Abstract

Transformer is a static electrical device that transfers energy from one electrical circuit to another by magnetic coupling. It is often used to convert between high and low voltages and accordingly between low and high currents. A simple single phase transformer consists of two electrical conductors called the primary coil and the secondary coil. There was two type of transformer; step-up transformer which the secondary coil has more turn then the primary coil and step-down transformer which secondary coil has fewer turns than the primary coil.
In this thesis, the transformer is a step-down type. This transformer will step down voltage from 240V to 24V and rating of 75VA. The size and length of the wire have being measure. The number a is need to be calculated, a is ratio of the input voltage per output voltage. To find the turn of coil, the ratio can be used by a is equal to primary turn per secondary turn. If a is higher than 1, it is step-down. If a is small than 1, it is step up.
The proposed of project is to make the transformer related the correct voltage. The ratio is 10. By calculating, the number of the primary coil is 1159 turn and secondary coil is 116 turn. The rating also needs to be correct. By calculation also, the size and the length of wire can be measure.
