| Abstract: | This paper demonstrates the reason for virtual grounding caused by ferroresonance,analyzes the mechanism of bus bar ferroresonance and virtual grounding from the characteristics of resonance and single-phase grounding,of which the similarities and differences are distinguished as well,points out the disadvantage of ferroresonance and proposes the prevention and measurement of ferroresonance which are proved effective examples. |
