Abstract

The invention refers to a power transformer/reactor having a high voltage winding (2, 3) wound around a core (1). The transformer/reactor is a so-called dry type of transformer, i.e. air-cooled. According to the invention the high voltage winding is divided into a first section (2) and a second section (3) in series to each other. The winding is electrically connected (4, 5) to the core (1) between both these sections.
