Analysis of Lightning Transients in a Commercial Building Using the PEEC Method

Abstract

This paper analyzes the lightning transients in a commercial building with a grid like structure. The simulation is performed by using the Partial Element Equivalent Circuit (PEEC) method. Both the skin effect of the conductors and the nonlinear protection devices are taken into consideration. The current distribution in the structure, the induced voltage in the wiring system with different SPDs installations and the current sharing in the wiring system are discussed. Finally, suggestions are provided for effective protection against lightning in buildings.
