Thermal behaviour of a transformer mineral oil‐tank surface under incipient turn‐to‐turn short‐circuit fault

IET Science, Measurement & Technology
A slight turn‐to‐turn short‐circuit fault in the incipient stage does not trigger fuse protection, and the regular transmission and transformation functions of the transformer within the power grid are not affected very much by the incipient turn‐to‐turn
