Industry solutions
Transmission line status perception system
Long-distance transmission lines are usually exposed to complex and changeable natural environments, and are prone to voltage fluctuations, line short circuits or aging. Long-distance transmission lines are prone to voltage instability, short circuits or equipment aging in harsh environments. The traditional manual inspection is inefficient and requires a more complete transmission line status perception system with excellent electrical sensors.
- Recommended Sensors
| Recommended sensor | Recommended reason |
| Voltage sensor | Detects whether the line voltage is within a safe fluctuation range and identifies voltage drops or spikes. |
| Magnetic sensor | Used to determine whether the wire has abnormal magnetic field changes such as external force vibration, fault pulling, etc. |
| Signal isolator | Electrically isolates the remote node signal, enhances anti-interference ability, and improves data communication stability. |
- Solution Recommendation
Deploy voltage sensors at key transmission nodes to monitor the voltage of the trunk line to ensure that the power supply fluctuation is within a safe range. At the same time, install magnetic sensors at the connection between the tower and the wire to monitor the magnetic disturbance caused by wind pressure, vibration or foreign object collision. With the signal isolator, various sensor data are stably transmitted to the remote monitoring platform to realize the transmission line status perception system.
