A novel methodology for transformer low-frequency model parameters identification (original) (raw)

2013, International Journal of Electrical Power & Energy Systems

This paper describes a novel methodology to estimate the parameters of a low-frequency model of a 3-phase transformer, by only using data from its frequency response. The described calculation procedure takes into account the magnetic coupling among different phases and allows their analysis separately, enabling the identification of a possible failure. This work describes the used core model, the procedure to obtain its parameters, and its application when interpreting the low frequency results of the Frequency Response Analysis (FRA) measurements.
