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 [...]
Reports are an essential part of our work. The professional standards I mentioned last week give good guidance on what that report should look like, at a minimum. Manufacturers like Fluke have done a superb job of developing report writing software that not only makes life simple but also produces great looking reports.
A thermographer [...]
One year ago I made some predictions about where I thought the market might be headed (click here to read full post). It is useful, I think, to see how today’s reality compares with yesterday’s dreams.
• A $1,000 imager
We are close, but thankfully not yet there. Sales of lower-cost systems continue to grow. This has [...]
Last week we talked about learning to recognize when the thermal images are in perfect focus and then practicing the techniques until you have confidence in your abilities to focus. Hopefully, no matter how long you’ve been using an imager, you’ve worked on those skills.
When you need a little extra help focusing, put the [...]
When a thermal image is poorly focused, like this of an electrical component, both accurate temperature measurement and interpretation are challenging or impossible. It is also just poor professional practice.
I hope I don’t put too many of you off with this, but I feel I must (again) revisit a couple of basic issues. This [...]
