It has been more than 27 years since energizing, the North-South 500kV transmission line circuit 1 is still operating safely, smoothly, bringing electricity to shine everywhere, contributing to socio-economic development.
And one of the prerequisites to make this operation successful is periodic maintenance according to the strict standards of Electricity of Vietnam (EVN).
Today, EVN has applied 3D scanning technology provided by 3D MASTER Co., Ltd. to digitize materials and equipment from small to large, especially 500KVA power poles,... in order to survey and detect quickly the main Determine the current status of actual faults to deploy the most appropriate method of remedial, maintenance and repair.
The 3D scanning devices used belong to the world's most modern and high-speed mobile precision handheld 3D scanning technology, which are: HandyScan Black Elite, origin Creaform, Canada and ZEB Horizon machine, origin GEOSLAM, UK.
