Abstract
A subsea arrangement including at least one canister including a chamber accommodating at least one circuit breaker. The chamber is filled with a gaseous dielectric medium constituting a quenching medium for the at least one circuit breaker in the chamber. The pressure in the chamber is balanced against ambient sea water pressure by a pressure balancer, which includes at least one pressure container containing a pressurized gaseous medium of a same type as the gaseous medium in the chamber. The pressure container is connected to the chamber via a control valve, which is arranged to be controlled by the ambient pressure so as to feed pressurized gaseous medium from the pressure container into the chamber when the ambient pressure increases in order to maintain the pressure in the chamber equal to the ambient pressure.
