Biography

Testing Extruded Cable Systems Up to 525 kV DC: Laboratory Experience & Latest Requests From The Market

Dr. Jahn received his Degree as engineer in 1995 at the TH Zittau and a Doctor of Engineering at the TU Dresden. He started his career in 2001 at Siemens in Berlin and since 2006 is working in different positions for the FGH Engineering & Test in Mannheim, Germany in different positions. While started as head of the high voltage test laboratory, currently his position is Projects Coordinator Central Europe for KEMA Labs. He is author and co-author of several publications in the field of high voltage materials and testing.

Demand is growing for HVDC cable systems to carry high power over long distance, allow greater grid flexibility and help connect renewable energy sources to urban demand. As a result, test laboratories are receiving many requests to verify performance of such systems. This presentation reviews a feasibility study for setting up test circuits that enable laboratory testing of full-scale HVDC cable systems to verify performance and culminating in the first Transient Over Voltage test on a 525 kV DC cable system loop. Testing started with Type Tests to verify project integrity and continued with Pre-Qualification Tests to evaluate reliability as well as meeting requirements to withstand dynamic voltage stresses of non-standard nature.
