In this photo essay one company's experience will be shared. The first step, to define the mission, is the hardest. While development and quality control are suitable choices, one must take precedence. Second step is to study standard procedures from IEEE, NEMA and ASTM and to write a few procedures specifically for the lab. The lab used as an example specializes in development work on high voltage form wound coils. Described in order will be the layout of floor and wall space. The next item considered is the need for stationary furniture. This includes the work tables and lab benches. After the layout is complete then the primary equipment is bought. This list includes ovens, environmental chambers, and electrical test equipment. A list of useful small equipment is provided. This includes viscometers, balances, microscope and size measuring equipment. Finally for those labs with a luxury budget a few items are recommended. It is estimated that the basic lab can be built and equipped for $105,000.","PeriodicalId":148370,"journal":{"name":"1983 EIC 6th Electrical/Electronical Insulation Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131066249","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}

Various empirical criteria have been used to determine the Jevel of continuous applied voltage which could be considered a safe level for intended applications for these grades in service. To date, no significant quantitative studies have been made to relate the short time tests to actual long term capability of the coated sleeving. One obvious reason for this lies in the difficulty and cost of constructing test models that would possess reliable similarities to actual service. As an alternative, the authors present data obtained from short time breakdown testing in which the rate of voltage application is varied. By treatment of these data, using accepted mathematical relationships, a method of estimating the constant stress performance of the sleeving is developed. This method has promise for providing statistically significant data on lot-to-lot variability, effects of aging, modeling of service environments, etc.","PeriodicalId":148370,"journal":{"name":"1983 EIC 6th Electrical/Electronical Insulation Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133214243","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}

Accelerated aging was done on cable models with He, CF4, SF6, c-C4F8 and N2 gases dissolved in the oil. The aging was performed at 120°C with a voltage stress of 15 kv/mm and under a pressure of 238 kPa. The investigation included the observation of the dielectric losses variation with time, the measurement of the corona inception voltage, the ac breakdown of the samples as well as the detailed dissections of the cable models. The tests showed that the tracer gases other than helium performed at least as well as nitrogen, which has a long history of use in the field.","PeriodicalId":148370,"journal":{"name":"1983 EIC 6th Electrical/Electronical Insulation Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125201162","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 termination must also be at least equal to the cable insulation in resisting the high stresses of accelerated testing. Achieving this result is difficult since the testing program included the continuous use of high overstresses: electrical field up to 350 V/mil or 13.8 kV/mm (seven times normal), frequency up to 600 Hz (ten times normal), and conductor temperature up to 90 C. Heat-shrinkable, resistive-capacitive electrical stress relief is a low-cost terminating technique because of easy assembly and flexibility with respect to cable diameters and constructions. The electrical losses in standard stress control material in normal usage produce a temperature rise of less than 1 C. However, under the unusual test conditions employed, excessive localized temperature rise was observed. These temperatures were reduced by using a specially formulated material with reduced loss. Reasonably successful terminations were obtained for XLPE and EPR cables with the modified material when the stresses were as noted above. Terminating LDPE cables at the higher stresses still poses a problem, although it is possible that a major part of the problem with this material was the high conductor temperature.","PeriodicalId":148370,"journal":{"name":"1983 EIC 6th Electrical/Electronical Insulation Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127879799","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 performance of a stacked core depends upon among other things the type of core joint, the number of laminations in a group in core stacking, and the pressure applied to the core. A miter cut step lap core performed the best followed by a miter cut butt lap core, and then an I-plate core. The single phase I-plate core, which had a core loss of less than one third that of M-4 grade grain oriented silicon iron, was easier to stack than the miter cut cores.
