Journal ArticleDOI
Dual Reversible Transformer Model for the Calculation of Low-Frequency Transients
TL;DR: In this paper, a physically consistent dual model for single-phase two-winding transformers for low-frequency transients is proposed. But the model remains invariant for all low-frequency transients including deep saturation conditions driven from any of the two windings.
Journal ArticleDOI
Elimination of Residual Flux in Transformers by the Application of an Alternating Polarity DC Voltage Source
TL;DR: In this paper, a new demagnetizer device with an alternating polarity dc voltage source is prototyped for transformers and applied to three-phase transformers with different core configurations and connections.
Journal ArticleDOI
An Online Data-Driven Technique for the Detection of Transformer Winding Deformations
TL;DR: In this article, a 3-D Lissajous curve method with a Butterworth low-pass filter is used to identify changes in the short-circuit impedance of two-winding single-phase transformers.
Journal ArticleDOI
Retrofitting the BCTRAN Transformer Model With Nonlinear Magnetizing Branches for the Accurate Study of Low-Frequency Deep Saturating Transients
TL;DR: An extension to the multiwinding BCTRAN model is proposed for the study of low-frequency saturating transients in single-phase transformers and the results show that the simulations and experimental results match very closely giving great confidence in the model correctness and parameter estimation method.
Journal ArticleDOI
Mitigation of Half-Cycle Saturation of Adjacent Transformers During HVDC Monopolar Operation—Part II: Detecting Zero-Sequence Fault Currents
TL;DR: In this article, a neutral current blocking switch is proposed to mitigate half-cycle saturation of transformers caused by monopolar operation of neighboring HVDC transmission lines while keeping the ability to detect the zero-sequence fault currents (ZSFC) when ground faults occur.
