FIELD: electricity.
SUBSTANCE: invention relates to subsea electrical systems. Pressure compensated subsea electrical system comprises housing (8) filled with dielectric liquid (12). Housing has first housing portion (8a) and second housing portion (8b) in pressure communication with each other. First housing portion comprises transformer (3), and the second housing portion comprises power converter (4). Pressure compensated subsea electrical system comprises pressure compensator (2) arranged to compensate pressure inside the housing. Pressure compensator is enabled to compensate pressure in both the first housing portion and the second housing portion.
EFFECT: higher reliability.
