Nowadays, the complexity of electrical power systems is increasing. Consequently, the occurrence and the amplitude of the fault current are rising. This fault currents harm the substations’ electrical equipment. Besides, the growth in the fault current level is forcing the change of the circuit breakers to others with a higher interruption capability. A proposal to solve this problem is the fault current limiter (FCL). This equipment has low impedance in the normal operation and high impedance in a short circuit moment. Superconductors are an advantageous choice of material in this case, because of their properties. In order to simulate this equipment, the 2-D Finite Element Method (FEM) has been used. In this paper, a novel FEM simulation analysis of the saturated core Superconductor Fault Current Limiter (SFCL) is proposed using the A-V-H formulation. The current distribution in the superconducting coil is observed. The results are compared to the limited fault current measurements and simulations available in the literature.

The fishing deck machinery is the tools used to collect fish in fishing activities. Fishing deck machinery is intended to improve the effectiveness of fishing operations. The mission of the Ministry of Marine Affairs and Fishery Year 2015-2019 in the Regulation of the Minister of Marine and Fisheries No. 45/PERMEN-KP/2015 which is a priority is to provide assistance for fishing facilities for fishermen; it is necessary to develop and optimize fishing deck machinery. To assure the safety and dependability of these fishing deck machinery, calculations, simulation and functional tests are needed. This paper discusses the prediction of structural failure in the design of fishing deck machinery a hydraulic type with finite element method simulation approach. The results of the FEM simulation analysis are (i) the maximum value of von-Mises stress is greater than the ultimate tensile strength of the material; (ii) 1st principal stress value minimum is smaller than the ultimate tensile strength of material; (iii). the Poisson ratio value higher than the Poisson ratio value of the material. Base on the simulation result, the structural design of fishing deck machinery is safety.
