How IoT Empowers Transmission Line Monitoring

In this article, we’re going to share with you cases of how IoT helps to empower the transmission line monitoring for power utility.


With the development of society, Mechanization, life electrification, people’s electricity consumption is increasing every year.

The transmission lines are an important part of the National Power Grid. However, due to the transmission lines usually spans hundreds of kilometers, they are very susceptible to various environmental factors and causes power failures.

In this instance, it is necessary to monitor the operation status of transmission lines on a regular basis. However, there are many disadvantages and inconvenience in the conventional manual inspection of transmission lines. For example, transmission lines have large span and complicated topography, and too many parameters of line state, ect, which are not easy to discover manually, nor grasp the state of the line in time. Therefore, an automatic, accurate, real-time monitoring mode is requested to realize monitoring and management of transmission line status day and night.

System Composition

The system mainly adopts wireless 4G/3G/GSM/GPRS to monitor the environmental temperature, humidity, wind speed, ice covering, transmission line temperature, galloping, the inclination of the tower, etc., in order to ensure the safety of transmission line.

The entire system are mainly including following components.

  1. Air Temperature and Humidity Sensor
  2. Vibrates Sensor
  3. Wind speed and direction sensor
  4. Water Covering Controller
  5. Transmission line temperature sensor
  6. Bivocom industrial 4G/3G/2G DTU or router
  7. Remote data server center or cloud for scheduling and analysis; Mainly responsible for the analysis and management of the original data, and system analysis results display, processing.
