“…In every contact junction there is the same power loss P 0x and along the small fuselinks there is the axial heat flux of P x = P 0x /2. The small fuselinks are actually conductors with the constant cross-sections and in this case, the power balance in steady-state conditions can be considered as [12,32]:…”

In many industrial applications high breaking capacity (HBC) fuses are used to protect electrical installations against overcurrents, especially in the power distribution network. At high rated current, HBC fuses have more parallel fuselinks mounted inside. The technological and mounting processes of the fuselinks inside the fuse results in an asymmetrical current distribution through the parallel fuselinks. In this article a model of a high breaking capacity fuse using two parallel fuselinks is proposed. The influence of electric current, cross-section of the notches, distance between notches and current imbalance through fuselinks on the maximum temperature rise of both fuselinks, has been investigated. Also, a 3D thermal model for the same HBC fuse has been developed. The temperature spread into the fuse and its elements has been obtained. In order to prove the validity of the mathematical and 3D model different tests have been considered. The experimental, simulation and computed results give similar values and it results that this model can also be used for fuses with many parallel fuselinks and it permits the design of new fuse elements with optimal thermal distribution.

“…Moreover, the fault current may cause an abnormal operation of transformers and sensitive loads, and results in lower power quality [1][2][3][4]. Various approaches have been proposed for limiting the fault current and preventing the insulation failure problems, such as employing single-use fuse [5][6][7], series current limiting reactor [8], series transformer [9], and also superconductive limiter [10][11][12]. These solutions may cause other problems such as series resonance, need for an additional control circuit, and more power losses during the steady state operation mode, and complexity of control strategy.…”

Summary This paper proposes a new concept for limiting fault current in distribution systems with interline bridge‐type fault current limiter (IBFCL). It includes two or more BFCLs connected to only a common limiting resistor in DC link, which result in considerable cost saving. This configuration is inserted in series with feeders connected to a point common coupling (PCC). At first, the principle and characteristics of IBFCL are described. Then, a theoretical analysis of limiting performance and parameter design of the IBFCL is explained. Finally, the performance of the IBFCL for limiting fault current is validated on the distribution system comprising of parallel feeders connected to PCC through electromagnetic simulations by PSCAD/EMTDC under symmetrical and asymmetrical faults as well as different load current conditions. Simulation results show that the IBFCL provides a cost‐effective approach for limiting fault current in distribution system.
