Time-frequency analysis of DC bias vibration of transformer core on the basis of Hilbert–Huang transform
This paper presents a time–frequency analysis of the vibration of transformer under direct current (DC) bias through Hilbert–Huang transform (HHT). First, the theory of DC bias for the transformer was analyzed. Next, the ...Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e Investigación. 2016-01-01
