Solving Electrical Problems with Fluke Thermal Imaging
Today’s thermal imagers have become a realistic solution for everyday electrical maintenance as they are rugged, easy to use, and much more affordable than even just a few years ago. It’s a straight-forward process, where a qualified technician or electrician points the thermal imager at the equipment in question and scans the immediate area, looking for unexpected hot spots. The imager produces a live image of the heat emitted from the equipment and with the quick squeeze of the trigger, a thermal image is captured. When the inspection is complete, the image is uploaded to a computer, Apple®, iPhone® or iPad® for closer analysis, reporting, and future trending.
There are a few basic how-tos to consider… electrical load, safety, and emissivity. In this application note, we walk you through these, as well as the Top 5 Checklist, and much more.

Using Fluke Thermal Imaging to Troubleshoot Motors & Drives
Infrared cameras, also called thermal imagers, are useful for troubleshooting motor problems as well as for monitoring motor condition for preventative maintenance in power generation, manufacturing and commercial plants. Thermal images of motors reveal their operating condition as indicated by surface temperature. Such condition monitoring is important as a way to avert many unexpected motor malfunctions in systems that are critical to manufacturing. The onset of motor failures can often be detected by a variety of techniques, including vibration, ultrasound and thermal imaging.
In this article, we cover why use thermal imaging and what to scan, as well as some notes on what to look for, including shaft misalignment.
