Dr. Krystian Leonard Chrzan was born in Odolanow, Poland. From 1978 to 1983 he studied Electrical Engineering at the Wroclaw University of Technology. Since 1983 he is with the Institute of Electrical Engineering Fundamentals of the Wroclaw University of Technology where he received his Dr. – Ing. in 1987. From 1988 to 1989 he was a scholar of the Alexander von Humboldt Fellowship at the high voltage laboratory of the University of Stuttgart (Prof. K. Feser). From 1991 to 1993 he worked at the high voltage laboratory of Technical University of Zittau (Germany, Prof. J. Pilling, Prof. R. Baersch) and for Cardiff University (2004-2005, Prof. R.T. Waters). He spent research stays at the high voltage laboratories in Stuttgart (1985, 1994, 1995, 1996, 1999, 2003), Dresden (1995), Mannheim (FGH,1996, 1997, 2002), Darmstadt (2002), Cottbus (2007), Prague (EGU, 2001) Lvov, Ukraine (2008), Stellenbosch, South Africa (2009, Dr. J.P. Holtzhausen), Tomsk (2010, Prof. Valentina Gorbatenko), Beijing, Shenzhen, Tsinghua University (2010 Prof. Zhicheng Guan), Bangalore, Indian Institute of Science (2011, Prof. Joy Thomas Meledath) and at the Lightning Research Center Camp Blending (2000, Florida, Prof. M. Uman). He is author or co-author of about 230 scientific papers, a book “Surge arresters for high voltages” (in Polish) and a student script "High Voltage Laboratory Training".
