This book presents proven lightning and surge protection measures, taking into account the latest standards and engineering. The components and devices that are used to achieve these protective measures are explained in terms of their function and application by means of practical examples.

Electromagnetic compatibility (EMC) engineering usually proceeds from an interference model consisting of a source of interference (transmitter), a coupling mechanism (path) and a potentially susceptible equipment (receiver). Electrical systems with electronic devices as potentially susceptible equipment are endangered by conducted interferences and interfering radiation from the following six sources of interference: i.) direct and close-up lightning discharges; ii.) power technical switching operations; iii.) power technical system perturbation; iv.) electrostatic discharges; v.) low and high frequency transmitters; and vi.) nuclear explosions. In the following sections, lightning discharges and switching operations as sources of interference are described according to their priority.

In this chapter components and protective devices used for surge control and/or the realization of the EMC-oriented lightning protection zone concept will be introduced with particular regard to construction, mode of functioning and fields of application.

This book has introduced practice-proven components and protective devices by which it is possible to plan and realize complete lightning/surge protection concepts for many kinds of complex systems and structures. The protective measures exemplified and devices available are applicable, not only in new projects but also in existing systems which can be retrofitted so that a sufficient protection can still be attained. Subsequent installation, however, will be at higher cost and with a lower efficiency.
