Acoustic emission technique is advantageous for online PD measurement. PDs are classified according to the origin of discharges and their effects on insulation deterioration are also different. Acoustic emission (AE) signal produced by PD are detected by sensors mounted on the experimental tank surface, stored on an oscilloscope and fed to computer for analysis. PDAE signal propagates from source to sensor through oil and pressboard insulation. This paper discusses the effects of different thicknesses of pressboard insulation barrier on the propagation path of partial discharge acoustic emission signal. PD may occur at surface of insulation having different thickness at different voltages. This paper also discusses the effect of insulation thickness on surface discharge. The behavior of PDAE signal at different voltage level is also discussed. The AE signals are analyzed using FFT and DWT. The parameters calculated are frequency at peak magnitude & median frequency from FFT data and percentage signal energy in different frequency bands from DWT data. Effect of applied voltage beyond PD inception voltage is also examined. Acoustic PD magnitude (mV) and electrical PD magnitude (pC) relation for different electrode system is investigated.","PeriodicalId":429889,"journal":{"name":"2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129907239","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 contaminants can be produced by an abrasion between components during assembly or operations. These particles can either be free to move in the GIS bus or they may stick either to an energized electrode or to an insulator surface. In case a metallic particle crosses the gap and comes into contact with the inner electrode or if a metallic particle adheres to the inner conductor, the particle will act as a protrusion on the surface of the electrode. Consequently, voltage required for breakdown of the GIS may be significantly decreased. Diluted SF6/N2 mixtures could be a substitute to pure SF6 as insulation medium for high voltage gas insulated systems. They promise to have a lower environmental impact than a system insulated with pure SF6 for the same rating. The main issue concerning the practical use of such mixtures is their behavior in the presence of particle contamination. In this paper, particle movement is determined in both coated and uncoated gas insulated bus-duct (GIB) with Sulphur Hexafluoride (SF6) and Nitrogen (N2) gas mixtures as insulating medium on application of 175 kV switching impulse voltage. In the gas mixture, conducting particle material considered for this study is Copper and Aluminum.","PeriodicalId":429889,"journal":{"name":"2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128856771","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 tree multipliers have time complexity of O (log n) but are unsuitable for VLSI implementation since they require larger total routing length, which may degrade performance. The properties of simpler VLSI implementation can be combined with fully pipelined circuit design using CMOS TSPC (true single phase clock) logic design style to improve throughput of array multipliers. In this paper an improved high speed, fully pipelined 8times8 signed Baugh Wooley multiplier circuit has been designed and implemented using CMOS TSPC logic in 0.6 mum, N-well CMOS process (SCN_SUBM, lambda=0.3) of MOSIS utilizing optimized TSPC logic cells. The simulation results after parasitic extraction show that the inputs can be applied every clock and it can produce correct output after 17 clock cycles at 500 MHz clock rate. Thus the throughput of 500times106 multiplication per second is achieved using TSPC based fine grain pipelining. By designing and using novel TSPC full adder cell, our Baugh Wooley multiplier implementation shows large reduction in transistor count, average power and delay as compared to an implementation by Robert Rogenmoser and Qiuting Huang. The total transistor count, average power and maximum instantaneous power are indicated in comparison table.","PeriodicalId":429889,"journal":{"name":"2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126066903","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}
