Unlike many publications on the same topic, this research has been conducted with real synchrophasor archives collected from three 500 kV lines in the Russian power grid during four different single line-to-ground faults. We have analyzed quite a few well-known fault location expressions in an unusual scenario of taking in current and voltage data from phasor measurement units, all configured as M class devices according to IEEE C37.118. The main outcome of the obtained numerical data is that the fault location error of less than 1 % was achieved in all of the examined practical scenarios, often by a few fault location expressions at once. This is despite having long enough M class filters and utilizing current signals from measuring transformers that could saturate during a fault. The results are therefore valuable for future synchrophasor application roadmaps.","PeriodicalId":343971,"journal":{"name":"2021 4th International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124528537","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}

Failure mode, effects and criticality analysis of asynchronous motors shows that most of them are associated with insulation faults, deterioration of contact connections and short circuits. The most common type of malfunction in asynchronous motors is phase-to-phase and inter-turn closure. Insufficient sensitivity leads to significant failure to their windings, overspending of the winding material, and an increase in the time and cost of post-emergency repairs. Thus, the research and development of new relay protection devices with increased reliability for auxiliary mechanisms with asynchronous motors is an urgent task. Therefore, in this work, the most relevant method of using of microprocessor devices for protecting asynchronous motors between phases and turn-to-turn short-circuit is considered in order to substantiate the need to expand the capabilities of protection systems and diagnostics of an asynchronous motor. Several models of microprocessor devices are presented that can be applied to a particular issue with good accuracy. At the end there is a table for easy comparison of the characteristics of various models of microprocessor devices, relay protection and automation. This table shows a comparison of the protection and automation functionality.","PeriodicalId":343971,"journal":{"name":"2021 4th International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123252001","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}
