T&D '24 Tutorial: Advanced Techniques for Safeguarding Aging Power Cable Networks through Testing and Diagnostics (Slides)

There are several test and diagnostic methods available to assess and determine how these stress factors have affected the integrity of a cable. These methods include partial discharge, dielectric loss (Tan Delta), withstand (VLF) and insulation resistance testing. Each test and diagnostic methods provide key information for evaluating cable condition. However, this cannot be done by using one test method alone, proper evaluation is done through the combination of all tests so that a full condition assessment can be achieved. The seminar will include power cable fundamentals, common failure conditions, the importance of a maintenance program, power cable test and diagnostic methods, testing standards, test data analysis and follow up actions to poor test results. Showing how using each test method can increase cable network reliability. Since the majority of power cable systems near the end of their life expectancy, it's imperative to actively manage the life cycle of cables.
