| Summary: | This project will show the flux distribution simulation and loss calculation on three phase transformer core 1000kVA using Finite Element Method. Transformer is static device that convert electrical energy from one electric circuit to another, with fix frequency, by the principles of electromagnetic induction either increases (steps up) or decreases (steps down) AC voltage. A transformer does not generate electrical power. It transfers electrical
power from one AC circuit to another through magnetic coupling. The transformer core is
used to provide a controlled path for the magnetic flux which generated in the transformer. The core is build up from thin sheet-steel with many layer of lamination. The lamination is use to reduce heating on transformer core which will cause power loss. For this project, a grain oriented silicon steel M-5 chosen as steel sheet for the transformer. The T-Joint configuration that used in this simulation is 23°, 45°, 60° and 90° will test with four packet
of transformer which is in different size of. The simulation will use Finite Element method software called Quickfield 5.5. QuickField 5.5 is a very efficient Finite Element Analysis package for electromagnetic, thermal and stress design simulation with coupled multi-field analysis. From the result of the simulation, it show that the direction of flux line for the transformer lamination is based on the direction of the limb. The result also shown that the 60° T-joint is the best configuration of the transformer lamination and transformer lamination with different packet is more efficient than with the same packet. The best configuration and the most efficient of transformer lamination recorded the lowest losses. |
