In the introduction is described a thermographic process as part of a complex system that includes: body radiation in the infrared spectrum, transmission of radiation from the measuring object to the camera, infrared radiation conversion from analog to digital signal, showing thermograms on the screen and the human interpretation of thermograms. Parts of termovision camera and their important features are desicribed so that the functioning of the camera is understood. Every part of the installation has different functions so it is important to choose a camera that is adequate to a certain part of the installation and the method in which the termogram is processing. Connecting thermal imaging camera to a computer requires software support that gives us the results of recording in which we can see or predict a malfunction. The camera can be connected to a computer while recording as a part of a drive system. The implementation of a thermovision camera in the electroenergetic systems gives remarkable results in detection of energy losses and machine malfunctions
