For the past decade, many researchers have tried to improve the treeing-retarding properties of this material. Despite the many avenues of research, a more complete understanding of the retardation process is needed. The purpose of this paper is to report results on the effectiveness of several organic compounds as additives to prevent treeing propagation.","PeriodicalId":354533,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1986","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131861909","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 PD pulses occur in presence of UV radiation and appropriate value of current limiting resistance.

It is possible to distinguish the PD pulses produced due to partially developed avalanches, rough surface and due to dust or metallic particles. A possible method of confirmation of cleanliness of electrode surface after mounting them in the cell is suggested.","PeriodicalId":354533,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1986","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126982227","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}

We show that the behavior of such systems may be understood by assuming that the reaction rate in the electrochemical cell is controlled by the (polymer) electrolyte resistance. From this, experimentally observed variations of voltage with temperature and with polymer thickness can easily be explained. In these systems one observes that open-circuit voltages under vacuum and under atmosphere are significantly different. We have studied the influence of a number of gases and find that water vapor is responsible for this effect. We present a semi-empirical model to describe this dependence.","PeriodicalId":354533,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1986","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126132888","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}

They have been tentatively described by a wide variety of theoretical models. Although these theories partially describe actual experiments, they rarely give a complete and unequivocal explanation of the observed phenomena. One objective of this paper is to make a critical review (relying on existing data) of some often used models and also to point out their limits of validity. It will be shown that many results cannot be described by a given model either because the basic requirements of this model are not fulfilled or either, because another theory would give a much better fit to experimental results. Another objective is to briefly discuss the nature of charge carriers in polymer dielectrics. Ionic measurements obtained with recently developed ion chromatographs are presented and discussed.","PeriodicalId":354533,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1986","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116797178","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 damage process depends very much on the way the system reacts to the local field enhancement. To make this point clear we discuss a simple example. We consider a simple needle-plate geometry. We furthermore assume that the current density versus local field relation exhibits an instability. The physical origin of this instability is not of interest in our context. This gives us the possibility of dividing the current density versus local field relation into three regimes: I linear, low field, II nonlinear, positive differential conductivity, high field, III negative differential conductivity (NDC). Region I is of no interest in connection with defect induced breakdown and ageing.","PeriodicalId":354533,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1986","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134255028","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}
