It is of great value to diagnose faults using the large amount of power data generated by the grid. It is possible to detect internal latent faults in transformers in advance of their occurrence if the normal operating condition of the transformer is detected in a timely manner. To perform online fault diagnosis of grid current transformers, we combine the Transformer and BiGRU methods. There is a temporal component to the fault input sample sequences. By using Transformer\u2019s multi-headed attention mechanism to extract deep features from fault input sample sequences, the temporal association between latent variables can be fully exploited. As a result of the extraction of features, BiGRU is used to generate fault category coding as an output. The experimental results indicate that using the proposed algorithm achieves better results than using a single model, which is useful for the study and application of fault diagnosis in power grids for current transformers.<\/jats:p>","DOI":"10.3233\/jcm-226763","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T12:31:14Z","timestamp":1682685074000},"page":"1137-1149","source":"Crossref","is-referenced-by-count":3,"title":["Research on online monitoring of grid current transformer based on transformers and BiGRU"],"prefix":"10.66113","volume":"23","author":[{"given":"Xiaokui","family":"Zang","sequence":"first","affiliation":[]},{"given":"Zhiqiang","family":"Cao","sequence":"additional","affiliation":[]},{"given":"Mengshi","family":"Xiao","sequence":"additional","affiliation":[]},{"given":"Xiaoou","family":"Yang","sequence":"additional","affiliation":[]}],"member":"55691","reference":[{"issue":"49","key":"10.3233\/JCM-226763_ref1","first-page":"1","article-title":"Single-phase ground fault selection method for small current grounding system based on compensation parameters","volume":"2","author":"Guojun","year":"2021","journal-title":"Power System Protection and Control."},{"key":"10.3233\/JCM-226763_ref2","unstructured":"Wenxia S, Hui W, Ming Y, Yuan Z, Daixiao P, Xiang S.
