TRANSFORMERS
A transformer changes electrical energy of a given voltage into electrical energy at a different voltage level. It consists of two coils that are not electrically connected, but are arranged so that the magnetic field surrounding one coil cuts through the other coil. When an alternating voltage is applied to (across) one coil, the varying magnetic field set up around that coil creates an alternating voltage in the other coil by mutual induction. A transformer can also be used with pulsating DC, but a pure DC voltage cannot be used, since only a varying voltage creates the varying magnetic field that is the basis of the mutual induction process easa part 66 module 3 ebook.
A transformer consists of three basic parts. (Figure 15-1) These are an iron core which provides a circuit of low reluctance for magnetic lines of force, a primary winding which receives the electrical energy from the source of applied voltage, and a secondary winding which receives electrical energy by induction from the primary coil easa part 66 module 3 ebook.
The primary and secondary of this dosed core transformer are wound on a dosed core to obtain maximum inductive effect between the two coils. There are two classes easa part 66 module 3 ebook
