\u00a1Por fin! El umbral de 40 cal\/cm2 puede finalmente ser eliminado.<\/strong><\/p>

Durante muchos a\u00f1os, el umbral de 40 cal\/cm2 que forma parte de la Nota informativa 3 que actualmente se encuentra en la edici\u00f3n 2015 de la Secci\u00f3n 130.7(A) de NFPA 70E ha sido objeto de constante debate.\u00a0<\/p>

\"BUY<\/a><\/p>

El texto vigente establece:<\/p>

Nota informativa n.\u00ba 3: Cuando la energ\u00eda incidente supere las 40 cal\/cm2 a la distancia de trabajo, puede ser necesario hacer mayor hincapi\u00e9 en la desenergizaci\u00f3n cuando se exponga a peligros el\u00e9ctricos.<\/em><\/p>

La raz\u00f3n que se cita con frecuencia para utilizar el umbral de 40 cal\/cm2 en la Nota informativa 3 era la protecci\u00f3n del trabajador contra la presi\u00f3n de la explosi\u00f3n. Este valor se seleccion\u00f3 como un punto en el que la presi\u00f3n de la explosi\u00f3n se consideraba un peligro significativo y, por lo tanto, se deb\u00eda dar mayor \u00e9nfasis a la desenergizaci\u00f3n.<\/p>

Las dos variables principales que definen la magnitud de la energ\u00eda incidente potencial de un arco el\u00e9ctrico son el cortocircuito del arco el\u00e9ctrico y la duraci\u00f3n del arco, definida por el tiempo que tarda un dispositivo de protecci\u00f3n en eliminar el evento. Esto significa (como muchos saben) que una corriente de cortocircuito del arco el\u00e9ctrica baja con un tiempo de eliminaci\u00f3n del dispositivo de protecci\u00f3n inusualmente largo determinado a partir de la curva de tiempo-corriente del dispositivo, puede dar como resultado una energ\u00eda incidente calculada muy grande, que a menudo supera el umbral de 40 cal\/cm2.<\/p>

\"Download<\/a><\/p>

Sin embargo, la presi\u00f3n de la explosi\u00f3n NO es una funci\u00f3n directa de la energ\u00eda incidente. Es una funci\u00f3n de la corriente de cortocircuito y de la velocidad de liberaci\u00f3n de energ\u00eda. Aunque puede ser posible calcular un valor de energ\u00eda incidente muy grande debido al tiempo de despeje de un dispositivo de protecci\u00f3n, no es un verdadero indicador de la presi\u00f3n de la explosi\u00f3n.<\/p>

La edici\u00f3n 2018 de la NFPA 70E (Norma para la seguridad el\u00e9ctrica en el lugar de trabajo) puede finalmente eliminar la Nota informativa 3 y el umbral de 40 cal\/cm2. Seg\u00fan las presentaciones de aportes p\u00fablicos para el primer borrador y la declaraci\u00f3n del comit\u00e9 de la NFPA 70 correspondiente, parece que se eliminar\u00e1 la Nota informativa 3, ya que siempre se debe hacer mayor hincapi\u00e9 en la desenergizaci\u00f3n independientemente del nivel de energ\u00eda del incidente.<\/p>

Aunque todav\u00eda quedan varias etapas antes de que esto se concrete, la eliminaci\u00f3n de la Nota informativa 3 ser\u00eda un cambio bienvenido que contribuir\u00eda en gran medida a eliminar la confusi\u00f3n (y a veces el p\u00e1nico) que resulta cuando se supera el umbral aparentemente arbitrario de 40 cal\/cm2.<\/p>
