Title: Study of the time-current characteristic of a high-power fuse in the limiting current region Keywords: High-power fuse, limiting current, thermal processesAbstract: This paper presents an experimental and numerical study of the thermal processes and time-current characteristic of a high-power low-voltage fuse. The tests within this study were carried out under rated current load and in the region of the limiting current. An experimental setup was developed for the purposes of the experimental tests. The temperature of the fuse was measured both by a thermovision camera and by a contact thermometer. The numerical studies were carried out by means of developed in COMSOL software 3D model of a fuse in transient mode. Results were obtained for the effect of the current load on fuse heating and actuation time. Comparison of the obtained experimental and numerical results was made. References - H. Farahani, M.
