| Abstract: | This paper simply stated the principle of sympathetic inrush, and created the parallel transformer sympathetic inrush model in PSCAD. This paper analyzed the characteristics of transformer sympathetic inrush and harmonic current by simulation, gave the causes of zero-sequence current and its harmonic current component in transformer neutral directly grounded system at the same time, and pointed out the effects on relay protection |
