Abstract:
Water and electrical stress can cause degradation within cross-linked polyethylene insulation of underground power cables and this can produce failure. Water tree damage assessment of cables is thus very important and an accurate detection is desirable so that replacement is done only when necessary. This assessment is commonly done manually and in a destructive way and takes a considerable amount of time and effort. Therefore, a fast and non destructive approach is being designed at the ECE Department. Ultrasound synthetic aperture imaging has been considered in order to obtain images that can not only detect faults but also yield an image that can help on assessing the severity of the damage. By using this type of imaging, development of a cost effective real time system s feasible.
