Improved low voltage (LV) and medium voltage (MV) control equipment designs, including enhanced structural protection systems, have continued to evolve in support of improved personnel protection. The requirements for employee safe work practices have all targeted reducing the risks of electrical arc hazards. However, arcs accompanied by explosions continue to occur in electrical systems. Factors such as inappropriate human interaction with the equipment, equipment malfunctions because of misuse or lack of regular maintenance or unforeseen events continue to contribute to the unexpected release of explosive electrical energy in the workplace. New arc resistant LV and MV control equipment designs provide an additional level of protection if properly installed and applied. This paper will outline the added benefits of properly applied arc resistant equipment along with the details surrounding the appropriate installation and site application considerations when arc resistant control products are being considered for inclusion in forest product industry production facilities.","PeriodicalId":217420,"journal":{"name":"Conference Record of 2009 Annual Pulp and Paper Industry Technical Conference","volume":"7 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116859909","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 law mandates upgraded electric motor efficiency beginning in 2010. Canada is expected to follow with a similar requirement beginning January 2011. Other countries are also mandating MEPS (Minimum Efficiency Performance Standards) for electric motors. In response to a need for leadership in the international motor efficiency arena, the National Electrical Manufacturers Association (NEMA) has responded by creating a new NEMA Premium® standard for the 50 Hz market. This paper will discuss the benefits of global NEMA efficiency standards and how end-users can now specify NEMA Premium motors as components of equipment built for use on their 50 Hz grid. The standard builds on the already highly accepted 60Hz standard that was established in 2001. The paper will include performance, test and construction considerations that were necessary to optimize motor features and efficiency in a 50 Hz application. This paper will also provide a status of NEMA Premium sales in the previous four years and joint activities with the Standards for Energy Efficiency of Electric Motor Systems (SEEEM) initiative.","PeriodicalId":217420,"journal":{"name":"Conference Record of 2009 Annual Pulp and Paper Industry Technical Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127799573","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 require operator contact between each set of rolls, for threading, re-filling the unwind stand and inserting cores. New winders are fully automated with designed-in safeguards. However, most operating winders are legacy machines requiring much manual intervention and do not have as many designed-in safety devices as new machines. The winder is usually the first job for entry level operators. Because of the frequent exposure to hazards, and the newness of the operators, injuries are more likely at the winders and roll finishing than in other paper mill areas. In addition to many different winder designs and vintages, mills have independently developed approaches to address these hazards which are not always coordinated among mills. This paper describes an enterprise wide approach for addressing winder safety. Roll finishing safety will not be included in this paper.","PeriodicalId":217420,"journal":{"name":"Conference Record of 2009 Annual Pulp and Paper Industry Technical Conference","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114607151","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}

DC motor speed is easily controlled by varying the supplied armature voltage and/or excitation (field) current. Many mills have inquired about operating motors beyond the original motor rating. With armature voltage limited by the drive, motor speed may be increased by reducing the shunt field current, but not without consideration of vibration, machine adjustment, brush performance, and possible commutation issues because the machine was not designed and tested at those conditions. This paper examines and presents test/field data displaying the effects of field weakening on DC machine performance and maintenance.","PeriodicalId":217420,"journal":{"name":"Conference Record of 2009 Annual Pulp and Paper Industry Technical Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129871845","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}

Common misconceptions and system application issues regarding these devices will be discussed. Several examples of on-line infrared scans of circuit breakers over the course of a five year period will be presented and reviewed. Experiences at an integrated paper mill located in Longview, Washington USA explains documented cases where infrared thermography has been used as a predictive maintenance tool in determining potential problems with breakers while in service. Follow-up analysis by the circuit breaker manufacturer has generally validated mill maintenance decisions to remove a breaker from service and replace it, based on infrared scan results. Periodic infrared scanning used as a tool in identifying potential problems with sealed molded case circuit breakers will be discussed. This and other breaker off-line testing methods used at this site will be reviewed. Finally, overall reliability improvement and impact on the results of the existing mill-wide safety compliance programs will be summarized.","PeriodicalId":217420,"journal":{"name":"Conference Record of 2009 Annual Pulp and Paper Industry Technical Conference","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126771265","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}
