Design of an appropriate electrical circuit, design of components, results obtained by simulation (on ORCAD-PSPICE) and experimental results obtained through bench-tests are presented. A set of button-type permanent magnet (total weight = 4 gm.) was considered as the object to be levitated and a coil-wound electromagnet used to create a magnetic force which opposed the weight of the object. Distance between the object and the electromagnet was measured using locally available Hall effect sensors and the output amplified using a locally available differential amplifier. Pulse Width Modulation was used to control the current required to generate the required electromagnetic force. The results show that even though the electromagnet was capable of levitating the object, maintaining perfect alignment of the CG of the object with respect to the centre of the electromagnetic force is an important issue. It is therefore suggested that a bar-magnet for the object and a horseshoe magnet for generating the required electromagnetic force would provide a solution. Further, since the model of a prototype can experience aerodynamic forces and moments along three axes, a satisfactory MAGLEV system requires use of multiple horseshoe magnets which can provide vectored electromagnetic forces to keep the object in force as well as moment equilibrium.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"19 1","pages":"441-444"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83789611","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}

An important function of AMS is the monitoring and diagnosis of the power transformers. Various tests are performed on power transformers to detect incipient faults. Among the available methods, Dissolved Gas Analysis (DGA) has been widely used and shown promise. However, interpreting the results of the DGA is challenging due to the availability of wide variety of methods such as Rogers ratio, Doernenburg ratio, key gas procedure of IEEE, Basic gas ratio and Duval triangle methods of IEC. The accuracy of the interpretation methods influences AMS performance leading to reliability issues in the grid. This investigation compares the accuracy of Duval method and basic gas ratio method to detect transformer faults from real-time fault data obtained from power transformers. Our results on data obtained from Electrical Research and Development Association for seven transformer incipient faults shows that the Duval method is accurate than the basic gas ratio method for identifying incipient transformer fault based on DGA results. Further, the basic gas ratio was not able to detect two of the seven faults. These results illustrate the need to integrate Duval method to detect power transformer faults within AMS.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"3 1","pages":"333-338"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73017947","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}
