature data supports:
Icing-risk analysis
Thermal operating assessment

Environmental trend monitoring
Relative Humidity and Dew Point
Humidity and dew point help assess:

Insulator surface conditions
Local atmospheric moisture
Wind Speed and Wind Direction
Wind data is critical for evaluating:
Crosswind conditions
Gust events
Corridor airflow
Conductor galloping risk
Wind deviation
Tower exposure
Typhoon impact
A high-precision ultrasonic wind sensor can be selected for projects requiring no moving parts and reduced maintenance.
Noise monitoring may support selected projects involving:
Corona-related environmental studies
Nearby construction activity
Industrial-zone monitoring
General environmental networks
It should not be treated as a direct substitute for specialized electrical-discharge diagnostic equipment.
Recognizable Weather Conditions
Depending on the camera, recognition algorithm and selected configuration, the system can support identification of:
Sunny conditions
Rain
Snow
Fog
Haze
Thunderstorm conditions
Hail
Frost
Dew
Sandstorm
Cloud cover
Reduced visibility
Image recognition should be used together with measured sensor data rather than as the only source for critical alarms.
