Cable monitoring: First field experience with DC cables

Date: 16.11.2021

Time: 3 pm CET - 9 am EST - 9 pm SGT


In some of the recent broadcasts, we have talked a lot about cable testing. In addition to factory testing, we have also shown the practical aspects of testing cables on site. Now we would like to focus on extra long HVDC cables, a technology where Germany is leading with 525 kV HVDC cable systems. Since the number of cable accessories required is much higher compared to submarine cables, the probability of failures due to defects during installation is also higher. To increase the availability of the cable system, monitoring solutions are key. Therefore, we will discuss the cable monitoring requirements. With HiMON, HIGHVOLT offers a new and advanced monitoring solution. Besides understanding the physical effects in the cable system, understanding the required signal processing and detection is of particular importance. The key to the success of monitoring systems is the availability and integration of the optimal sensor. The design and fabrication of suitable high frequency current transducer (HFCT) sensors will be discussed.

Prof. Peter Birkholz
Chair Speech Recognition & Cognitive Systems
Technische Universität Dresden


Intelligent signal processing can provide important impulses for the next-generation monitoring of high-voltage power cables.


Peter Birkholz received his Ph.D. degree (with distinction) in signal processing from the Institute for Computer Science at the University of Rostock, Germany, in 2005. After postdoctoral researcher positions at the University of Rostock from 2005-2007 and at the RWTH Aachen from 2009-2014, he became professor at the TU Dresden, Germany, in 2014. His main topics of research include articulatory speech synthesis, silent speech interfaces, and measurement techniques for speech research. Since 2018, he is cooperating with HighVolt Prüftechnik Dresden GmbH to apply modern methods of signal processing to the monitoring of high-voltage power cables. Prof. Birkholz is a member of the IEEE and the IEEE Signal Processing Society.

Dr. Christian Henze
Ritz Instrument Transformers GmbH


The energy turnaround is currently one of the biggest challenges in Germany. Ritz has the technical expertise to make an important contribution in the field of measurement, control and monitoring of the electrical energy systems.


Christian Henze studied electrical power engineering at the “Technische Universität Dresden” and was graduated in 2006 as Dipl.-Ing. Subsequently, he was a research fellow at the “Institute of Electrical Power Systems and High Voltage Engineering”. After receiving his doctorate from the TU Dresden in 2010 he has been working for the Ritz Group in various positions with a focus on product and process development. Since 2015 he has been responsible for the manufacturing processes of all Ritz Factories. In addition, he has been managing the Ritz plant in Dresden since 2019.
