Infrared Thermography
Infrared thermography detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution.
Comstock Bros. Electric knows how to distinguish from myth and facts in this area.
FACT: Infrared heat shares most of the same properties as visible light. Infrared heat will not radiate through a panel or transformer cover just as light will not shine through them. Since moderate temperature rises in most electrical distribution systems are normal, simply viewing the cover surfaces will not suffice. The surface temperature plays a role in what is seen. Wherever safe, covers and obstructions must be removed to expose the actual electrical component for proper inspection.
FACT: Spot radiometers, also known as heat guns, by definition, can only view one small spot at a time. Since an electrical panel consists of hundreds of points, viewing them all with a spot radiometer is time and labor intensive. Infrared imaging systems, such as those used by Comstock Bros. Electric, can view an entire panel at once. Additionally, spot radiometers display the average temperature within its viewing range of approximately one square inch, so smaller hot spots are often more difficult to catch and correct.
FACT: Both true RMS and peak load readings are required to determine harmonic distortion problems.
FACT: On the contrary, equipment must be running at normal operating load to find most problems.
