Summary

The aim of the work was to define methods for dielectric diagnosis and to perform RRTs on examples (new material samples). The achieved results exceed the expectations by far, since additionally the methods were not only applied to new materials but also to artificially aged materials. This shows the enormous potential of FDM diagnosis to detect volume related ageing processes in insulating materials (polymer, composite and interfaces of composite materials) and complete insulation systems (cable accessories, transformers, insulators, bushings etc.). Further investigations for the application to complex insulations and insulation systems are recommended.
