Inspection with thermography is a non-invasive, non-destructive process used in Power Systems facilities. Most temperature signatures that are not in the visible light range can be measured using thermal cameras, thus enabling the search of thermal b

Circuit breakers, disconnectors, fuse disconnectors and fuse holders installed in LV electric panels sometimes suffer overheating, mainly due to inadequate dissipation of the heat generated. A theoretical and experimental investigation is attempted o
