| Summary: | This theses describes result of simulation flux distribution and loss calculation on
three phase transformer core 100kVA using FEM. From these theses, best material and best T-Joint configuration can be found. It’s important to make sure transformers work at 100% efficiency. Transformer is a device that transfers electrical energy from one circuit to another circuit with a shared magnetic field. Transformer can converts voltage by step-up and step-down. The transformer core is used to provide a controlled path for the magnetic flux which generated in the transformer. The core is built up from thin sheet – steel with
many layers of lamination. The lamination that is used to reduce heating on transformer
core will cause power losses. Three types of transformer core were used in this simulation
such as M5, MOH and ZDKH. T-Joint configuration is importance in avoidance the losses. Transformer core configurations in this simulation were 23˚ T-Joint, 45˚ T-Joint, 60˚ TJoint and 90˚ T-Joint. Simulation on power loss and flux distribution will be done by using FEM software called Quickfield 5.5. QuickField is an interactive environment for electromagnetic, thermal and stress analysis. QuickField can perform linear and nonlinear magnetostatic analysis for 2-D and axisymmetric models. Flux density for M5 was 1.79T better than the MOH and ZDKH material which only 0.207T and 0.214T. Best T-Joint
configuration for each material was 60˚ T-Joint. Flux line, flux density and T-Joint
configuration were an important factor in causing the differences in performance. |
