Tripathi, A.K.2026-02-052019Journal of Mines, Metals and Fuels, 2019, 67, 6, pp. 316-319222755https://idr.nitk.ac.in/handle/123456789/24519The paper describes the application method of symmetrical components for the analysis of unbalanced mine power distribution systems using B2-Spice. The knowledge of symmetrical components is extremely useful for the study of unsymmetrical faults in three-phase power networks. The concept is also useful for studying the three-phase machine behaviour under unbalanced conditions. B2-Spice is a general-purpose analog electrical and electronic circuit simulator. It is a powerful programme that is used to study the integrity of circuit designs and to predict circuit behaviour. © 2019, Books and Journals Private Ltd.
