Heat Transfer in High-Voltage Surge Arresters
, 2020 : We present results of the use of COMSOL Multiphysics for the design optimization of gas-insulated high-voltage surge arresters. By solving the equations for electric conduction and heat dissipation in nonlinear media and for heat-transport through ...

PROTECTION OF OVERHEAD LINES WITH METAL-OXIDE ARRESTERS [PDF]
, 2020 − The paper is focused on the lightning protection of overhead lines using Metal Oxide Arresters (MOA). Among many different possibilities to equip a line with arresters, the case of an overhead line without earth wire was studied, using the ATP code ...

Advanced Functional Materials, EarlyView.Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Advanced Functional Materials, EarlyView.Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...
