Biography

Dimensioning of DC Porcelain & Composite Cable Terminations: Experience in Europe

Dr. Wagner completed his studies in Electrical Power Engineering and Economics at RWTH Aachen University in 2011 and received the German University Diploma (Dipl.-Wirt.-Ing.). He later worked as a Research Associate in HV insulation systems and diagnostics at the Institute for High Voltage Technology at RWTH Aachen University and received his PhD in Electrical Engineering in 2017. He is currently Asset Manager for Power Cables at German TSO, TenneT, focusing mainly on design and quality assurance of onshore and offshore HVDC cable systems. He is also involved in investigation, evaluation and implementation of advanced technologies for quality assurance, condition assessment and failure location.

Site Pollution Severity at substations is often not fully clarified and dimensioning and placement of components such as cable terminations become the responsibility of their supplier. But such an approach can sometimes results in outdoor terminations having to be placed indoors. In the case of a 525 kV HVDC station, this type of situation could also have significant impact on costs related to visual impact and land requirements arising from the height of cable terminations. This presentation explains the research methodology used to assess SPS in a specific north European coastal area and details how this information was then used in dimensioning HVDC cable terminations for this service environment.
