Infrared thermography is widely applied to power systems in the power substations and in the overhead transmission lines condition monitoring, aiming at continuous operation and maintenance purposes. As applied in an outdoor environment, the themographyc inspection is influenced by a number of ambient variables such as wind, solar radiation, humidity, and so forth. A great challenge for the researchers consists in the development of methods to extract the influence of such ambient variables in order to get the most reliable diagnostic. Therefore, an acclimatiezed chamber was developed to simulate actual conditions, allowing for the development of methodologies in the laboratory for latter application in field. The purpose of the proposed paper is to present the principles that guided the development of the chamber, its automatization and to describe the tests that can automaticaly be conducted.
