“…By the development of the simulation programs it is possible to determine the peak current in the conductor of lightning protection system and analysis the magnitudes of voltages affecting the lightning protection system, which are very important issues for protection requirements and safety. Recently, by the help of development in the software, new simulation models for the analysis and design purposes of building protection have been proposed [6][7][8][9][10][11][12]. In [6], the electromagnetic behavior of control building and power system under lightning surge strike was introduced.…”

“…The influences of ground resistivity, the lightning stroke point, and wave shape of the lightning surge on transient ground potential rise are investigated. In [12], it was indicated that the performance of protection systems and methods used against direct lightning strikes varies from system to system to be protected. In order to evaluate the effectiveness of protection methods from lightning overvoltage and current, information of potential difference at the stroke points and current transmitted to ground are required.…”

Multi-storey buildings with occupied highly technological instruments have more attraction possibilities of a lightning stroke than ordinary residential buildings. A protection system against lightning is necessary for these buildings and the level of the protection system performance is an issue to be examined. In this study, a protection system for a three-storey building is simulated in Alternative Transient Program-Electromagnetic Transients Program (ATP-EMTP). Distributed-parameter line models are used for the conductors of the protective system by modelling vertical conductors as nonuniform lines. The currents flowing in the critical conductors and the voltages at some critical points resulting by a lightning stroke are computed. The conventional lighting parameters required for structural protection such as lightning peak current, current rise time and time interval for the current flowing are determined. The effect of the radius of conductors in the protection system on the surge response is investigated.
