DESIGN AND CONSTRUCTION OF 2000V A, 230V TO 530V STEP UP TRANSFORMER

Abstract

The project was carried out to design and construct a step up transformer capable of stepping a 230 volts input supply to 530 volts output at 2000 watt. This was effectively achieved by first designing the transformer; taking into consideration the underlying principle of operation of the device, the power rating of the device, the cross sectional area and number of lamination sheets that can provide the flux for the transformer rating. The minimum cross sectional area of the primary windings that can withstand a power of 2000 watts was also determined. This was followed by calculation of the number of windings to give 230 volts input primary voltage and then the transformer ratio formula was used to calculate the number of secondary winding. The design simplified the construction process. It was ensured that the coiling of the windings was uniform to ensure a uniformly distributed magnetic field during mutual induction so as to increase transformer efficiency. Analog meters were incorporated with the transformer during construction to display both primary and secondary voltage ,values.
