“…Further, Michishita and Ishii [16] showed that the Rusck model was equivalent to the Agrawal model even if the horizontal wire had a finite length. Piantini and Janiszewski [11] demonstrated that the validity of the Rusck model extended to include a strike object by comparing calculated voltages with those measured in experiments of Yokoyama et al [17], [18]. Note that in the Agrawal model, the sources are expressed in terms of electric excitation field.…”

Abstract-The aim of this study was to identify conditions under which the presence of tall strike object can serve to increase or decrease lightning-induced voltages on a nearby overhead wire. We examined the ratios of magnitudes of lightning-induced voltages on the overhead wire for the cases of strikes to a tall object and to flat ground as a function of distance from the lightning channel d, current reflection coefficients at the top of the strike object ρ top and at the bottom of the strike object ρ bot , the current reflection coefficient at the channel base (in the case of strikes to flat ground) ρ gr , and the return stroke speed v. Lightning-induced voltages were computed using the finite-

This paper focuses on the voltages electromagnetically induced by the multiple return strokes involved in a triggered lightning on an overhead power line and a vertical signal line of an automatic weather station (AWS), and the backflow currents and residual voltages in a surge protection device (SPD) embedded in the power line. Pulses of voltage on the overhead power line corresponding to the return strokes with the peak currents ranging from −6.67 to −26.47 kA showed bipolar features. Subpeaks and main peaks ranged from 0.99 to 4.47 kV and from −4.98 to −10.31 kV, respectively. The voltage waveforms corresponding to the return strokes on the vertical signal line of wind speed were of two types: with and without a subpeak after the main peak. All the main peaks, with the peak value from −0.41 to −3.10 kV, were ‘V’ shaped. A significant relationship exists between the peak currents of the return strokes and the 10–90% average gradients of the voltages. The peaks of currents through the SPD ranged from −0.22 to −1.64 kA. The durations of residual voltages ranged from 0.6 to 5.9 ms, average value being 2.1 ms. © 2013 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.

Abstract-The evaluation of electromagnetic transients in overhead power lines due to nearby lightning return strokes requires accurate models for the calculation of both the incident lightning electromagnetic pulse (LEMP) and the effects of coupling of this field to the line conductors. Considering also the complexity of distribution networks in terms of their topology and the presence of power system components and protection devices, the implementation of the LEMP-to-transmission-line coupling models into software tools used to represent the transient behavior of the entire network is of crucial importance. This paper reviews the most significant results obtained by the authors concerning the calculation of lightning-induced voltages. First, the theoretical basis of advanced models for the calculation of LEMP-originated transients in overhead power lines is illustrated; then, the relevant experimental validation using: 1) reduced-scale setups with LEMP and nuclear electromagnetic pulse (NEMP) simulators and 2) full-scale setups illuminated by artificially initiated lightning are reported. Finally, the paper presents comparisons between simulations and new experimental data consisting of measured natural lightninginduced voltages on a real distribution network in northern Italy, correlated with data from lightning location systems.Index Terms-Electromagnetic transients, electromagnetic transient program (EMTP), insulation coordination, lightning-induced transients, power quality.
