Abstract: The present invention relates to a Compact Secondary Substation (CSS) containing at least one transformer (6, 108, 208) which is connected to a high voltage input (110, 210) and through a low voltage switch board (112, 212) to consumers. The object of the invention is to perform cooling of a CSS in a way that mostly isolates the inner volume of the CSS from atmospheric air. This object can be fulfilled if the transformer is cooled by a cooling system comprising a heat exchanger (8, 104, 214) in which a first medium and a secondary medium are circulated, where the first medium contains heat generated by the transformer and the secondary medium is circulated through pipes or tubes arranged in the soil around the CSS and is thus cooled by heat transmission towards the soil. Such a CSS can also have a much smaller volume than a typical air-cooled CSS.
