Abstract
Un procedimiento para detectar sobrecalentamientos en un aparato eléctrico que comprende: a) pintar la zona del aparato eléctrico expuesta a sobrecalentamiento con una composición de pintura formadora de partículas térmicamente, que comprende una resina orgánica con una temperatura de formación térmica de partículas inferior a 250ºC y de 0,01 a 0,5% de un marcador químico seleccionado entre compuestos orgánicos aromáticos policlorados, compuestos orgánicos aromáticos polifluorados y compuestos orgánicos alifáticos polifluorados, con una temperatura de descomposición por lo menos 100ºC más alta que la de la resina formadora de partículas térmicamente y con un intervalo de volatilidad equivalente al de las parafinas alifáticas C24-45¿ por lo menos en dos lugares diferentes con un marcador químico diferente en cada lugar; b) en los casos donde se crea una condición térmica capaz de producir humos de la resina orgánica, transportar el humo a un monitor de núcleo utilizando un detector de cámarade ionización, basándose en la circulación de hidrógeno refrigerante, empleándose un colector para recoger las partículas de humo para su análisis.
