If you’ve had Level I Thermographic Applications training course you most likely heard the mantra of “Focus First!” from your instructor, and with good reason! Of all of the camera settings that can be adjusted by the camera operator, focus is by far the most important. Focus is essential to both image quality and temperature [...]
Regardless if you’re inspecting buildings, roofs, or electrical or mechanical apparatus, when you have an abundance of air movement across a surface, there is an increase in heat loss or gain on that surface from convective cooling or heating.
Convective cooling is often discussed in many applications of thermography. Often the result is cooling of anomalous [...]
Whether it’s high rise office buildings, hospitals, or an industrial facility, the approaches to accomplishing an infrared electrical scan vary as much as the locations. One universal thread throughout these inspections is the manner in which most electrical maintenance folks expose panels for inspection.
Most industrial grade panels have a two part cover but these configurations [...]
Roof moisture inspections are one of those applications of infrared thermography that many in the industry have heard of, but not so many have attempted. It’s kind of a niche application, really. In my decade or so of experience in this industry, I’ve only had the opportunity to be involved in a handful of these [...]
Let’s face the facts: we are seen as experts. Customers expect answers from us, usually immediate answers. How tempting it can be to make them happy! Armed with our expensive, high-tech tools, it is all too easy to forget we can’t always come up with those answers.
The temperature difference on this failing surge protection [...]
I’ve been working on a project this past week with a couple of young people. I’m impressed with two things. First, they have more energy than I have. Second, I have more experience than they have. While energy is great, relying on experience often means I know how to do things “smarter,” using less energy. [...]
Some problems don’t necessarily “shout” at you. The increase in temperature of this surge protection device in a substation is only a few degrees warmer than normal. Seeing the signature required adjusting the imager skillfully. Understanding the device could fail at any moment required additional background knowledge and clear [...]
Last week I talked about the value of following professional standards. Not only do they lay out the best “recipe” for success but standards are also widely accepted as “collateral” in most industries where we work. By following standards, your work will immediately gain credibility.
Section 14 of ASTM C-1153, Standard Practice for Location of [...]
Last week I talked about how to move yourself and your imager into the best position to get good thermal data. Another big part of being successful is understanding and following professional thermography standards. Like a good time-tested recipe, these help us get high quality, consistent results.
As I’ve said before, I’ve made plenty of mistakes [...]
The image palettes we have available to us are remarkable. They’ve come so far since I first got into this business in 1983. We can now also easily change the palette in the software. Wow!
The Fluke AMBER palette with red and blue saturation indicators is a nearly perfect palette to use, especially in the [...]
