It is the simplest and most economical type of transformer cooling, but it is also the least efficient. Natural air cooling is generally restricted for transformers up to 1.5 MVA.<\/p>\n<p>Transformers with higher ratings require more cooling than can be provided by natural air cooling. These transformers are typically cooled by forced air cooling or by oil cooling.<\/p>\n<p>Forced air cooling uses fans to circulate air over the transformer. This type of cooling is more efficient than natural air cooling, but it is also more expensive.<\/p>\n<p>Oil cooling uses oil to circulate heat away from the transformer.
