Conference in Japan: Interview with our PhD student Sandra Plötz after the ISH2025 Conference

Interviewer (I): Sandra, could you give us an insight into your research?

Sandra: Of course! In my paper, I investigate the influence of connected elements, particularly cables, on frequency response analysis (FRA) in rotating machines.

I: That sounds fascinating! Why is this topic so important?

Sandra: FRA has already been successfully applied to power transformers and shows great potential as a diagnostic method for rotating machines. One challenge lies in distinguishing the effects of connected components, such as cables or converters, from actual faults within the machine itself. This improves the reliability of diagnostic results, regardless of whether measurements are performed offline or online.

I: What kind of practical changes could these findings bring about?

Sandra: Through my research as part of the EFRoM project, we are gaining a deeper understanding of FRA measurements by specifically considering the influence of connected elements. In the long term, we hope that this will meaningfully complement existing measurement methods for rotating machines and enable more reliable detection of various types of faults.

I: Thank you, Sandra, for this exciting insight! We look forward to hearing more about your future findings!

Sandra: Thank you! I’m glad to share my knowledge and research at Munich University of Applied Sciences / Institute for Sustainable Energy Systems.
