Assessment of the Transient Response of Wind Turbine Grounding Systems to Upward Negative Lightning

This paper presents some results of simulation of the resulting ground potential rise (GPR) in wind turbine grounding systems in response to typical current pulses pertinent to upward negative lightning. The analyses consider two different current pulses,

Modeling lightning strikes to tall towers

In this chapter, we present a review of recent progress in the modeling of lightning strikes to tall structures. Since some tall structures are struck by lightning several tens of times per year, they can be used as ground-truth to measure and calibrate ...

Inferring the Correlation Between Lightning Events and Voltage Dips in Distribution Networks

, 2007
– To appropriately infer the correlation between lightning events and flashovers/voltage dips on real distribution networks, data coming from lightning location systems are certainly needed, but need to complemented on the one hand by data coming from ...

Fundamentals of Coupling of Lightning Fields to Overhead Lines

Lightning can induce unwanted currents and voltages on overhead lines that can have a significant impact on power quality and calculating the overvoltages is essential to designing and optimizing lightning protection to minimize nefarious effects.
