Note: Refreshments will be served Abstracts Part 1: DC arcing in PV Systems and arc detection
Series arcs can cause long lasting heat sources in PV (and other DC) systems. One reason for a series arc is a very common fault of failing PV plug connections or lose or corroded screwed connections. In such a case no fuse will trigger. Hence an appropriate arc detection system has to be identified. In the talk an appropriate measurement setup and test results will be introduced and discussed.
Part 2: DC Surface Break Down
The University of Applied Sciences Upper Austria, Electrical Energy Engineering International Study Programme is working on the development of a 30 kV high voltage battery. One aspect is the application of appropriate DC insulators with special respect to polluted surfaces. Experiments at a creepage distance of 1 cm have been carried out with different insulation materials and pollution layers. First measurement results will be introduced and discussed.
Bio of Dr. Peter Zeller
Dr. Peter Zeller graduated from the Technical University Vienna in Electrical Energy Engineering.
For his PhD work he investigated the interaction of the arc plasma with the cold surrounding air in arc chutes. He was the head of the international development department for surge arresters at ABB Switzerland before joining the University of Applied Sciences Upper Austria. Currently he is the head of the international study programs of bachelor and master degrees in Electrical Energy Engineering. The courses in these programs are taught in English. Dr. Peter Zeller researches in in the fields of High Voltage Engineering, electric arcs and DC Grid technology.
Bio of Mr. Christoph Diendorfer
Christoph Diendorfer earned MSc from the University of Applied Science Upper Austria in automation engineering. His Master thesis focused on a fully automated recovery in a Medium Voltage Direct Current shipboard power system in less than 8 ms. After graduation, he started his career as a researcher in the University of Applied Science in the field of high-current engineering.
