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

Energy 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 ...

Mitigation of Lightning Overvoltages Using STATCOM in Grid-Connected PV Systems [PDF]

Port Said Engineering Research Journal, 2020
Lightning strike causes a large lightning voltage injection into grid-connected PV systems at the point between inverter and transformer. The overvoltage resulting from the lightning-impulse voltage is a major concern for the multiple expensive ...

The Influence of Atmospheric Overvoltages on High-Voltage SF6 Substations [PDF]

, 2011
Very fast overvoltages are characteristic of high-voltage metal-enclosed SF6 insulated substations. During the transient phenomenon, on the SF6 substation enclosure an undesired, short-lasting induced overvoltage may appear, which cannot be prevented ...

Overvoltages Transmitted in the Transformer Windings on the Lightning Impulse—An Analytical Method for Determination and Experimental Measurements

Applied Sciences
Overvoltages are brief and significant increases in the voltage level in an electrical system. They can be caused by a variety of factors, but the most common are associated with atmospheric discharges (lightning).

Overview of lightning interaction and damages to wind turbines [PDF]

, 2017
It is well known that tall structures such as telecommunication towers can be exposed to numerous lightning incidence. Wind turbines are in this group, but two particular characteristics distinguish wind turbines from the rest.

Transient Overvoltages in Onshore HVDC Cable Joints: Surge Reflections and the Influence of Grounding Configurations

High Voltage, Volume 11, Issue 1, Page 83-99, February 2026.
ABSTRACT This study examines transient overvoltage phenomena in 525 kV high‐voltage direct current (HVDC) onshore cable systems, with particular emphasis on the influence of grounding configurations in two joint types: straight‐through and screen‐separated.

Impact of steady state and impulse excitations on CuSO4 based memristor

Engineering Science and Technology, an International Journal, 2023
The memristor technology will replace nonlinear resistor applications in suppression of power system overvoltages. A characterization study on Memristance is useful to predict current–voltage characteristics of memristors under different source voltages.
