DEFECTIVE DETECTING DEVICE IN A HIGH-TENSION LINE RELATED TO AN ELECTRICITY DISTRIBUTION NETWORK

摘要

Integrated casing (4), comprising sensors and electronics for detecting defects within the distribution network, has at least one conductor (14) within, which ensures that electric field lines around support pylon (6) for power cable being monitored have a known orientation. The detection device has a first sensor (10) for detection of Homo-polar current transients and a second sensor (12) sensitive to unipolar voltage transients. Electronic circuit (8) effects a fault detection based on comparison of the signs of the homo-polar voltage and current transients.
