Shaoxing converter-station AI inspection
State Grid reported cutting Shaoxing station inspections from 2 hours to 30 minutes
Problem
Shaoxing converter station contained equipment in hazardous and confined spaces. A complete manual inspection required 2 workers for 2 hours and left some locations difficult to inspect.
Approach
The station entered State Grid's digital converter-station pilot in late 2020. Zhejiang State Grid and Huawei developed an inspection system using drones and ground robots. AI screened visible-light and infrared images, leaving staff to review suspected defects.
Results
Takeaway
Staff retained responsibility for reviewing warnings while machines extended inspection coverage into difficult locations. The reported recognition accuracy did not specify a test sample.
