Abstract

Sistema de detección de arranque de cables en las redes de media tensión y procedimiento de modificación de un sistema existente. El sistema de detección de daños en los cables en las redes de media tensión, tales como las redes de alumbrado público HT.EP, está destinado a asegurar una función de vigilancia de red sin tensión y comprende medios para efectuar la medición dinámica de la resistencia (R) o de la impedancia (Z) de la red con una frecuencia de adquisición determinada, y medios de registro de los valores medidos. Está caracterizado porque la frecuencia de adquisición se fija a un nivel suficientemente elevado para permitir determinar la forma (C{sub,l}, C{sub,2}) de cualquier variación rápida de la magnitud medida que pueda producirse durante un incidente en la red. La invención se refiere, también, a un procedimiento de modificación de un sistema, existente de detección de defecto de aislamiento en una red de media tensión.Cable start detection system in medium voltage networks and modification procedure of an existing system. The cable damage detection system in medium voltage networks, such as HT.EP street lighting networks, is intended to ensure a voltage-free network monitoring function and comprises means to perform dynamic resistance measurement (R) or the impedance (Z) of the network with a determined acquisition frequency, and means of recording the measured values. It is characterized in that the acquisition frequency is set at a sufficiently high level to allow determining the form (C {sub, l}, C {sub, 2}) of any rapid variation of the measured magnitude that may occur during an incident in the net. The invention also relates to a method of modifying an existing insulation defect detection system in a medium voltage network.
