Lightning current and magnetic field parameters caused by lightning strikes to tall structures relating to interference of electronic systems

In order to protect electronic devices against the effects of lightning strikes to tall structures, detailed information about the lightning currents and the radiated electromagnetic fields are necessary. For this purpose, coordinated lightning current and field measurements are performed at the telecommunication tower on the mountain Hoher Peissenberg in the south of Germany. The instrumentation is described. Of special interest are the detailed waveforms of the lightning currents and the corresponding magnetic fields as well as their respective derivatives. Electronic systems are mainly affected by the impulse current components in a lightning strike to a tall structure. The lightning current and corresponding field waveforms are discussed and detailed statistical evaluations of different parameters are presented.
