The utility systems use a variety of circuit breakers for switching and circuit protection. These breakers can be many different voltages and vary in insulation medium from air, vacuum, gas, and oil. All of these switches have different IR characteristics. In order for the thermographer to accurately analyze the IR data it is important that he has extensive knowledge of the type switch and the internal configuration of the contacts.
