| 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 o 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 CA 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.
En comparación con la Recomendación UIT-T K.45 (2018) los cambios incluyen:
• prueba de resistencia al aislamiento CC;
• una nuevo Anexo sobre requisitos especiales. |
