Using LiDAR we achieved route optimization, less remove, 
environment protection, less labor work, process increase quality 
guarantee and created much profit for the client Therefore, we should 
take LiDAR technology to powerline construction.

5 CONCLUSION 
The practice of LiDAR in power grid construction and management 
proved this technology was prior to other means and could be used at the 
whole process of power grid construction and management. Chinese 
power grid’s construction and management ways were out of date. 
Especially after Southern China’s ice disaster of 2008 made the 
construction of digital power grid more important and enhanced the 
construction speed.

4.2 powerline checking 
April, 2007 the most severe storm in fifty years threatened Supervoltage 
Company of North Grid’s 308 kilometers length powerline. The storm 
made lines discharge large parts that affected the electric safety of 
Beijing. The company need to find all the places where the distance 
between lines was close enough to threaten the safety under the situation 
of powerline’s normal operation. So as to install isolation sticks and 
support maintenance. We finished this job by put LiDAR system on a 
helicopter to get the lines’ data. Through LiDAR techonlogy we offered 
precision was 5cm data to the client and help them solve their problem.
