Compared the calculated curve and the real assay curve we can make a conclusion that: this method can calculate the melting time of the fuse at the huge short current (more than 50 times of the current rating) with the error less than 5%; the resistor and time characteristic can also be acquired, it provided the date for overvoltage calculation of the fuse model. The research of the overvoltage during fusing process is based on short circuit test of the fuse.
