| Abstract: | An efficient method is proposed in this paper to calculate the electrical parameters of conducting branches in the building lightning protection system. The capacitance matrix of conducting branches is determined in terms of the average potential method. Moreover the impedance(inductance) matrix of conducting branches is calculated by Neumaan' s formula. In order to check the validity of the proposed method, a comparison is made between calculated and experimental results. A better agreement in shown between them. |
