The discovery that accurate temperature measurements are many times difficult in electrical applications of thermography can be a hard pill to swallow. Electrical apparatus are often made from metal that’s bare, so emissivity is low, and thus temperature measurements are unreliable.
The good news is that despite this fact, electrical anomalies can be relatively easy to [...]
One of the easiest, and often safest, types of electrical apparatus to inspect are oil-filled transformer cooling [...]
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 [...]
There’s a lot written about electrical safety as it applies to infrared inspections. The danger of electric shock and exposure to arc flash hazards must be considered when inspecting electrical apparatus with thermography. What isn’t discussed nearly as often are the hazards associated with mechanical infrared inspections, of which there are many.
The punch line to the old joke, “How do you get to Carnegie Hall?” is three simple words, “Practice, practice, practice.” The same would hold true if there was a thermographic equivalent to Carnegie Hall. You’d get there with practice … lots of it!
Some folks who come to Level I infrared training, however, express that [...]
We have several customers that we visit and perform infrared scans for on a regular basis. Recently we were in a textile mill in a state where we’ve been performing inspecting for the past four years. The equipment list has remained virtually unchanged in the time we’ve been inspecting there. The only variances were during shutdowns for [...]
As a conscientious maintenance professional, you no doubt take pride in your equipment. As such, you take the proper actions to make sure your tools are in tip-top shape. Your camera is no different. You make sure to keep it secure in its case when you transport it, you protect it from dirt, moisture, harsh [...]
