Design of protective systems in large power transformers necessitates a detailed knowledge of the magnitude and shape of the magnetising inrush current during the switching operation. It is very difficult to evaluate the inrush current analytically owing to nonlinearity in the magnetisation (B-H) cu
## Abstract When a transformer is connected to a circuit, under certain conditions, magnetizing inrush currents may be about ten times the full load current of the transformer. The currents contain a large amount of harmonic components and cause some relays to trip out. In this paper, the magnetizi
