Description
Summary:This paper describes a fuse model that can calculate the fuse current and voltage fluctuations from the start of a shorting accident to the completion of the fuse blowing. In the previous paper, the melting time and fuse current were calculated by considering the detector's current and diffusion factor during the melting period. Here, we extend the model to calculate the arcing time. Our model has a capacitor model that can represent the level of voltage fluctuation and waveforms of decreasing current. It also has an arc switch that can represent the voltage drop when the fuse becomes completely isolated from the circuit. Simulation results are in good agreement with the experimental results. We can calculate these characteristics easily, automatically, and accurately. Once we have obtained the fuse blowing parameters by performing only one experiment, we can calculate these characteristics even if the system is changed.
