Vale la pena examinar la idea, pero la implementación
real no es tan sencilla. Si el cable externo de fibra óptica está
perfectamente ubicado para aplicaciones de mantenimiento
(detección de cambios en las condiciones circundantes, cruces desconocidos de fuentes de calor, secado de suelos, etc.),
estaría demasiado lejos de los cables de alimentación para
capturar con precisión los cambios dinámicos de temperatura. Por lo tanto, esta configuración no es suficiente para
implementar una función efectiva de clasificación térmica en
tiempo real (RTTR, por sus siglas en inglés).
El desafío es instalar sensores lo más cerca posible del conductor integrando fibras ópticas directamente en los cables de
alimentación. Esto debería proporcionar mediciones de temperatura más rápidas y precisas, que formarán la base de una
solución RTTR eficiente. Para confirmar el concepto, tres
cables de alimentación en un nuevo enlace subterráneo estarán equipados con fibras ópticas integradas (gráfico 3). Este
proyecto piloto determinará si las fibras integradas permiten
obtener suficientes mediciones de variación térmica y, de
este modo, decidir si la RTTR es un sistema efectivo. Como
medio para comparar las variaciones de temperatura, también se monitoreará el cable externo de fibra óptica.

Otra forma de mejorar la operación de la red es reducir el
tiempo de inactividad de los activos por fallas (con una duración de días a semanas) y acciones de mantenimiento periódico que requieren desenergización (que duran de horas a
días). Con ese fin, se han instalado varios dispositivos de
monitoreo en un circuito para evaluar el proceso de envejecimiento del equipo, estimar el estado del equipo en tiempo
real, mejorar las prácticas de mantenimiento, evitar fallas
importantes y optimizar el trabajo de reparación cuando
