2. Measuring Tower-Footing Parameters for Backflashover Assessment: Update from CIGRE WG C4.69 (in English)

Prof. Visacro is an international expert in lightning, grounding, and lightning performance of transmission lines. As a researcher, he has contributed to measurement/detection of lightning parameters as well as to experimental tests and modelling of lightning response to grounding electrodes, including methodologies to measure tower-footing impedance/resistance. As an international consultant, he has extensive experience addressing issues related to grounding and lightning protection/performance of power utility transmission lines and wind farms. He is an IEEE Fellow. recipient of IEEE Kanda, Karl Berg and Distinguished CIGRE Member Awards in recognition of his contributions to these fields, and also active as Convener and representative in CIGRE WGs. He has been ranked in the top 2% scientists in the world by Stanford University.
