abnormal electrical resistance is evident in the pattern of localized heating at the pinch point of the switch.
Commençons cette discussion en précisant qu’il s’agit en fait de la « température apparente » des commutateurs. Tel que discuté dans nos cours de niveau I et de niveau II, les surfaces métalliques nues sont de mauvais émetteurs, et que d’essayer de pouvoir capter leur température...

Thermal imaging in Building Applications
While an infrared camera’s standard lens is likely fine for most circumstances, the option to add a telephoto or wide-angle lens can prove useful in certain building inspection situations. First, if you are new to infrared and think you may have the need for an optional...

abnormal electrical resistance is evident in the pattern of localized heating at the pinch point of the switch.
Iniciaremos aclarando que al referirnos a la temperatura en los contactos de un switch o desconexión hablaremos de ‘temperatura aparente’, pues como se indica durante nuestros cursos de Termografía de Nivel I y Nivel II, el metal sin forro o desnudo no emite mucho por lo...
