It is also one of the toughest concepts for many transformer Engineers to understand. The elusiveness of the concept originates because transformer designers are predominantly Electrical Engineers and most of the skills needed to evaluate temperature rise are mechanical in nature. This paper will discuss the major modes of thermal transfer in self-cooled coils. Models will be developed and procedures explained to apply these techniques to numerous core and coil geometries. The models in this paper can be applied to a broad size range of units from small PC board mount all the way in excess of 5000 KVA. The author has used these methods to predict temperature rise in units as small as a 1/2\" cube, as large in diameter as 84\" and as long as 48\"","PeriodicalId":267510,"journal":{"name":"Proceedings Electrical Insulation Conference and Electrical Manufacturing Expo, 2005.","volume":"46 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":"126126913","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 magnetic field associated with this primary current propagates as a wave and can couple into the secondary circuit; however, it moves as a diffusion front through the core material. Modeling of the diffusion of the magnetic field through the core determined that it affects the magnitude and time signature of the voltage induced in the secondary winding when the primary current is produced by a capacitor discharge. During the quarter cycle rise time (227 ns) of the current pulse in the primary, a step response to an incident magnetic field would yield 95.57 percent of the steady state magnetic flux. Since the voltage induced in the CVT secondary is proportional to the time derivative of the magnetic flux, time delay would further distort the CVT current measurement","PeriodicalId":267510,"journal":{"name":"Proceedings Electrical Insulation Conference and Electrical Manufacturing Expo, 2005.","volume":"120 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":"124165515","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 can be realized in an advantageous way with combinatorial sensors, an antenna sensor, a UHF sensor, and two VHF split-core PD sensors. These sensors are not connected to the high voltage directly, a UHF sensor can be placed near the cable joint and two split-core sensors can be installed on both sides of the cable joint easily and safely. The detection making several windows in the time domain towards multiple wide-band pulse signals can achieve reliable discrimination of real internal PD and external noise under noisy on site conditions. More than twenty cases of on-site PD detection for HV XLPE cables have been proven this way. This method has high detection sensitivity and high noise recognition ability","PeriodicalId":267510,"journal":{"name":"Proceedings Electrical Insulation Conference and Electrical Manufacturing Expo, 2005.","volume":"41 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":"122796154","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}

Processes such as optical lithography, X-ray lithography, LiGA, selective laser sintering, laser micromachining, wet and dry plasma etching, casting, molding etc are already well established. However, newly emerging processes such as laser nanofabrication, atomic force microscopy, dip pen nanolithography, diamond nanogrinding etc, have yet to realize their potential. The future of micro and nanomanufacturing lies in the ability to convert micro and nanofabrication techniques into mass production manufacturing processes where small-scale products can be economically manufactured in a short period of time. This may be achieved by combining micro and nanoscale processes, or by combining 'top down' and 'bottom up' manufacturing techniques. The development of so-called hybrid manufacturing processes is set to take center stage in the future development of micro and nanomanufacturing processes.
