Why electrical thermography is very important
Infrared radiation is electromagnetic radiation in a specific wavelength range. By using the radiation intensity and other important factors such as the emissivity the temperature is calculated.
The measurements can be performed without turning off the connected loads, but there have to be visual contact with the system to be tested.
Exemplary sources of errors which occur millions of times
|Not be seen with the naked eye - the infrared camera makes it visible: The fuse may have a contact problem.|
|Here is a similar situation: compared with other inductors this one has an unusually high temperature. This should be analyzed in more detail!|
|Four identical machines: 2 are excessively heated. This error was discovered only with the help of the infrared camera!|
