The transformer is a static device and has rotational losses. When transformers transfer power, they do so with a minimum of loss. Transformers are widely used in many sectors such as industrial sector and commercial building. Modern transformer designs typically exceed 95% efficiency and it is good to know where some of this lost power goes. Transformer is a device for converting electric energy at one voltage level to electric energy at another voltage through the action of magnetic field. The power loss of transformer cores can still be considerably reduced by improved joint design based on new knowledge of the localized flux distribution, both in the corners and in the limbs. Rotational flux will be measured in the T-joints 45º of experimental cores, and it has been found to cause localized high loss regions dependent on the joint design. The star connection is used in industrial application for electrical energy distribution. Circulating harmonic fluxes have been found in individual laminations in the limbs of three-phase cores. The path of the harmonics is independent of joint design although their magnitudes are dependent. The conclusion for this project is to determine the effect of voltage and current relationship in the three phase transformer connection. 2009-01-29T02:49:22Z 2009-01-29T02:49:22Z 2008-03 Learning Object http://hdl.handle.net/123456789/4282 en Universiti Malaysia Perlis School of Electrical Systems Engineering |
