The thermal aging of the PET films was shown to have a complex nature, expressed most markedly during the TSD measurements by changes of the space-charge peak maximum value. This behavior was found for all types of film. The peak change rate can be represented as a linear function of both the aging temperature and the expected time to withstand that thermal stress, estimated on the basis of the IEC 216 standard test. It is not possible at the present stage of study to estimate directly from the TSD measurements an equivalent to the temperature index, despite an existing correlation. Therefore, the method seems to be suitable for accelerated periodic monitoring of PET films whose thermal endurance characteristics are already known.<<ETX>>","PeriodicalId":184126,"journal":{"name":"Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics","volume":"447 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123874307","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}

As these tapes are very poor dielectrics with low breakdown stress, it was expected that the breakdown tests would be impaired. On the contrary, the life expectancy was raised from less than 10 years to more than 30 years at 10 kV. Further study revealed that this dielectric improvement was caused by a considerable reduction of the discharges in the interstices of the cable; reductions of several hundred times were measured. The fibers at the air-dielectric interface appear to act as barriers for the surface discharges.<<ETX>>","PeriodicalId":184126,"journal":{"name":"Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124948214","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}

The results clearly demonstrated the importance of shape factors for the formation of a conducting network and percolative charge transport in composite systems. The results are in agreement with the previous data, which have shown that very low values of threshold contents of conducting fillers are observed for large particle-length-to-diameter ratios. Other results confirmed the assumption that the decrease of electrical conductivity of samples after the critical field is exceeded is caused by breaks of the conduction network at the weak points, and that the electrical conduction of low-conduction samples is probably dominated by injection of charge carriers, fluctuation-induced tunneling, and prebreakdown effects.<<ETX>>","PeriodicalId":184126,"journal":{"name":"Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125790053","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}

However, in both SiNSi and SiOSi films, water molecules activate initially inactive intrinsic acceptor centers. As a result the electrical conductivity increases in organosilicon films in the presence of absorbed water.<<ETX>>","PeriodicalId":184126,"journal":{"name":"Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126661926","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}

Most of these cables, removed from service after six to fifteen years, contained large water trees. The results give an ambiguous picture of the role of oxidation on water treeing. The experimental difficulties in the detection and evaluation of the amount of oxidation in water trees are discussed. The results of water tree growth tests on XLPE cable insulation preoxidized in air to the level similar to that observed in field-aged cables after many years of service show that increased oxidation does not affect the initiation of vented water trees but it does affect the water tree growth rate. This is very important as it may result in significantly reduced times to breakdown in actual cables. Results of water tree tests performed in a nitrogen atmosphere are also presented. The initiation of vented water trees was not affected by the gas atmosphere, but the trees grew twice as fast as in air.<<ETX>>","PeriodicalId":184126,"journal":{"name":"Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115200465","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}

Acoustic probing consists of recording an electric signal generated by a charge or polarized sample under the action of a mechanical pulse causing a compression wave. The electrostriction method is based on recording an acoustic signal in the surface of an electrified sample which is affected by an electric pulse. Analysis shows that the two methods are equivalent as regards their physical basis and information provided. The fields of application of these two methods are shown to be somewhat different. Acoustic probing is more correct and technically simple when high-ohmic materials with a long charge relaxation time are under investigation. As an example, the study of diffusion in the nitric-acid-polyethylene system is considered.<<ETX>>","PeriodicalId":184126,"journal":{"name":"Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129596972","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}

Here they report the effect of this coating on the dielectric strength of high-density polyethylene. The polyethylene used is additive-free blown film with a density of 0.950 g/cm/sup 3/ and a melt flow rate of 0.9 g/10 min. The plasma-polymer coated sample studied is shown to have a higher breakdown strength than one without plasma-coating. The plasma-polymerized ethylene is amorphous, with many localized states in the forbidden band. These states act as trapping sites for electrons injected from the cathode. The trapped electrons, in turn, suppress the succeeding carrier injection from the cathode. The trapping centers seem to have an injection-suppressing effect even for the application of short-duration voltages such as impulse voltages. It is concluded that the suppression of electron injection by the coating brings about an increase in breakdown voltage.<<ETX>>","PeriodicalId":184126,"journal":{"name":"Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123557059","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}
