A Unique Thermal Problem Found in Certain Double-Glazed Windows
In this paper learn the findings of an investigation about a very different—and unusual—thermal pattern discovered on windows in the home of one of the authors. The cause is related to the loss of some of the insulating argon gas installed in the window during manufacturing. The authors also discovered the problem was not uncommon for certain types of windows and as they age the issues usually become more pronounced and, in some cases, result in a total failure (implosion) of the window.
IR Programs in Nuclear Power Stations in the Former Soviet Union
Read about the efforts to transfer IR technology to Soviet-designed nuclear power plants in Russia, Ukraine, and Armenia. The Snell Group faced a number of challenges during this project not typically encountered during infrared program development at facilities in the United States.
Surface Temperature Considerations
Engineers are usually taught the basic forms of heat transfer, often with the assumption that surface temperature is an independent variable driving the heat transfer. The reality is, however, that surface temperature is an interface between different forms of heat transfer and responds as a dependent variable. This paper will provide an overview of surface temperature as a response to different forms of both internal energy generation and external environment.
Thermal Profiles of Electric Motors and Their Relationship to Motor Circuit Analysis
Read about a study that was performed on twenty-one motors.
Eighteen of them were identical motors in identical service with the same model number and sequential serial numbers. This created a unique situation where motor data could be compared and analyzed.
Understanding Motor Starter Circuits
Whether it’s your first infrared inspection or you’re a veteran with hundreds of surveys under your belt, understanding the equipment under inspection is crucial to the successful identification and analysis of thermal anomalies. This paper will identify and discuss the components and potential problem areas involved with motor starter circuits. It will also look at methods of infrared inspection and illustrate some common and some not-so-common thermal anomalies.
