Evaluation of a Single-Phase-Cable simulation model for Line Resonance Analysis

The interest in diagnostic evaluation of power cables has been steadily growing due to increasing installation length, longer service life and increased ratings for example. The existing diagnostic methods are able to localize failures, if an electrical or mechanical damage exists. Damages are for example short circuits, partial discharges, displaced or broken conductors. However, utilizing commonly available analysis, changes in cable morphology are hard to detect and even more difficult to localize on a position. These changes may include small pinholes leading to the incorporation of water, spreading out in tree like structures or an accelerated aging at a hot spot. The magnitude of these changes can be measured by a loss factor measurement. Unfortunately it is not possible to localize…
