A thermal camera is a really great tool to detect both high and low temperature anomalies. I use to use them to help detect electrical issues due to loose connections or overloaded cables. At one time I had a Level 1 certification and use to train our electricians on how to use the camera as well as setting up a PM program at our plant. Others used these cameras to detect water damage that could not be seen with your eyes but were very evident using the thermal imaging.
About a year or so ago I saw that this technology was being introduced into the PV manufacturing companies to be used during QC evaluation. It does work if you know how to set up the camera for the correct emissivity of what you are scanning.
Thanks for the link russ. -
When they bin these at the factory, they're using a simple current measurement, no? I haven't heard about any discrepancies or complaints with bin rating accuracy. Maybe they're notoriously bad for all I know.Comment
