Surface charging of dielectric barriers in short rod-plane air gaps – experiments and simulations
(Chapter, 2018)Surface charge on dielectric surfaces can alter the field conditions of insulation systems substantially. In this work, lightning impulse experiments are compared with a simulation model for surface charging in rod-barrier-plane ... -
Surface charging of dielectric barriers under positive lightning impulse stress
(Chapter, 2017)The complex geometry of gas-insulated substations makes it difficult to predict withstand voltages. A key challenge is the characterization of the interaction between electrical discharges and dielectric surfaces. A 60 mm ... -
Surface Diffusion of Oxygen Transport Membrane Materials Studied by Grain-Boundary Grooving
(Journal article; Peer reviewed, 2016)Mass transport mechanism responsible for grain-boundary grooving during thermal annealing of polished ceramics of Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) and La2NiO4+δ (LN) was revealed by atomic force microscopy. Surface diffusion ... -
Surface Effect Ship with Four Air Cushions Part II: Roll and Pitch Damping
(Peer reviewed; Journal article, 2019)This paper introduce damping of roll and pitch motion on a Surface Effect Ship (SES) in low vessel speeds. The SES consist of two side-hulls, a reinforced rubber bow and stern seal skirt system and four air cushion. The ... -
Surface electromyography normalization affects the interpretation of muscle activity and coactivation in children with cerebral palsy during walking
(Peer reviewed; Journal article, 2020)Investigating muscle activity and coactivation with surface electromyography (sEMG) gives insight into pathological muscle function during activities like walking in people with neuromuscular impairments, such as children ... -
Surface Flashover over a Micro-Profiled Cylinder in Air
(Peer reviewed; Journal article, 2023)Increasing the lightning impulse (LI) flashover voltage of insulators can require significant changes to the geometry and material properties of the insulator or electrodes. In some cases, such changes can be difficult to ... -
