Energy Science &Engineering, EarlyView.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 ...

Transformation in substation automation: Cyber-Resilient Digital Substations (CyReDS) in power grids
at - Automatisierungstechnik, 2023 AbstractThe digitalization of substations leads to a high degree of automation, which is referred to as Digital Substations with the use of the IEC 61850. An increase in cybersecurity is necessary, and technically enabled by detection and incident response systems – security-by-design is currently often secondary.

High Voltage, EarlyView.ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.
