These trees are hollow tubes that grow inside the insulation under the action of partial discharge (PD) activity; therefore, PD analysis is key to diagnosing polymeric insulation. Two traditional methods for PD analysis are Phase Resolved PD (PRPD) patterns and Pulse Sequence Analysis (PSA). More recently, the use of nonlinear time series analysis (NLTSA) for PD analysis was proposed. A key concept in NLTSA is stationarity; although its formal definition does not apply to experimental data, almost all methods of NLTSA require stationarity. This research uses the Cross Prediction Error (CPE) algorithm to analyze stationarity in PD time series from electrical trees. Their results are evaluated through PSA and PRPD patterns, and NLTSA. This paper shows that tools that consider the information of PD sequences, such as PSA and NLTSA, are more sensitive to stationarity. Therefore, these tools can better detect changes in PD dynamics, thus helping to improve polymeric insulation diagnosis. Furthermore, the results suggested that CPE algorithm could detect changes in PD dynamics since it allows a time-resolved evaluation of stationarity.","PeriodicalId":374945,"journal":{"name":"2022 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131354555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reflect the practical working condition of MMC-SM, the self-healing characteristics of MFC in MMC-SM under DC and AC superimposed voltage with harmonics were studied in this paper. A film level experimental platform was built, in which the specimens were double-layer metallized film elements. A parallel superimposing circuit was adopted, where the DC voltage and the AC voltage containing harmonics were applied with independent sources. The self-healing breakdown voltages were recorded and analyzed by the Weibull distribution. It was found that the harmonic components have a significant effect on the self-healing characteristics of MFC. As the harmonic component of the applied voltage increases, the self-healing breakdown voltage decreases. Besides, the shapes of self-healing areas are distinct in different regions of double-layer films, which are highly related to the local film square resistances of the breakdown spots.","PeriodicalId":374945,"journal":{"name":"2022 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115098632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems do not use pressure resistant enclosures, but instead rely on the encapsulating material to transfer the forces to the embedded components and to provide electrical insulation and protection against water and corrosion. When designing high voltage, high power electronic systems on printed circuit boards (PCBs), the choice of encapsulating material and the integrity of the interfacial boundaries are critical to ensure adequate insulation. In this study, the effect of water ingress on the high voltage breakdown behaviour between two tracks on an encapsulated PCB is investigated. A group of PCBs, with different gaps between their conductive tracks, are encapsulated in an RTV-silicone gel and then immersed in de-ionized-and sea-water respectively to study its breakdown voltage and discharge characteristics over time. Prolonged immersion in deionised water shows a reduction in the breakdown strength between the tracks as well as anomalous breakdown on the rear surface of the PCBs whereas the breakdown behaviour did not change significantly over the evaluation period for the sample immersed in seawater. These results may have been caused by weak bonding between surfaces and the deposition of salts in the outer layer of the test specimens.","PeriodicalId":374945,"journal":{"name":"2022 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121317245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
