State Grid Corporation of China was established on December 29, 2002. It is a super-large state-owned backbone enterprise that plays a vital role in the national economy and energy security, undertaking essential infrastructure construction tasks. As the number of substations increases, the safety risks and cost pressures associated with manual inspections have also escalated. With the development of digital technology, replacing manual inspections with intelligent inspections has become an inevitable trend and a crucial choice for ensuring the safe operation of substations and the power grid.
