Abstract: The present invention relates to a static electric induction apparatus (1b) comprising a winding (2) including a plurality of winding units (3), at least one first spacer element (5) arranged between the winding units (3) and including a first groove (18) defined in the surface thereof, and a sensor system for monitoring the temperature in the apparatus, wherein the sensor system comprises an elongated and flexible temperature sensing element (16) disposed in the first groove. The first groove (18) has a curved part that receives the flexible temperature sensing element which is wound at least one revolution in the first groove (18). The first groove enters and exits the first spacer element in one and the same end of the first spacer element. The apparatus comprises an elongated second spacer element (14a) extending in an axial direction on the outside of the winding (2). The second spacer element (14a) comprises an elongated second groove (22) arranged in communication with the first groove, and the flexible temperature sensing element (16) is disposed in the first and second grooves.

Abstract: A pressure compensated subsea electrical system and a pressure compensated subsea electrical system which has a housing filled with a dielectric liquid. The housing has a first housing portion and a second housing portion in pressure communication with each other. The first housing portion includes a transformer, and the second housing portion includes a power converter. The pressure compensated subsea electrical system includes a pressure compensator arranged to compensate pressure inside the housing. The pressure compensator is enabled to compensate pressure in both the first housing portion and the second housing portion.
