How Linemen find Bad Connections - Thermal Camera

2026-07-18 · 17:46 UTC ·Bobsdecline - Lineman blogger ·1 min read

Brief

Bobsdecline — Lineman blogger (video demo/tutorial) demonstrates using a thermal (FLIR) camera to find a hot, high-resistance connection on an overhead power line. He scans the conductor, points out localized thermal contrast that indicates the fault, and reiterates safety: only trained, authorized utility workers using proper procedures and PPE should perform this work.

Why it matters

Bobsdecline (lineman blogger) uploaded a demo-style tutorial on 2026-07-18 using a thermal/FLIR camera to locate a hot (high-resistance) connection on an overhead power line, showing a localized elevated temperature (a 'hot spot') as the diagnostic signature.

Key details

  • Workflow shown: scan the conductor with a thermal imager, identify thermal contrast/localized heat to pinpoint the bad connection; all work is emphasized as being performed by trained, authorized utility personnel with proper procedures and PPE and explicitly not for DIY.

Hey Everyone!

This is a repost from the early days of the channel.

With so many new subscribers since it was originally uploaded, I figured it deserved another chance.

In this video, I use thermal imaging to identify a hot (high-resistance) connection on an overhead power line and explain what we're looking at.

I'll admit... watching my older videos is a little embarrassing. 😅 I'm not entirely sure why I was yelling at the camera, but we've all got to start somewhere. Hopefully the information is still just as useful today as it was back then.
As always, this work is performed by trained and authorized utility personnel using proper procedures and PPE. Never approach or attempt to work on energized electrical equipment.

Thanks for watching!
