Smart defense safeguards power supply during summer peak demand

Staff members of State Grid Jiaxing Power Supply Co (State Grid Jiaxing) installed and commissioned two intelligent camera monitoring devices on two 110-kilovolt transmission towers in Haining, Zhejiang province on Aug 11.

The newly added monitoring points further strengthen the company's visualized risk-control system for transmission lines, providing an intelligent safeguard to ensure a stable power supply during the peak summer period.

At the construction site, staff members followed the installation plan and completed equipment mounting, cable connections and camera angle adjustments in sequence. They fine-tuned the cameras' positions and fields of view to ensure clear coverage of the towers, insulator strings, conductor connection points and surrounding passageways.

The monitoring devices are equipped with high-definition cameras and solar power systems, enabling round-the-clock monitoring of transmission lines and their surroundings.

The devices are primarily designed to detect and prevent risks caused by external activities. When large machinery such as tower cranes or excavators enters the safety zone of a transmission line, the system immediately sends an alert to the monitoring platform.

It also monitors floating objects in the line corridor and can promptly notify maintenance personnel when foreign objects such as plastic film or kite strings approach or fall onto the lines.

In addition, the devices periodically capture images of vegetation growth in the line corridor to help prevent insufficient clearance between trees and power lines. They can also remotely monitor the condition of insulators, fittings, conductors and transmission corridors, enabling potential hazards to be identified, flagged and addressed at an early stage.

During the peak summer period, the intelligent cameras can serve as fixed monitoring points, keeping a continuous watch over key sections of transmission lines. This helps address the limitations of manual inspections in adverse weather and ensures transmission corridors remain under effective monitoring and control.

The company is also continuing to promote a coordinated inspection model combining intelligent cameras and drones, with the aim of building an integrated, three-dimensional inspection system that brings together aerial, satellite and ground-based monitoring to strengthen the safety and stability of the power grid.
