The Weibull model as a statistical method has been widely used for analysis of cable failure data and for prediction of future failure rate on an annual basis. However, previously published approaches cannot be relied on to model the phenomenon that higher number of failures of cable joint has been observed during summer time by Scottish Power Energy Networks (SPEN). Seasonal temperature higher than $20^{circ}mathrm{C}$ resulted in increasing failure rate of cable joints, especially for the joints which connect PILC cables. When the ambient temperature was lower than $15^{circ}mathrm{C}$, the failure rate of cable joint became smaller. This paper aims to improve the standard Weibull model to allow predictions of number of failures with consideration of seasonal temperature. The thermal stress caused due to seasonal temperature is treated as a variable to correct the failure rate obtained via standard Weibull analysis, as the number of failures has been heavily related to seasonal temperature. With the improved model, failure prediction can forecast higher number of failures during the summer season.

A novel hybrid approach for surface modification of nano-silica for polyolefin-based dielectric composites is presented. A fumed nano-silica was modified with long oligomeric chains of a liquid rubber, connected via urethane bonds to the silica surface increasing the compatibility with the matrix. Additionally, a secondary amino-silane was grafted in order to alter the charge trapping properties of the silica. The long oligomeric chains provide good dispersibility of the nanosilica in polypropylene/poly(ethylene-co-octene) (PP/POE) blends, while the functional urethane group along with a secondary amino-silane affected the charge trapping properties of the nano-composites by reducing the charge traps density and simultaneously increasing their depth. Scanning Electron Microscopy along with Differential Scanning Calorimetry revealed that the silica is preferably located in the PP phase, most likely due to its lower viscosity in comparison to POE. The silica particles exhibit a nucleating effect visible in a noticeable increase of the crystallization temperature of the PP phase, especially when the silica surface treatment is performed.

Oil-filled equipment such as inverted oil-immersed current transformers, etc., during operation, due to electric field, magnetic field, etc., the insulating oil will oxidize, crack and carbonize, causing some CH bonds and CC bonds to break through complex chemistry. The reaction is recombined to form gases such as CO, CO2, and H2. Because in the study of inverted oil-immersed current transformers, the gas generated by the head due to fault can only be detected by chromatographic analysis of the oil sample taken at the bottom of the transformer. Therefore, in order to study the law of gas diffusion from generation to stable diffusion in insulating oil, the gas diffusion distribution rule of 65kV inverted oil-immersed current transformer model was established by COMSOL simulation platform, and finite element analysis method, Multiphysics coupling analysis method were used to build the physical model and at the same time, to verify the experiment. The experimental and simulation results are mutually verified, and the diffusion distribution law of gas in insulating oil is obtained. The calculation model of gas diffusion distribution of current transformer is established, which provides a new idea for the maintenance of related equipment.

Pole-to-ground faults in HVDC transmission systems with Voltage Source Converters may cause Long Temporary Over-Voltages on the healthy pole of the configuration. This work aims at a preliminary experimental evaluation of the effect caused by the repetitive application of such Long TOVs on the XLPE insulation for HVDC cables. This paper also studies the changes in the dielectric relaxation properties, with their proposed mechanism, of 0.15 mm-thick XLPE sheets after being subjected to different levels of electrical aging due to TOVs.

Agglomerates of nanoparticles which inevitably occur in the fabrication process of epoxy nanocomposite can affect the insulation properties of epoxy nanocomposite. This paper presents an attempt to clarify the effect of agglomerate size on two important insulation properties of epoxy/TiO2 nanocomposite (NC). One is intrinsic AC breakdown strength and the other is long-term partial discharge lifetime. We used a centrifugation technique to control the maximum size of the agglomerates in the range from 5 μm down to 0.05 μm in each sample. As the results, AC intrinsic breakdown strength was increased with decreasing the maximum agglomerate size and became even higher than the neat epoxy resin when the maximum size is less than around 0.05um. On the other hand, partial discharge lifetime decreased with decreasing the maximum agglomerate size. It should be noted that the PD lifetime distinctively decreased when the agglomerate size is less than around 0.2 um indicating the existence of a critical agglomerate size which contribute to the suppression of partial discharge development resulting in the extension of the partial discharge lifetime.

In order to evaluate the strength as well as the weak points of different high voltage low attenuation polyethylene (PE) coaxial cables without semiconducting layers for pulsed applications, performance tests have been carried out. The gained knowledge shall help to produce an improved cable, suitable for the special requirements of the fast-pulsed high voltage kicker systems at CERN. The new conventional PE insulated cables are being studied to potentially replace some of the SF6 gas filled cables currently in operation.

Charge injection and transport mechanisms occurring at metal/dielectric interface may strongly impact devices performance and reliability. However, these phenomena remain partially understood, mainly due to the lack of adapted characterization tools. In this paper, we propose an investigation of the charging behavior at the Al/SiNx interface using Kelvin Probe Force Microscopy (KPFM). Indeed, KPFM measurements permit to probe space charge density with a sub micrometric resolution. Results presented here emphasize that electrons and holes are injected and trapped close to cathode and anode, respectively. The charge clouds remain stacked to the interface $(2-3 mu mathrm{m})$. Moreover, the amount of injected charges increases with the applied bias. The injected electrons and holes follow the same dissipation mechanism in time after bias removal.
发生在金属/介质界面的电荷注入和输运机制对器件的性能和可靠性有很大影响。然而，这些现象仍然是部分理解，主要是由于缺乏适应的表征工具。本文采用开尔文探针力显微镜(KPFM)研究了Al/SiNx界面的充电行为。事实上，KPFM测量允许以亚微米分辨率探测空间电荷密度。本文的结果强调电子和空穴分别在靠近阴极和阳极的地方被注入和捕获。电荷云仍然堆积在接口$(2-3 mu mathrm{m})$上。此外，注入电荷量随着施加偏压的增加而增加。消除偏压后，注入的电子和空穴在时间上遵循相同的耗散机制。

Polyethylene is widely used in submarine DC cables, but polymers have the problem of space charge accumulation. Long-term exposure to high electric field will cause space charge accumulation in polymers which will lead to severe problems. And the space charge injection will be affected by the pressure of the sea. Using the Piezoelectric pressure wave propagation method to investigate the effect of pressure changes on space charge signal, the pressure will cause the thickness of the sample to change, which will cause the position change of the space charge signal. The experiment is designed to analysis the space charge signal under high pressure, also correction is applied to the signal according to the change of thickness and sound velocity in polyethylene.

The external insulation fault of power system will cause huge loss, so it’s very important to accurately judge and predict the external insulation state. The existing detection methods of external insulation state are based on a single signal generated by discharge, which is prone to misjudgment and is not conducive to fault judgment and prediction. In this paper, the partial discharge experiment of contaminated insulator is carried out. Through the collection of the ultraviolet and infrared signals released in the discharge, data transmission and information fusion, it can provide support for the judgement of the state of the external insulation. The adaptive network-based fuzzy inference system (ANFIS) is used for information fusion of two kinds of information to diagnosis insulator running state. The accuracy of the information fusion diagnosis can reach 92%, which meets the requirements of the external insulation detection of the power system.
