This paper researches the fusing problem of the generator voltage transformer primary fuse on normal opera-tion,analyses the event developing process,and derives the direct reson is the long-term firing in the gap of the broken fuse,proposes the measures to choose the generator voltage transformer fuse with porcelain core and add paralleling volt-age comparator to the voltage failure logic in the excitation system.
