Typical VFD internal motor protection functions are reviewed to understand the required roles of external motor protection relays. Applications discussed include protection requirements when the relay is located on the source side of the VFD and the motor side of the VFD. The impact of using a bypass switch around the VFD on protection requirements is also discussed.","PeriodicalId":118880,"journal":{"name":"2015 61st IEEE Pulp and Paper Industry Conference (PPIC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116407532","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 paper provides a summary the research surrounding the development and testing of new advanced sensor technologies for this purpose. More extensive and detailed measurements, regarding significant defects leading to an arc flash event, have been completed since the first portion of the research was completed [1]. Early detection of impending faults and the prediction of future arc-flash occurrences in medium voltage (MV) switchgear and motor control centers (MCC) can be very beneficial. The development of new sensor technologies, both for partial discharge (PD) measurement and thermal detection, are discussed and evaluated. The two most common non-contact causes leading to an arc-flash event in MV switchgear and MCC are insulation degradation and thermal stresses. This paper will highlight very detailed results measured under both of these conditions in the laboratory and actual installed conditions. An effective signal processing method, used for extracting the essential indication data and the integration of this system into an existing protection PLC or SCADA, are outlined.","PeriodicalId":118880,"journal":{"name":"2015 61st IEEE Pulp and Paper Industry Conference (PPIC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123361414","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}
