Such investigations on discs of compressed protein powders have revealed a wide range of electrical properties which have been studied as a function of hydration, hydrostatic pressure, NaCl content and deuterium-hydrogen exchange. These have been carried out using experimental techniques described elsewhere [1] that have been fully tested on more conventional elemental and molecular solids.","PeriodicalId":301436,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1982","volume":"442 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125763793","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 frequency acceleration of voltage endurance testing was reviewed and summarized in a recent IEEE symposium report [1]. While the intended purpose of such reviews is to evaluate the “state of the art” regarding a particular topic, they invariably raise additional questions for consideration. In this way, questions about the expected performance of magnet wire twist materials under variable frequency impulse stresses and about voltage aging of twists as a function of rectified half waves were brought up. The University of Connecticut, with the support and guidance of the Voltage Life Committee, has attempted to explore these questions as part of a summer program. Some results from this collaborative research are being reported in this paper.","PeriodicalId":301436,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1982","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125955999","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}

This model states that electrons and holes can be injected into the polymer from a metallic needle electrode either by tunneling via localized states or by thermionic emission, and that these injected charge carriers will form space charges which will then modify the electric field distribution and produce channels of lower density by mutual repulsion and dissociative recombination to create a favorable condition for impact ionization. These processes will lead to the formation of electrical trees. The present paper will present some new experimental results in support of this model.","PeriodicalId":301436,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1982","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127850168","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}

Due to the presence of water in the channels, the parallel phenomenon would be the so-called environmental stress-cracking (ESC); but, unlike ESC, the stress, originated from electrostatic pressure, would be directly exerted at the tips of the channels. The electric field being alternating, the phenomenon should be compared with fatigue ESC. A theoretical model for the propagation of a channel [1, 2], based on an energy criterion, has shown that in usual conditions the forces at the tip of a thin water-filled channel can cause fracture of the polymer. Other authors have also considered water treeing to be related to ESC [3]. Up to the present time, no convincing experimental proof for such an interpretation has been given.","PeriodicalId":301436,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1982","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116784578","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 space charges are closely related to defects, structure, and morphology. In the case of gaseous breakdown, space charge at the streamer tip gives rise to remarkably different behaviour of positive and negative streamers as was first pointed out by Von Hippel to explain Lichtenberg figures. Due to slower mobility & diffusion constant of positive carriers (ions, holes) than electrons in many dielectrics, the positive streamer tip retains a much higher field than the negative, resulting in much larger propagation velocity (106∼107cm/sec) in comparison with the negative streamer(105∼106 cm/sec). This may be also assisted by the photo ionization mechanism such as suggested by Loeb & Meek [2].","PeriodicalId":301436,"journal":{"name":"Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1982","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128788688","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}
