Abstract Based on the phenomenon of “slow melting” phenomenon of PT high-voltage side fuse in a factory, this paper analyzes the cause of “slow melting” phenomenon and the influence of “slow melting” on excitation system, generator protection and measurement system in detail, puts forward the judgment method of “slow melting” phenomenon of high-voltage side fuse, and sums up three methods to solve “slow melting” of PT high-voltage fuse at the end of the generator.
