Abstract :
This contribution focuses on the application of dielectric loss measurements for service aged oil-impregnated high voltage power cables. The results of the project focused on condition assessment of service aged oil-impregnated HV power cables will be discussed. The final goal of this project is: to develop by using laboratory and on-site tanδ measurements a tool to support the condition assessment and asset management decisions. By combination laboratory measurements and on-site diagnostics, an investigation have been performed into several complete cable circuits to find the relation between electrical and thermal stresses of paper oil-impregnated insulation, at different aging stages. The result of this investigation, in particular influence of electrical and thermal stressing of samples in different stage of aging, with combination of on-site diagnostics has been applied to develop a tool for supporting asset management decision process.
