Abstract
The disclosure relates to a transformer arrangement comprising a transformer which comprises at least one phase winding. The phase winding has coil turns around a coil axis. The transformer arrangement further comprises a transformer tank having walls forming an enclosure in which the transformer is arranged. The enclosure contains an incompressible medium in which the transformer is immersed. A screen is arranged in the transformer tank, between the walls of the transformer tank and the at least one phase winding of the transformer. The screen has an inner, transformer-facing, surface and an outer, wall-facing, surface. The transformer tank has a first wall extending transversely to a first axis adjacent to a first end of the transformer and an opposite second wall extending transversely to the first axis, adjacent to a second end of the transformer.
