Study on the influence of rainfall on the electric field distribution and switching impulse voltage of large-size sphere–plane gap

open access: yesThe Journal of Engineering, 2019
Previously, the research about the influence of rainfall on the discharge characteristics of the gap mainly focused on the severe non-uniform electric field gap such as rod–plane, rod–rod, or tower head of which the electrode size was generally small. As

Air Quality Modeling with the Use of Regression Neural Networks

open access: yes, 2022
Air quality is assessed on the basis of air monitoring data. Monitoring data are often not complete enough to carry out an air quality assessment. To fill the measurement gaps, predictive models can be used, which enable the approximation of missing data.

Torque ripple reduction in homopolar poly-phase transverse flux machine

open access: yesThe Journal of Engineering, 2019
The problem of high ripple in output torque is inherent to switched reluctance and permanent magnet machines compared to conventional machines. Torque ripple is undesirable as it leads to increased audible noise, speed ripple, and fatigue.

Simulation of positive streamer propagation in an air gap with a GFRP composite barrier

open access: yesHigh Voltage, 2021
The puncture of glass fibre reinforced polymer (GFRP) laminate is a primary damage pattern of wind turbine blades due to lightning strikes. A numerical simulation model of positive streamer propagation in a needle‐to‐plate air gap with a GFRP laminate is
