![]() ![]() Preface This book is attached to a computer program, and it gives textual commentaries to each picture displayed on the screen. The computer program can be used without this book, because the same commentary can be also displayed and read on the screen. It depends on the decision of the user, whether the printed or the displayed text will be preferred. The book cannot be properly used without the computer program. The author developed this program for illustration of the special course LIGHTNING PROTECTION at the Budapest University of Technology and Economics. The series of this course began about 20 years ago and now more than 100 students choose it in each semester. Projecting this program, the lecturers almost never found it necessary to use blackboard and crayon. The examinations verified that many students learned, with good results, from this program. The success encouraged me to develop this version, which also contains on-screen comments and their printed form. Therefore, it can be an excellent medium for individual study at home. To understand some special subjects, fundamental knowledge of mathematics and physics is necessary, although most topics do not need them. It has been demonstrated by the great success of the presentation of the Chapter ‘The mankind in the thunderstorm’ for little children at a nursery in Budapest and for the students at Stanford University in USA. Lightning was the first electrical phenomenon seen by prehistoric man, although over 1000 years passed until scientists discovered its processes and properties. In spite of our knowledge today lightning is still a mysterious phenomenon. This program tries to give a fundamental knowledge about lightning from the meteorological phenomena to the proper behaviour in open terrain during the thunderstorm. The development of a lightning flash involves many interesting processes, which are usually unknown. The computer animation can spectacularly illustrate them, and shows how complex a phenomenon lightning is. However, the investigations have discovered many details of the lightning process, though many secrets remain unexplored. One of them is ball lightning, for which the final solution is unknown in spite of several theories. Nevertheless, the most important aim of investigations is the protection against danger and damage due to lightning.Concerning this aim, the first question is: Where will be the point of strike? According to our theory, it would be on the air termination system, avoiding the structure to be protected. Since the time of Benjamin Franklin up to now, a protected space has been presumed into which the air termination excludes the penetration of lightning stroke. Several lightning strokes demonstrated that no completely protected space exists and our knowledge about the striking process initiated a probabilistic approach to this problem. The PC program deals with this topic on the base of a new theory and calculation method to estimate the efficiency of lightning interception and to evaluate the risk of damage. It was described in the book ‘Computation of Lightning Protection’ by the author published by Research Studies Press in 1991. Nevertheless, with high efficiency, we can protect the human being and his property against damage caused by lightning. Our knowledge on the processes of lightning strokes helps to understand the operation of lightning air terminal systems. The practical application of some theoretical conclusions is illustrated with the Hungarian Standard for Lightning Protection of Structures. However, the program does not intend to replace a handbook, referring the standard aims only to show the practical application. The protection of low voltage equipment and electronic equipment against over-voltage due to lightning is an actual problem of lightning protection. This topic is dealt with on the basis of the recent international recommendations. The operation of surge protection devices can be demonstratively followed on the screen. The measurement methods and the lightning localisation systems have made great developments in the last 10 years. These are also demonstrated on screen. The author has participated over 20 times in the International Conference on Lightning Protection, since 1963, which compiles current information about lightning. Study lightning from your computer at home! Enjoy and use this program with good success!
