T he current ntroduc ng met hod of s nglephase synt het c test w as adopted by t hreephase sy nt het c t est t o real ze t hreephase current parallel nt roduc ng. T he s mulat on model of t hreephase sy nt het c t est was performed us ng t he commerc al sof tw are MAT LAB/ SIMU L IN K . T he s mulat on results w ere f urther analyzed. F rom t he s m ulat on results, t can be seen that the t est equ valence s related to the trans ent recovery volt ages of f rst break ng pole, t w o last break ng poles, and the t me of shunt current nt roduc ng.
