The current wording covering the grease(s) qualifying for motors meeting this standard is spelled out in Section 6.1g of the Institute of Electrical and Electronic Engineers Standard 841; “Bearings shall be suitable for, and shipped with, rust-inhibiting grease compatible with polyurea-thickened grease.” There are two significant problems with this statement in today's operating environment: 1) how does one define compatible; and 2) these same polyurea-thickened greases have shortcomings that can be overcome by alternative grease technologies. In fact, polyurea thickeners are now broken into two performance categories, conventional and shear stable, and they may not be compatible with each other. Interestingly enough, some of these new grease technologies may well be compatible with the polyurea thickeners depending on the definition of that same troublesome word - compatible. The goal of this paper is to recommend improvements to update Section 6.1g by illustrating the issues with the above points so that both original equipment manufacturers and users can be confident that they are drawing maximum performance potential from their electric motors while providing flexibility to address significant specific end-use performance requirements.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126167792","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}

Motors constructed to API 541 standards are required to have a rotordynamic lateral natural frequency that is removed from the operating speed by at least 15%. The location of this natural frequency can depend on many factors such as bearing clearance, bearing type, residual unbalance, oil temperature, oil viscosity, and bearing housing stiffness. Depending on the design, some motors are more sensitive to these parameters than others, and small changes in these factors may cause large variances in the motor natural frequency. As a result, small variations in test setup, manufacturing tolerances, or field installations within critical components can cause noticeable differences between the calculated and measured natural frequencies. Variation in motor vibration may also be seen between the motor operating on the manufacturer's test stand and the motor operating in the field. In the field some apparently minor changes on ambient conditions or set up can significantly change the motor vibration. Additionally this paper will propose a worst case calculation method for motor natural frequencies that will provide greater confidence to the end user that the motor will operate successfully in the field before the motor is installed.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123335099","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}

Transient Recovery Voltages (TRV) that develop across the vacuum or SF6 interrupter contacts of the circuit breaker directly in series with the reactor during the interruption of reactor terminal faults can exceed TRV limits published for specific circuit breakers. This situation occurred in an Oil Sands application, where distribution system enhancements and expanded generation to meet process power and steam requirements resulted in overdutied medium voltage switchgear and required installation of a current limiting reactor. Using this case study from the Oil Sand application, this paper will examine transient program modeling techniques associated with reactor-limited fault current interruption and the subsequent TRV response that develops using electromagnetic transients program (EMTP) simulations. These TRV responses, subsequently, are compared to TRV envelopes established by harmonized IEC and IEEE Standards and, where available, manufacturer's breaker lab testing results. In limited cases where the standards or published limits are exceeded, as did occur in this Oil Sands case study, TRV-reduction techniques and the associated practical solutions will be examined. Such practical solutions discussed in the paper include the application of surge capacitors, RC snubber circuits or uprating the breaker to a higher voltage rating.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130699673","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 motor is now installed in power ranges between 3.5MW and 15MW and speed ranges between 13.500rpm and 4600rpm with both, Active Magnetic Bearings and Sleeve bearings. This paper will show the first time the complete range concept and the exact measured properties of this motor such as efficiency, power factor, noise date and vibration values as well as application and selection details for this High Speed Motor design. The Gearless High Speed concept offers opportunities in off shore application such as sufficient space and weight reduction for Platforms or FPSO vessels as well as advantages in reliability, availability and service compared to traditional geared solutions or turbine driven arrangements. The future design to meet these upcoming and promising applications will be discussed and introduced. This paper will continue the discussion on High Speed Motor applications in the PCIC forum and add a further step to increase possible applications in Oil & Gas.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126519892","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}
