Based on a risk analysis protection measures against direct strikes and overvoltages are shown in an overview. The design concept is realized exemplarily for the hybrid-system VATALI on the Greek island Crete. VATALI, not lightning protected at that time, was a victim of a lightning strike in the year 2000 causing destructions and damages of some mechanical and electrical components with costs of approx. 60.000 €. The hardware costs for the protection measures were about 15.000 €: about 50\% of the costs are due to protection measures against direct strikes, 50\% are due to overvoltage protection.}, language = {en} } @article{GebhardtSchmidt2002, author = {Gebhardt, Andreas and Schmidt, Frank-Michael}, title = {Practical experiences with making and finishing of coloured models using 3D printing}, year = {2002}, language = {en} } @book{ThielemannBachem2002, author = {Thielemann, Frank and Bachem, Claus}, title = {{\"U}berlegungen zur Evaluation von Technologief{\"o}rderprogrammen}, publisher = {nst. f{\"u}r Wirtschaftswiss.}, address = {Braunschweig}, isbn = {3-933628-42-3}, pages = {48 S : graph.
