| dc.description.abstract | This project has presented the design of 1 kVA rated power, 200/100 V
and cable of 1.5 cross sectional area. The design of transformer coil starts
with the selection of number of turns of coil and selection of cable cross
sectional area. Once the turns of coil and conductor sections are known, proceed
further toward estimating the coil configuration up to the window height of the
core frame. Based on the calculated window height, the secondary coil design
was done. Furthermore, the core width, core stack, flux density and window
width are calculated with the design output available. Besides, the material
preparation and working details transformer assembly are also done. After the
transformer is complete assembled, some of the tests such as polarity test, ratio
test, open-circuit test, short-circuit test and load test are carried out. Finally, the
tested results are analyzed, the losses and efficiency of transformer are counted.
Some of the discussions and recommendations are stated for future project
improvement. Since the efficiency of the transformer design is 92.50 %, thus it is
effectively designed for reducing the line cost and improving the reliability and
quality of the electrical energy supply system. | en_US |
