The zero-sequence current transformer, specifically designed for measuring unbalanced phase currents, offers advantages in measurement range, identity, and size, compared to using three separate current transformers. However, it cannot provide detailed information on the unbalance status beyond the total zero-sequence current. We present a novel method for identifying unbalanced phase currents based on phase difference detection using magnetic sensors. Our approach relies on analyzing phase difference data from two orthogonal magnetic field components generated by three-phase currents, as opposed to the amplitude data used in previous methods. This enables the differentiation of unbalance types (amplitude unbalance and phase unbalance) through specific criteria and allows for the simultaneous selection of an unbalanced phase current in the three-phase currents. In this method, the amplitude measurement range of magnetic sensors is no longer a critical factor, allowing for an easily attainable wide identification range for current line loads. This approach offers a new avenue for unbalanced phase current identification in power systems.<\/jats:p>","DOI":"10.3390\/s23125654","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T10:19:22Z","timestamp":1686910762000},"page":"5654","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Unbalanced Current Identification of Three-Core Power Cables Based on Phase Detection of Magnetic Fields"],"prefix":"10.3390","volume":"23","author":[{"given":"Shangqing","family":"Liang","sequence":"first","affiliation":[{"name":"College of Electronics and Information, Hangzhou Dianzi University, Hangzhou 310018, China"},{"name":"Ocean Technology and Equipment Research Center, Hangzhou Dianzi University, Hangzhou 310018, China"}]},{"given":"Mingchao","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Electronics and Information, Hangzhou Dianzi University, Hangzhou 310018, China"}]},{"given":"Guoqing","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Electronics and Information, Hangzhou Dianzi University, Hangzhou 310018, China"},{"name":"Ocean Technology and Equipment Research Center, Hangzhou Dianzi University, Hangzhou 310018, China"}]},{"given":"Lin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Electronics and Information, Hangzhou Dianzi University, Hangzhou 310018, China"}]},{"given":"Xiong","family":"Cai","sequence":"additional","affiliation":[{"name":"Daishan County Electric Power Supply Branch of State Grid Zhejiang Electric Power Co., Ltd., Zhoushan 316200, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6373-3883","authenticated-orcid":false,"given":"Yuanguo","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Communication and Information Engineering, Xi\u2019an University of Science and Technology, Xi\u2019an 710054, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Abdel-Akher, M., Nor, K.M., and Abdul-Rashid, A.H.
