Comparison Between the Measured and Model-Calculated Temperature of the LV Melting Fuse
Authors: , , ,
Abstract: Electric fuses are being used for over a century. They are an important factor for protection of electric power systems and apparatuses. This article describes a low voltage melting fuse. The authors used a numerical and real model of the fuse. The numerical model is composed of the finite elements and includes electric and temperature characteristics of a material and boundary condition values. The numerical model is formed as a 3D fuse model. The real model represents a fuse, on which were fixed thermoelements to measure the temperature in laboratory surroundings. The measurements were made under nominal current (400 A) and under half of the nominal current (200 A). This paper compares the measured temperature with the calculated, acquired by the simulation model of the fuse.
