The invention relates to method for monitoring dissolved gases in liquid-filled high-voltage installations comprising a sealed separating vessel communicating with a liquid tank, wherein an equilibrium state of the liquid with the gas state prevails in the separating vessel during normal operation and liquid is pumped off from the separating vessel with a pump as to keep the liquid level at a predetermined height, including the following steps; Short-time interruption of the pumping action as to leave the equilibrium state and to increase the pressure in the separating vessel, and withdrawal of a gas sample from the gas phase above the liquid level in the separating vessel for the analysis thereof. The invention moreover relates to a method for monitoring dissolved and undissolved gases, wherein the method for monitoring dissolved gases is performed and undissolved gas is fed back into the separating vessel, and to a device for performing the methods according to the invention.
