Abstract: An arrangement for an overvoltage protection of a subsea electrical apparatus and a method for operating it. The arrangement includes a tank submersible below a water surface level, an electrical apparatus accommodated in the tank, and a surge arrester arrangement accommodated in the tank and coupled to a power supply of the electrical apparatus in the tank for providing the overvoltage protection of the electrical apparatus. The arrangement further includes a controllable grounding switch for connecting the surge arrester arrangement to a ground point in response to a control of the grounding switch to a closed state and for disconnecting the surge arrester arrangement from the ground point in response to a control of the grounding switch to an open state.

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.
