摘要：
This article presents a novel type of damage detection system for power cables. The functionality of the measuring system can be verified with respect to macrobending-induced increase of attenuation. Due to the used integration approach, damage to the sheath at the power supply cable can be detected, whereby long-term failure causes can be detected at an early stage. By means of an integrated optical fiber and an optical time domain reflectometer, regardless of the electrical energy transmission in the cable, an exact and efficient damage localization can be provided, resuloting in time and cost-effectiv procedure.
