For small rating transformers (5 to 10 kVA), the external surface is sufficient to dissipate heat. This type of transformer uses enclosures for air convection and heat released by natural radiation from the case itself. Generally, instrument transformers (except higher voltages) are dry type and use this method for cooling.

WebAN cooling Method. In a dry-type transformer, the air is only the medium to take away the heat generated in the transformer. The fans are used to force the cooling of the winding and core of the transformer. This type of cooling is called AN (Air Natural). This is all about the cooling methods of the transformer.
