Transformer inrush is the most frequently encountered application problem. Its waveform is akin to that of a lamp-load inrush. However, contrary to a lamp-load inrush, the transient will not come to ...

A ferroresonant transformer is analyzed based on the equivalent magnetic circuit and then using magnetic-field equations. It is shown that the Fourier analysis provides a quick and reliable method for ...
