| Inmunidad de los equipos de telecomunicaciones instalados en locales del cliente a las sobretensiones y sobrecorrientes |
En la Recomendación UIT-T K.21 se especifican los requisitos de inmunidad y procedimientos de pruebas para los equipos de telecomunicaciones conectados o instalados en los locales del cliente.
Las sobretensiones o sobrecorrientes a que se refiere esta Recomendación incluyen las descargas de rayos en las líneas o cerca de ellas, la inducción de corta duración causada por líneas de alimentación de corriente alterna (CA) o sistemas ferroviarios electrificados adyacentes, la elevación del potencial de tierra debido a fallos del sistema de energía, los contactos directos entre líneas de comunicación y líneas de energía, y las descargas electrostáticas (ESD). Las fuentes de las sobretensiones en las líneas internas son fundamentalmente acoplamientos inductivos provocados por descargas del rayo o las corrientes del rayo inducidas en pararrayos o conductores cercanos. |
