Thus, to expand the ranges of impedance and frequency of the calibration system for ac shunt resistors, a current bridge method with cascaded current transformers (CTs) has been developed. An ac shunt resistor with nominal value of 10 mS was evaluated by a current bridge method using cascaded CTs, and the results of the calibration system using this method were validated. It was found that the calibration system for ac shunt resistors using the current-bridge method with cascaded CTs can be used successfully for both in-phase and quadrature components up to 3 kHz.","PeriodicalId":415488,"journal":{"name":"2016 Conference on Precision Electromagnetic Measurements (CPEM 2016)","volume":"310 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":"131855351","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 force measuring system and a mechanism providing vertical movements of the magnet are completely independent in an oscillating magnet watt balance.

We formulate the oscillating-magnet watt balance principle and establish the measurement procedure for the Planck constant.
