Numerical modeling of distribution of currents in the lightning protective system of a residential house

The current distribution in the lightning protective system (LPS) of a residential house is modeled by using a model based on the lumped circuit theory in the frequency domain. The injected lightning current is represented by an ideal current source. The effect of electromagnetic field radiated by the lightning channel on the distribution of currents in the LPS is taken into account. The discrete complex images method (DCIM) is used to calculate the electromagnetic field radiated by the lightning channel. The time-domain current waveforms are obtained by means of the Fourier transform technique. The calculated currents in the LPS are compared with those measured at the ICLRT in 2004 and 2005.
