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.

In daily operations to deal with transformer short circuit accidents, are to find out the essence of the problem through inspection and test. Transformer in the sudden short circuit, high and low voltage side will be subject to a lot of short circuit current, in the short time of the circuit breaker too late to break off, short circuit current and current square proportional to the electrical force will act on the transformer winding, the electrical force can be divided into radial force and axial force.
