ITU-T K.45 (07/2017)

Inmunidad de los equipos de telecomunicaciones instalados en las redes de acceso y troncales a las sobrecorrientes y sobretensiones

La Recomendación UIT-T K.45 especifica los requisitos de inmunidad y los procedimientos de prueba para los equipos de telecomunicación instalados entre centros de telecomunicaciones y entre un centro de telecomunicaciones y los locales del cliente.
Las sobretensiones y sobrecorrientes que abarca esta Recomendación incluyen las sobrecargas debidas al rayo en las líneas o cerca de ellas, la inducción de corta duración procedente de líneas de distribución de energía eléctrica de c.a. o sistemas de tracción ferroviaria adyacentes, la elevación del potencial de tierra debida a fallos del sistema de energía, los contactos directos entre líneas de telecomunicación y líneas de energía, y las descargas electroestáticas.
Las principales modificaciones con respecto a la versión de 2013 de esta Recomendación son, entre otras:
• nuevos requisitos de pruebas para Ethernet UTPE;
• nuevos requisitos de pruebas para Ethernet STPE;
• nuevos requisitos de prueba para PoE;
• nuevas pruebas de apantallamiento STPE.
