The DC component in the measured current can saturate the transformer and cause gross error. We use fluxgate detection and digital feedback compensation of the DC flux to suppress the overall error to 0.15%. This concept can be used not only for high-end CTs with a nanocrystalline core, but it also works for low-cost CTs with FeSi cores. The method described here allows simultaneous measurements of the DC current component.<\/jats:p>","DOI":"10.3390\/s16010114","type":"journal-article","created":{"date-parts":[[2016,1,20]],"date-time":"2016-01-20T11:19:41Z","timestamp":1453288781000},"page":"114","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["DC-Compensated Current Transformer"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1115-6265","authenticated-orcid":false,"given":"Pavel","family":"Ripka","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering, Czech Technical University, Technicka 2, 166 27 Praha 6, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karel","family":"Draxler","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Czech Technical University, Technicka 2, 166 27 Praha 6, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renata","family":"Stybl\u00edkov\u00e1","sequence":"additional","affiliation":[{"name":"Czech Metrology Institute, V Botanice 4, 150 72 Praha 5, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,1,20]]},"reference":[{"key":"ref_1","first-page":"1078","article-title":"Current Transformer and Relay Performance in the Presence of Geomagnetically-Induced Currents","volume":"100","author":"Kappenman","year":"1961","journal-title":"IEEE Trans.
