| Abstract: | Large current transformers are mainly used in large scale generators. Its stability and reliability will influence the securit y of the whole electric power system, so the research to the stability of large current transformers is important. The paper analyzes the current of shielding w indings and its optimal design for three-phase 15000/5A current transformers ba sed on ANSYS. The simulation results demonstrate that the two methods of paralle l connecting 4 shielding windings and reversed polarity series connecting two pa irs of shielding windings are better. |
