With increased focus on electrical safety and the widespread adoption by industry of NFPA-70E, infrared systems are increasingly becoming more popular. However, using infrared windows with thermal imaging cameras introduces a serious measurement accuracy problem when it comes to predictive maintenance. Current thermal imager technologies today can measure, with extreme degrees of accuracy, in the range of ± 5°C or better. However introducing any type of infrared window into a temperature measurement interjects measurement inaccuracies. This paper discusses the effects of various infrared window types on non-contact temperature measurement including the levels of inaccuracies created by alternative infrared window types, how to correct for these inaccuracies with various thermal imagers along with typical before and after accuracy results. The conclusions will provide methods for successfully using various thermal imagers along with various types of infrared window when combined within a preventive and predictive maintenance program.","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":"117000744","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}

Offline and online PD testing has become a widely used tool for infactory quality acceptance and a baseline performance evaluation of new groundwall insulation in stator windings rated 6 kV and above. Many petrochemical plants and refineries perform online PD tests to periodically assess the condition of the stator winding insulation on machines during operation. IEEE and the International Electrotechnical Commission (IEC) have created standards called recommended practices or technical specifications to address offline and online PD measurement using electrical diagnostic equipment, and optical measurement of surface PD. They explain testing objectives and principles, discuss commonly-used methods for measuring PD, and provide guidance for data interpretation. Users of these standards should identify the PD test method and acceptance criteria, as the standards describe several suitable test procedures, but provide no acceptance criteria. This paper provides an overview and comparison of the standards, and addresses some common questions about offline and online PD tests.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116107103","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}

[1] In that paper, system grounding and bus insulation were considered a means of reducing the probability of an arc flash incident by approximately two orders of magnitude. In September 2013, additional testing was conducted on a low voltage motor control center with the expectation that engineering enhancements such as insulated vertical bus, high resistance grounding, and other techniques, could be implemented to further reduce the probability of an arc flash incident. The testing performed was with faults initiated in locations typically found in operating petrochemical facilities, in low voltage motor control centers, with the starter unit door open. This paper discusses the findings of testing on real-world electrical equipment in an effort to further understand and minimize the probability of an arc flash incident. The paper reviews the physics of the arcing fault and how ignition wire, geometry, and the number of anode/cathode pairs all contribute to arcing fault energy and personnel exposure.","PeriodicalId":264800,"journal":{"name":"2014 IEEE Petroleum and Chemical Industry Technical Conference (PCIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122694099","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}
