Document Summary
Transformers do not have moving parts, nor are they energy conversion devices, however their ability to modify the current-voltage characteristics of a given load or source, make them invaluable components in energy conversion systems. They are utilized for power applications and in low power signal processing systems. One application in power transmission is the use of transformers on a transmission line utility pole commonly seen as a cylinder with a few wires sticking out. These wires enter the transformer through bushings that provide isolation between the wires and the tank. Inside the tank there is an iron core commonly made of silicon-steel laminations that are 14 mils (0. 014 ) thick. The insulation often used is paper with the whole coil system immersed in insulating oil. The oil increases the dielectric strength of the paper and helps to transfer heat from the core/coil assembly. An drawing of one such distribution transformer is shown in figure 2. 2 in your textbook.
