| Pruebas de inmunidad de los equipos de telecomunicaciones expuestos a las sobretensiones y sobrecorrientes – Recomendación básica |
 |
La presente Recomendación tiene por objeto establecer criterios y métodos de prueba fundamentales sobre la inmunidad de los equipos de telecomunicaciones a las sobretensiones y sobrecorrientes.Las sobretensiones y sobrecorrientes a que se refiere esta Recomendación incluyen las descargas de rayos en las líneas o cerca de ellas, la inducción de corta duración por tensiones alternas procedentes de líneas de energía o sistemas ferroviarios electrificados adyacentes, la elevación del potencial de tierra debido a fallos del sistema de energía y los contactos directos entre líneas de comunicación y líneas de energía.Las principales modificaciones con relación a esta Recomendación versión 2000, incluyen:
• sustitución de la prueba longitudinal por una prueba basada en un puerto conectado a tierra, (puerto a tierra);
• introducción de una prueba entre dos puertos externos (puerto externo a puerto externo);
• adición de requisitos relativos al puerto interno. |
