Explain two types of transformer. |
| Answer» <p>Ans :- Step-Up Transformer</p><p>As the name states that, the secondary voltage is stepped up with a ratio compared to primary voltage. This can be achieved by increasing the number of windings in the secondary than the primary windings as shown in the figure. In power plant, this transformer is used as connecting transformer of the generator to the grid.</p><p>Step-Down Transformer</p><p>It used to step down the voltage level from lower to higher level at secondary side as shown below so that it is called as astep-down transformer. The winding turns more on the primary side than the secondary side.</p> | |
