Transmission Line Monitoring System

Transmission lines are an important part of the national power grid. Due to the large span of transmission lines, which usually span hundreds of kilometers, power supply failures are very easy to be affected by various environments.Therefore, it is necessary to regularly monitor the operation status of the transmission line. At present, the manual line inspection method is generally used to achieve this requirement. However, the transmission lines have large horizontal and horizontal span and complicated distribution terrain. There are many kinds of line state parameters, and many links are not easy to be found manually, so the line state cannot be grasped in time.An automatic, accurate and real-time monitoring method is needed to realize the all-weather online monitoring and management of transmission line status.

MW Solution

System requirement

-Meet the needs of long-distance stable transmission.

-Industrial design is adopted to meet the requirements of extreme temperature.

-Isolation protection design for the power supply and ports, which can still work reliably under strong electromagnetic interference.

Maiwe solution


According to the application requirements of transmission line online detection system, Maiweiadopts themethod of 4G/5G communication and accurate monitoring,analysis method to carry out real-time monitoring of transmission line environmental temperature, humidity, wind speed, wire icing,tower tilt and other parameters. It can monitor the status of high-voltage transmission lines and substation insulators operating in harsh atmospheric environments to ensure the safety of transmission lines. The collected values are output through the serial port, and the wireless data transmission terminal transmits these data to the central server through the 4G/5G private network.The central server processes and analyzes the received data, so as to grasp the specific conditions of the transmission lines at each monitoring point, and make corresponding preventive or emergency treatment.
