First, the mutual inductance between the discrete RC and circular and rectangular conductors are calculated using the magnetic vector potential (MVP) method. The results are found to be consistent with those calculated using the finite element method, but the MVP method is simpler and more practical. Then, the influence of conductor section parameters, inclination, and eccentricity on the accuracy of the discrete RC is calculated to provide a reference. Studying the influence of an external current on the discrete RC\u2019s interference error reveals optimal values for length, winding density, and position arrangement of the solenoids. It has also found that eccentricity and interference errors decreasing with increasing number of solenoids. Finally, a discrete RC prototype is devised and manufactured. The experimental results show consistent output characteristics, with the calculated sensitivity and mutual inductance of the discrete RC being very close to the experimental results. The influence of an external conductor on the measurement of the discrete RC is analyzed experimentally, and the results show that interference from an external current decreases with increasing distance between the external and measured conductors.<\/jats:p>","DOI":"10.3390\/s18030847","type":"journal-article","created":{"date-parts":[[2018,3,13]],"date-time":"2018-03-13T13:37:21Z","timestamp":1520948241000},"page":"847","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Research on the Factors Influencing the Measurement Errors of the Discrete Rogowski Coil"],"prefix":"10.3390","volume":"18","author":[{"given":"Mengyuan","family":"Xu","sequence":"first","affiliation":[]},{"given":"Jing","family":"Yan","sequence":"additional","affiliation":[]},{"given":"Yingsan","family":"Geng","sequence":"additional","affiliation":[]},{"given":"Kun","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Chao","family":"Sun","sequence":"additional","affiliation":[]}],"member":"1968","published-online":{"date-parts":[[2018,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"354","DOI":"10.1109\/JSEN.2009.2013914","article-title":"Current Sensing Techniques: A Review","volume":"9","author":"Ziegler","year":"2009","journal-title":"IEEE Sens.
