A reactive power compensation system includes a reactive power compensation device and a transformer electrically connected to the reactive power compensation device and having a cooling unit. The reactive power compensation device has an enclosure housing power electronics and at least one fan which provides an airflow for cooling the power electronics. The enclosure further includes an air outlet through which the airflow exits the enclosure after cooling the power electronics. The air outlet and the airflow are directed toward the cooling unit of the transformer to provide supplementary cooling to the transformer. The transformer cooling unit comprises external cooling fins in a liquid-filled transformer embodiment and comprises an air inlet of the transformer housing in a dry-type transformer embodiment. An optional duct may be provided between the enclosure and the transformer cooling unit.
