Abstract
The boundary element analysis of the protection zone of a metallic post, as one
of the most commonly used lightning protection devices is presented in the paper.
The calculation of induced charge density is carried out via the potential
coefficients approach. Some illustrative numerical results related to the various
engineering applications are also presented.
1 Introduction
Electromagnetic interferences (EMI) on electrical equipment are caused by a
direct lightning strike or by an indirect discharge in a close proximity of the
lightning channel [I]-[5]. Such lightning flash surges can produce adverse effects
on electrical equipement.
The key-point in the analysis of lightning protection devices is the
determination of the protection zone. The protection zone is
