Ground reflection effect on the lightning electromagnetic fields

The ground reflection at channel base is as an important factor on the values of lightning electromagnetic fields and lightning induced voltage on the power line that is due to difference between the return stroke channel and the ground impedances. In this paper, the effects of ground reflection fac...

Description
Summary:	The ground reflection at channel base is as an important factor on the values of lightning electromagnetic fields and lightning induced voltage on the power line that is due to difference between the return stroke channel and the ground impedances. In this paper, the effects of ground reflection factor on the values of lightning return stroke currents at different heights along lightning channel and also lightning electromagnetic fields are considered and the results are discussed accordingly.
