Abstract As one of the weakest points in high-voltage direct current (HVDC) cables and accessories, accumulation space charges at crosslinked polyethylene (XLPE)/ethylene propylene diene monomer (EPDM) interface coated with silicone oil is crucial to insulating properties. The physical mechanisms underlying this charge dissipation phenomenon remain unclear, particularly molecular level. Thus, interfacial behavior EPDM/XLPE, EPDM/non-polar dimethyl (PDMS)/XLPE, EPDM/polar fluorinated...
With the increasing use of HVDC and MVDC assets, fundamental topic space charge measurements in full-size cables has to be faced properly. Space can a significant threat DC insulation system reliability. In this paper, development an innovative Pulsed Electro-Acoustic (PEA) device measure distribution is presented. Issues related real cable structure, thickness, (and thus signal attenuation), noise are dealt with. Specifically, effect different types electrodes, materials on PEA measurement...
Attention deficit hyperactivity disorder (ADHD) has a significant impact on individual health and society. This study aims to analyze the disease burden of ADHD in China from 1990 2019 make predictions provide basis for formulation corresponding prevention control strategies by government. Using data Global Burden Diseases (GBD) database, we described changes incidence, prevalence, disability-adjusted life years (DALY) 2019. An autoregressive integrated moving average model (ARIMA) was used...
