Smart inspections make grid more stable

In the prefecture-level city of Xiangyang in Hubei province, power technician Zhang Feiran sat in her office on May 1, gazing at the computer screen and pressing the execution button of a drone intelligent-inspection system.

At the 220 kilovolt Dongjin power substation a few kilometers away, a drone nesting inside the substation slowly took off, starting its remote intelligent inspection of the No 2 main transformer.

When the drone's AI intelligent inspection and diagnosis data showed the transformer was running normally, Zhang — from the substation operation and maintenance branch of State Grid Xiangyang Power Supply Co — was quite relieved.
