An Experimental Study of Lightning Overvoltages on a Small-scale Wind Turbine Model

open access: yesEnergy Procedia, 2019
This paper is aimed at determining the transient induced overvoltages along a wind turbine (WT) exposed to a lightning strike. During lightning strike, the WT carries excessive currents resulting in a high voltage rise of the WT, which can cause severe ...

The Generating Mechanism and Suppression Measure of the ‘Wheel‐Rail’ Rolling Arc for Electrified Trains

open access: yesHigh Voltage, Volume 11, Issue 2, Page 370-384, April 2026.
ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system.

Time‐Domain Geoelectrical Modeling and Experimental Validation of Ground Potential Rise in Multilayer Soil Structures during Fault Events

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1492-1504, March 2026.
This study develops a time‐domain geoelectrical model of ground potential rise (GPR) in multilayer soil that couples electromagnetic field theory with nonlinear fault arc resistance. Finite‐element simulations calibrated against scaled fault‐injection experiments reproduce measured GPR and step/touch voltages within 4.7% error, revealing that steady ...
