| Abstract: | The numerical analysis models for transformer no-load test and short circuit test are set up,in which the field-circuit coupled finite-element analysis is used.The electromagnetic field,in which situation the winding has strand-to-strand short circuit,is calculated.The computer em-ula tion re sults of judging strand-to-strand short cir cuits are giv en. |
