A transformer is a static electrical appliance that converts ac energy of one voltage class into AC energy of another voltage class of the same frequency by means of electromagnetic induction between coils. The transformer works on the principle of electromagnetic induction and consists of two windings that are insulated from each other and have unequal turns.

By Air Natural method the generated heat in the transformer is cooled by the circulation of natural air. When the temperature of the transformer becomes higher as compared to the temperature of the surrounding air, thus by the process of natural convection, heated air is replaced by the cool air. This method is also known as a self-cooled method.

What is the impedance voltage of a dry type cast resin transformer? The impedance voltage of the transformer is to short-circuit the secondary winding of the transformer, so that the voltage of the primary winding increases slowly. When the short-circuit current of the secondary winding reaches the rated current, the ratio of the voltage (short-circuit voltage) applied by the primary winding to the rated voltage is the percentage.
