Title:
METHOD AND DEVICE FOR THE MONITORING OF GASES
Document Type and Number:
WIPO Patent Application WO2001086284
Kind Code:
A3
Abstract:
The invention relates to a method for the monitoring of dissolved gases in fluid-filled, high-voltage units, comprising a closed separating chamber, connected to a fluid tank, whereby an equilibrium between the liquid and gaseous state exists in a separating chamber, during normal operation and fluid is pumped out of the separating chamber, by means of a pump, in order to maintain the fluid level at a particular level. Said method comprises the following steps: a short interruption of the pumping process, in order to disturb the equilibrium and raise the pressure in the separating chamber and removal of a gas sample from the gas space above the fluid level in the separating chamber for analysis. The invention further relates to a method for the monitoring of dissolved and undissolved gases, whereby the method for monitoring dissolved gases is carried out and undissolved gases are introduced into the separating chamber and a device for carrying out the method according to the invention.
