Abstract: The present invention relates to an offshore converter station (1) comprising at least one sealable room (4) containing amongst others a high voltage SF6 insulated converter installation. This sealed, but enterable room is filled with a non-toxic dielectric insulation gas containing next to dry air for example fluoroketone or hydrofluoro monoether. This allows for a smaller footprint of the offshore converter station.

Abstract: A method and device for operating a fluid-insulated electrical apparatus (1) are disclosed. The insulation fluid (10) of the electrical apparatus (1) comprises at least two components (A, B). The method comprises the step of determining a physical state of the insulation fluid (10) by measuring at least three measurement variables (p, p, T) by means of sensors (30). The method further comprises the step of deriving trend variables indicative of changes over time for the measurement variables (e.g. ρ, p, T) and/or for characterizing variables (e.g. p/T, PA/PB, PA/T, PB/T). These characterizing variables (p/T, PA/PB, PA/T, PB/T) are derived from the measurement variables (ρ, p, T) by using a relating equation, such as an equation of state, and are also indicative of the physical state of the insulation fluid (10). By testing for specific patterns of the trend variables, an operating state (O, Fl, F2) of the electrical apparatus (1) is determined. The possible operating states (O, Fl, F2) correspond to specific and distinguishable non-fault and fault scenarios for the electrical apparatus (1). Thus, operating states can be distinguished and troubleshooting in case of a failure is simplified.

Abstract: The invention relates to a method for deriving at least one operating parameter P of a fluid-insulated electrical apparatus (1), in particular of gas-insulated switchgear (1). The operating parameter P is dependent on a dielectric breakdown strength E
bd of an insulation fluid (10) of the electrical apparatus (1). The insulation fluid (10) comprises at least three components X, Y, and Z that are assigned to at least a first and a second component group A and B such that at least one component group comprises at least two components. The component groups A and B differ in their weighted average values of the molecular masses of the components in the respective component groups. Then, at least one quantity which is indicative of the concentration c
A of the first component group A and of the concentration c
B of the second component group B is determined from the insulation fluid (10), e.g. by measuring one or more measurement variables (p, p, T, λ, η, c
s ) by means of one or more sensors (30). The operating parameter P is then derived using the at least one quantity.

Abstract: The application relates to a method for determining a property of a fluid component of a fluid present in a compartment of an electrical apparatus by means of a measurement device arranged outside the compartment and comprising a chamber for receiving a quantity of the fluid from the compartment. Amongst other steps of the method, an optical path in the chamber is illuminated by a light source and a first intensity of light is measured by a light detector. Then fluid is released from the compartment into the chamber and a second intensity (Ix) of light is measured. Based on these measurements the property of the fluid component is determined.

Abstract: A method for determining an average temperature of a fluid in a closable container (1) comprising: providing a duct (4) with first opening (11a) and second opening (11b), positioning a flow preventing element (7) in the duct (4), positioning a density sensor (3) or first pressure sensor (3) inside the duct (4) or container (1), attaching the duct (4) to a container outside wall, stabilizing a temperature of the duct wall (10) to a constant reference value, determining a difference between a first pressure of the fluid on one side and a second pressure of the fluid on the other side of the flow preventing element (7), measuring a local density of the fluid by the density sensor (3) and/or a local pressure by the first pressure sensor (3), and deriving the average temperature from the local differential pressure, the local density and the reference duct temperature.

Abstract: The present invention relates to an apparatus for the generation, the distribution or the usage of electrical energy, said apparatus comprising a housing enclosing an insulating space and an electrical component arranged in the insulating space. The insulating space contains a dielectric insulation gas comprising an organofluorine compound A. The apparatus further comprises a molecular sieve arranged such as to come into contact with the insulation gas. The molecular sieve has an average pore size y greater than the molecular size of at least one decomposition product of the organofluorine compound A generated during operation of the apparatus. The adsorption capability of the molecular sieve for organofluorine compound A is lower than for the at least one decomposition product. According to the invention, the apparatus further comprises at least one desiccant arranged such as to come into contact with the insulation gas.
