The partial discharge (PD) classification for electric power equipment based on machine learning algorithms often leads to insufficient generalization ability and low recognition accuracy. To solve the problem, this article develops an improved Wasserstein generative adversarial network with gradient penalty (WGAN-GP) data augmentation model. WGAN-GP model can generate samples supplement low-data input set in PD source classification. First, conditional generation is trained various new are...
Partial discharge (PD) test has been widely used in condition assessment for power cables. However, extinguish phenomenon occurred PD detection hinders the effective of potential defects cable accessories. For this reason, a novel method based on thermal excitation is proposed article to eliminate and detect earlier stage. First, physical processes activity reasons extinguishing are introduced. Then, principle mechanism described analyzed respectively, that by external heating break dynamic...
Currently employed features for separating partial discharge (PD) pulse signals are proposed based on captured by a particular sensor. If these used to separate PD other sensors, the distribution of may overlap, making it difficult distinguish different signals. To address challenge poor applicability traditional sensors with amplitude–frequency characteristics in signals, this article proposes time–frequency (T–F) feature extraction method t-distributed stochastic neighbor embedding...
Time domain reflectometry (TDR) is an effective method used to detect partial discharge (PD) and localize PD sources on power cables. However, for long-length cables, the attenuation dispersion of signals are significant due propagated distance. The causes a serious reduction pulse amplitude, which makes defects located far away from detector difficult find. appreciable asymmetry in wave form. Thus, localization accuracy reduced. To solve problem cable fault localization, novel signal relay...
Background Greenness exposure is beneficial to human health, but its potential mechanisms through which the risk for metabolic syndrome (MetS) could be reduced have been poorly studied. We aimed estimate greenness-MetS association in southeast China and investigate independent joint mediation effects of physical activity (PA), body mass index (BMI), air pollutants on association. Methods A cross-sectional study was conducted among 38,288 adults based Fujian Behavior Disease Surveillance...
Altered expression of six-transmembrane epithelial antigen prostate 4 (STEAP4) is linked to obesity, insulin insensitivity, metabolic homeostasis, and inflammation. This study assessed STEAP4 single nucleotide polymorphisms (SNPs) for association with a risk in developing syndrome Han Chinese population.A total 3375 subjects were included this case-control 1583 (MetS) patients 1792 healthy controls. Four SNPs (rs1981529, rs2040657, rs10263111, rs12386756) genotyped using polymerase chain...
In this study, the inhibition effect of electrical treeing is investigated in a cross-linked polyethylene (XLPE) cable under targeted movement rejuvenation fluid induced by an electric field. First, concentration around defects characterized Fourier transform infrared (FTIR) spectroscopy different voltages, application durations, and temperatures. These results show that with increasing applied voltage, duration, temperature, increases nonlinearly. Next, features samples without field...
Moisture at the insulation interface is main cause for electrical breakdown and failure of cable accessories. However, it still unclear how presence moisture affects discharge development interfacial process. This paper clarifies reasons accessory interfaces under effect moisture. First, characteristics faulty accessories in field are presented. Second, evolution during process dry wet experimentally described. Then, mechanism on explained by combining product analysis electric analysis....
Abstract Objectives: Circadian system is an essential physiological regulator of mammals, and circadian dissonance may be associated with the risk metabolic disorders. However, evidence regarding its role in development metabolic-associated fatty liver disease (MAFLD) scarce, particularly employed adults. Methods: We conducted a longitudinal study 1,309 adults Southwestern China five-year follow-up from 2017 to 2021. MAFLD was assessed by presence hepatic steatosis using abdominal...
Abstract Background: Non-mutational mechanisms were recently discovered leading to reversible drug tolerance. Despite the rapid elimination of majority tumor cells, a small sub-population ‘‘drug-tolerant’’ cells remain viable with lethal exposure, which may further lead resistance or relapse. Several signaling pathways are involved in local systemic inflammatory responses contributing drug-induced phenotypic switch. Results: In this study, we report Toll like receptor 4 (TLR4)-interacting...
