Abstract (en)
The present disclosure provides a method of operating a transformer (200), wherein the transformer (200) generates heat when being operated, and wherein the transformer (200) includes a cooling unit (110) for forced cooling of the transformer (200). The method includes generating by the cooling unit a flow (150) of a coolant along a cooling path (170) for forced cooling of the transformer (200), measuring a true power value supplied to the cooling unit (110), and comparing the detected true power value with a predetermined true power threshold value.
