The investigation involves the variation of power loss, building factor, the third harmonic distortion and flux leakages. The power loss and flux distribution have been measured using no load test in two types of model of setting of core built from the same size and type of M5 (CGO) grades material of laminations. And the loss of the transformer core without air gap of layer joint of core lamination is 2.75% better than the loss of the transformer core with air gap of layer joint of core lamination at 1.7 T, 50 Hz. The flux leakage at the corner joint in the core without air gap of layer joint of lamination is lower than that in the transformer core with air gap of layer joint of lamination, over the whole flux density range. The third harmonic distortion of flux is smaller in the transformer core without air gap of layer joint of lamination and larger in the transformer core with air gap of layer joint of core lamination. Using the type without air gap of layer joint of lamination in transformer core is more efficient than the other types of transformer core lamination.","PeriodicalId":356424,"journal":{"name":"2007 Asia-Pacific Conference on Applied Electromagnetics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132862960","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}

They have to speculatively and periodically check their mailbox contents. In most events, the users are neglectful on checking their mailbox. This at times may lead towards the ignorance of important letters and results in various miseries. Most of the multi story buildings such as apartments, condominiums, office buildings etc limit the users on limited visits to check or collect their letters due to the centralize mailbox location. Users find convenient to be on alert of mails they receive to overwrite the conventional method of checking mailbox. Because of the high confidentiality and official letters are increasing as a corresponding tool globally, the users seek for a better solution which enables them to be on their toes each time a mail is delivered. The state of the art electronics technology is incorporated into these conventional mailboxes as a solution. The programmable logic controller, interface module and the GSM modem can be incorporated by linking the userpsilas mailbox with short messaging system or email facilities and this enables the users to be notified whenever a new mail is delivered. Mails delivered into the users mailbox, the system will automatically generate an alert which is send in the form of a short message system or email that typically details the real time of mail delivery. The system is designed to easy human life by sending short messaging system or email to notify the users about important new mails reaching their mailbox. This is likely to be a fast growing and popular application for short messaging system and email towards the mankind.","PeriodicalId":356424,"journal":{"name":"2007 Asia-Pacific Conference on Applied Electromagnetics","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114501483","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}
