CHAPTER ONE
A transformer is a magnetically coupled coil used in transmission of an electric power.
This coil may be electrically link, but not electrically linked as in two winding transformer.
It consists of primary winding and secondary winding which the number of turns varies depending on the type of transformer. Transformers are operated by the principle of mutual inductance between two separate coils wound on the same core.
There is also the step – up and step – down transformer. This work looks into the construction of a step – up auto transformer.
auto – transformer is the transformer that consists of only one is winding port of the being common to both primary winding and secondary winding.
That theory of an auto transformer and it operation is similar to that of the two winding transformer, it has high efficiency where cheap (because it used less copper) it is applicable where transformer ratio is little differs from unity.
- STANDARD WIRE GUAGE: These are specific number of a wine (coil) it is used in this project to gauge on 17 which has a diameter of 1.422m.
- TRANSFORMER: It is a cutout shape rubber material with a hollow in the center and with grove around is to avoid electrical link between the core and the coil.
- VOLTMETER: This is the instrument used to measure the voltage across the circuit. It is connected in parallel to the winding
- INSULATOR: These are the material used to isolate two conductors from touching each other.
