The focus on SPM in dispatching and emergency control systems is due to a number of factors, the most important of which is a sharp increase in the accuracy of measurements, since measurement non-synchronism is the main source of error in telemetry (TM).","PeriodicalId":345204,"journal":{"name":"2018 International Youth Scientific and Technical Conference Relay Protection and Automation (RPA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129826696","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}

Leading relay protection manufacturers have already successfully developed and launched production of microprocessor relay protection modules adapted to work with digital flows, using process buses according to Standard 61850-9-2LE. A somewhat more complicated task is the implementation of current and voltage instrument transformers. The simplest form is to use standard current and voltage transformers provided with measuring merging devices (Stand Alone Merging Units). This approach, however, does not fully resolve the problems of standard current and voltage transformers, such as core saturation. Because of their high price, the use of optical transformers is warranted only at voltages exceeding 110–220 kV. Using digital (unconventional) transformers opens the possibility of operating them in a wide voltage range, from 6 to 220 kV.","PeriodicalId":345204,"journal":{"name":"2018 International Youth Scientific and Technical Conference Relay Protection and Automation (RPA)","volume":"33 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132811318","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}
