Investigation of magnetizing inrush current in transformers. II. Harmonic analysis

摘要

For pt.I see ibid., vol.8, no.1, p.246-54. Simulation data for the magnetizing inrush current generated by power transformers, obtained in part one, are used for harmonic analysis. The simulation results show very good agreement with experiment results. The relationship of the harmonics to all parameters is discussed. The results establish a guideline for eliminating harmonics due to inrush current, and provide reference for system design.
