| 3 | Surface Charging Phenomena on HVDC Spacers for Compressed SF_(6) Insulation and Charge Tailoring Strategies显示文摘Surface flashover of spacers is a key factor limiting the application of HVDC GIS/GIL,while the charge accumula-tion on the surface of the spacer could have a potential adverse effect on the surface flashover voltage.This paper discusses the laws regarding distribution patterns of surface charges and the related mechanisms.The field-dependent property is discussed in detail to comprehensively illustrate the charge transport mecha-nism and explain the research differences regarding different surface charge patterns obtained by previous researchers.In addition,the main surface charge control methods for epoxy resin are summarized and discussed.The potential research directions of charge control methods and key points in manufacturing of spacers used in HVDC GIS/GIL are also explored. | Chuanyang Li Yuan Xu Chuanjie Lin Geng Chen Youping Tu Yao Zhou Zhipeng Lei Tao Han Simone Vincenzo Suraci Jian Wang Weidong Liu M.Tariq Nazir Shun He Andrea Cavallini Giovanni Mazzanti Davide Fabiani Jinliang He | 2020 | CSEE Journal of Power and Energy Systems2020，6，1： | 3 |

| 9 | Effect of long-term fluorination on surface electrical performance of ethylene propylene rubber显示文摘To investigate the effect of fluorination on surface electrical performance of ethylene propylene rubber(EPR),four pieces of EPR specimens are prepared and fluorinated for different duration ranging from 120 min to 480 min.The surface morphology and element compositions of experimental specimens are tested.The surface potential decay and complex permittivity are measured.The tracking discharge property and the erosion properties after tracking test are investigated.The surface charge transport and electrical property tailoring mechanism are discussed.The results show that when the fluorination duration is from 120 min to 360 min,the surface morphology gradually becomes flat and compact with time,and the surface resistance to electrical tracking is improved.While an excessive fluorination with the duration of 480 min leads to a significant increase in surface conductivity and a weakening in the resistance to electrical tracking,which is mainly due to a change in surface morphology.The recommended fluorination duration for an optimised surface property is between 240 and 360 min for EPR specimen. | Rujia Men Zhipeng Lei Tao Han Davide Fabiani Chuanyang Li Simone Vincenzo Suraci Jian Wang | 2019 | High Voltage2019，4，4： | 0 |
| 10 | Guest Editorial:Interface Charging Phenomena for Dielectric Materials显示文摘Interface charge accumulation,leading to unpredictable insulation breakdown,restricts the development and industrialisation of high voltage direct current(HVDC)power equipment.Understanding the mechanism of interface charge transport and interface charge triggered dielectric breakdown is,therefore,of particularly high interest and vital importance.For example,the surface charging of aircraft in space brings damage to board electronic instruments as well as interference to sensing systems.Moreover,the randomly distributed charge clusters on the spacer surface,as shown in the cover page of this Special Issue,is considered as a potential threat to the surface flashover,while the accumulation of space charge within the insulating material poses a threat to the reliability of DC power cables.However,currently we still know very little about the development of charge dynamics in different interfaces,and the related breakdown mechanism of dielectrics induced by charge accumulation is also not very clear. | Davide Fabiani Chuanyang Li Guanjun Zhang Giovanni Mazzant Gilbert Teyssedre Jinliang He | 2020 | High Voltage2020，5，2： | 0 |

| 12 | Ageing evaluation of cable insulations subjected to radiation ageing:Application of principal component analyses to Fourier Transform Infra-Red and dielectric spectroscopy显示文摘The evolution of properties of crosslinked polyethylene(XLPE)-based insulating mate-rials under radio-chemical ageing conditions is presented and discussed.In total,seven different polymer compounds were tested,characterised by an increasing quantity of additives,for example,antioxidants(AOs)and fillers as flame retardants.Samples were analysed using different testing techniques,that is,Fourier Transform Infra-Red and dielectric spectroscopy.This allowed a broad characterisation of the polymer,bringing to good correlations between the arising of new chemical groups caused by ageing and the modifications on the complex permittivity.Phenol-based AOs are found to be the most efficient in terms of protection against oxidation.On the contrary,flame retardants are concluded not to have any impact on the material ageing.Acquired data were then treated using the principal component analysis.The data treatment successfully distinguished the material composition(with and without additives)and the ageing environments.The results confirm the relevance of this analysis in understanding the impact of irradiation on the chemical and functional properties of the polymer materials studied. | Simone Vincenzo Suraci Sandrine Amat Lea Hippolyte Astrid Malechaux Davide Fabiani Claire Le Gall Océane Juan Nathalie Dupuy | 2022 | High Voltage2022，7，4： | 0 |
| 13 | Development and pattern identification of end-winding discharge under effect of relative humidity and temperature for HV motors显示文摘During operation of high voltage(HV)motors,different types of discharges,e.g.surface discharge,corona discharge and bar-to-bar discharge can occur at the same time,increasing the difficulty of partial discharge(PD)sources determination and PDs pattern identification.In this study,the end-winding of a 10 kV motor coil was artificially aged and the related PD was measured.The initiation and variation of different PDs under multi-factor stresses were studied.The localised fingerprints coexisting with multiple PDs were identified and analysed.The results confirm that the end-winding discharge process was significantly influenced by the experiment relative humidity(RH)and temperature.The bar-to-bar discharge was easily recognised at a lower voltage since the identification of bar-to-bar discharge pattern would be affected by the corona discharge pattern at a higher voltage.It is shown that it is more difficult for the corona discharge to be detected when RH exceeded 80%,while the surface discharge dominated at the higher RH.In addition,the PDs were more easily identified with the rise of the temperature.This study can provide a reference in PD identification test and be useful for the PD online monitoring of HV motors. | Ailiang Kang Muqin Tian Chuanyang Li Jiancheng Song Simone Vincenzo Suraci Wei Li Lingyan Lin Zhipeng Lei Davide Fabiani | 2020 | High Voltage2020，5，4： | 0 |
