Effects of DC Magnetic Bias on the Magnetic and Sound Fields of Transformer ()
Abstract
DC bias current flowing into the neutral point of power
transformer will seriously affect the normal operation of AC power system. In
this paper, exciting current, harmonic component of the excitation current,
magnetic flux density and noise of transformer were analyzed when the transformer
is in the no-load operation state based on field-circuit coupled method.
Through the calculation and analysis, some reference bases are provided for design
of transformer.
