Harmonic performance of single phase transformer with DC biased
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Direct current (DC) flowing through the earthed neutrals of transformer windings causes a DC component in magnetizing current. Owing to nonlinearity, the waveform of this current is strongly distorted. A high enough ...
Harmonic content as the indicator of transformer core saturation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
The paper proposes a measurement method for obtaining the parameters needed to calculate a reliable indicator of the state of transformer core saturation. The major nonlinear effects in transformer core are saturation, ...
