DESIGN OF SINGLE PHASE 1KVA DRY TYPE TRANSFORMER FOR NONLINEAR LOAD OPERATION

Abstract

This report, is about the design of single phase 1kVA dry type transformer for nonlinear load operation. For the introduction, the dry type transformer means the cooling system of the transformer is using air as the cooling medium. The material used to design the transformer is copper as the conductor material and CRGOS (Cold Rolled Grain Oriented steel) as core material to achieve higher efficiency, lower running cost and compact design. The non-sinusoidal or harmonically distorted currents drawn by nonlinear loads lead to excessive winding losses and overheating of the transformers. Therefore, to minimize or reduce transformer operating losses by using passive filter. In chapter 2 is literature review, the research paper have been reviewed, the ideas and method purpose related to this project. All the data review has been summarized and recorded for references. In chapter 3 is methodology, this project is presented which include block diagram, flow chart, software simulation and work plan for the whole project. This chapter, explain in detail about the material selection for design the high efficiency of transformer. Discuss the advantages and disadvantages on the type of transformer. Analyze nonlinear load effects and causes. Using technique filter to reduce or eliminate the distortion output. Lastly, in chapter 4 is the expected outcomes for this project based on literature reviews and case study. For the future planning, is to continue to design the circuit to get the correct value total harmonic distortion THD. Simulate the circuit and record the data. Based on what result that simulation come out as will be conclusion for this final year project proposal.
