Abstract :
The reliability of distribution class cable systems installed in utilities can be significantly improved by employing cost effective strategies offered by innovative technologies. This will provide a better engineering tool to prioritize the capital expenditure. The on line condition assessment technology offers a non invasive, non destructive approach, which will assist the user to establish a predictive maintenance program in a proactive manner. The technique is particularly applicable for identifying the type of defects that cause aging and loss of life in system components. The rejuvenation technology extends the operating life of aged extruded cables commonly used in distribution systems. It is based on a well proven silicone fluid injection process, which is successfully employed in distribution systems all over the world.
