Abstract of the project	The project is in the domain 3. Energy, Environment and Climate Change /Sub-domain 3.1. Energy. The project has a multidisciplinary theme and the main objective is the fault current interruption physics mechanism for the Direct Current (DC) fuses.  During the project it will be realized simulations regarding the switching having into attention: temperature distribution on the fuse-link element and on the assembly of the whole fuse; the electric arc type and the as fast as possible modalities to extinguish it; the current arc variation and voltage arc variation in the moment of the overloads interruption. The obtained results after the modelling and simulations in different operating conditions will be compared with the ones from the experimental tests for DC fuse with specified rated parameters. Some original and innovative aspects are also considered, such as: new thermal model of the DC fuse; new electric model for the DC fuse; new mathematical model for the DC electric arc; new experimental test bench with double supply for the DC fuse testing. By the common activities of the project new added values are considered, such as: new three-dimensional models for the temperature distribution inside the fuse-link and inside the whole volume of the fuse, improving of the fuse-link geometry, improving of the quality of the electric arc extinguishing fill material. New co-operations with the Chinese partner are also envisaged in the energy area.
