The scope includes three-phase premium efficiency severe duty TEFC squirrel-cage induction motors with antifriction bearings in sizes up to and including 370 kW (500 hp). In addition to motor rated voltages of 200 V, 230 V, 460 V, 575 V, 2300 V and 4000 V at 60 Hertz; 230 V, 400 V, 690 V and 3300 V at 50 Hertz are now included. Changes to the standard are reviewed in detail. Requirements are identified that improve motor reliability and increase motor life.","PeriodicalId":182346,"journal":{"name":"Conference Record of 2010 Annual Pulp & Paper Industry Technical Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121706654","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}

Typically, this bus arrangement is in a main-tie-main arrangement. Upon the loss of the normal power source, critical motor loads must be transferred to the alternate source without damaging the equipment, and ideally, without interrupting the process. In this application, two digital motor bus transfer systems were installed to transfer two 4 KV busses to two sources. This paper describes the steps to applying a digital motor bus transfer system to medium-voltage switchgear at a large chemical company including the feasibility analysis, available transfer methods, input/output considerations, settings, and commissioning methods. A summary of actual operations data to date and lessons learned is also included.","PeriodicalId":182346,"journal":{"name":"Conference Record of 2010 Annual Pulp & Paper Industry Technical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122510192","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}
