Liberty will begin its annual aerial inspection of electric transmission lines and substations this week. This inspection is expected to run Wednesday, August 10, through Friday, August 19; however, the length of the program is dependent upon weather and wind conditions. The helicopter tail number is N724HK.
The aerial inspection process uses a low-flying helicopter to survey approximately 1,300 miles of transmission line throughout Liberty’s local electric service territory. The survey focuses on identifying potential problems with transmission structures, hardware, conductors, and vegetation. The process uses a high-resolution infrared imaging system to detect potential equipment issues that may go undetected in a typical visual inspection.
“Our annual aerial inspection is one of the most efficient ways for us to see our entire system in a short period of time. Doing a routine check-up helps us identify issues that could lead to outages down the road. We can then proactively make needed repairs and help keep electricity safe and reliable for our customers,” said Jason Grossman, Vegetation Control Manager, Liberty.
