IEC 62305-3 gives two different methods for this calculation: a standard, simplified approach and a more detailed approach, which differ especially regarding the treatment of the current sharing effect on the LPS conductors. Hence, different results for the separation distance are possible, leading to some discrepancies in the use of the standard. The standard approach defined in the main part (Clause 6.3) and in Annex C of the standard in some cases may lead to a severe oversizing of the required separation distance. The detailed approach described in Annex E naturally gives more correct results. However, a calculation of the current sharing amongst all parts of the air-termination and downconductor network is necessary, in many cases requiring the use of network analysis programs. In this paper simplified methods for the assessment of the current sharing are presented, which are easy to use as well as sufficiently adequate.}, subject = {Blitzschutz}, language = {de} } @article{KernThomsen1994, author = {Kern, Alexander and Thomsen, M.}, title = {Comparison of single point and equipotential bonding for I\&C systems of large-area industrial sites}, series = {Volume of proceedings : Budapest, Hungary, September 19-23, 1994 / organized by: Technical University of Budapest}, journal = {Volume of proceedings : Budapest, Hungary, September 19-23, 1994 / organized by: Technical University of Budapest}, publisher = {Techn.

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{KernSchelthoffMathieu2012, author = {Kern, Alexander and Schelthoff, Christof and Mathieu, Moritz}, title = {Detaillierte Berechnung der Einfangwirksamkeiten von Fangeinrichtungen}, series = {Elektro-Praktiker}, volume = {66}, journal = {Elektro-Praktiker}, number = {4}, publisher = {Huss Medien}, address = {Berlin}, issn = {0013-5569}, pages = {6 Seiten}, year = {2012}, abstract = {Im Beitrag wird zun{\"a}chst das Verfahren eines dynamischen elektro-geometrischen Modells vorgestellt. Dieses arbeitet im Gegensatz zum klassischen Blitzkugel-Verfahren nicht mit konstanten Radien; vielmehr wird der Radius der Blitzkugel variiert. Dabei werden ausschließlich vorhandene und in internationalen Normen anerkannte Ergebnisse, blitzphysikalische Grundlagen und Untersuchungen verwendet, und auf deren Grundlage ein numerisches Verfahren erarbeitet. Mit dem dynamischen elektro-geometrischen Modell werden dann einige Beispiele des Schutzes mit Fangstangen, die gem{\"a}ß dem klassischen Blitzkugel-Verfahren nach DIN EN 62305-3 f{\"u}r die Schutzklassen I - II - III - IV geplant sind, untersucht. Es wird gezeigt, dass die Einfangwirksamkeiten wesentlich h{\"o}her sind als in der Normenreihe DIN EN 62305 selbst angegeben. Grund daf{\"u}r ist die Tatsache, dass das Blitzkugel-Verfahren sehr konservativ aufgebaut ist und dem Planer von Blitzschutzsystemen nur die m{\"o}glichen Stellen f{\"u}r einen Einschlag aufzeigt, ohne eine Bewertung der Einschlagsh{\"a}ufigkeit zu liefern.
