We describe preliminary results obtained in tests of waveform synthesis with pulse-driven Josephson arrays fabricated at PTB. Unipolar sinewaves at 1.25 kHz and amplitudes ranging up to tens of millivolts were generated. Results are then discussed in relation with the specific thermal issues posed by He-free cooling.","PeriodicalId":415488,"journal":{"name":"2016 Conference on Precision Electromagnetic Measurements (CPEM 2016)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126415635","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}

A technique is proposed for real-time measurement of simultaneous deviations of frequency and amplitude of a voltage signal that it is feasible for measuring in a given node in a power system. Knowledge of the instantaneous value of the amplitude and frequency in a power system provides an enhanced capability for monitoring of dynamic failures of the system allowing taking corrective actions from their inception.","PeriodicalId":415488,"journal":{"name":"2016 Conference on Precision Electromagnetic Measurements (CPEM 2016)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129872715","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}
