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: 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.

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 fluid components (A,B) which are a priori ingredients of the insulation fluid (10). The method comprises the step of carrying out at least one optical measurement and/or at least one gas chromatographic measurement on the insulation fluid (10). Using this measurement or these measurements or at least one additional measurement on the insulation fluid(10), a first concentration (cA) of the first fluid component (A) and a second concentration (c
B ) of the second fluid component (B) are derived. Then, using the first concentration (c
A ) and the second concentration (c
B ), and, advantageously, a dielectric breakdown strength E
bd of the insulation fluid (10), an operating state (O) of the electrical apparatus (1) is derived.

Abstract: A method and device for providing an insulation fluid (10) and for filling this insulation fluid (10) into medium-voltage or high-voltage switchgear (1) is provided. The method comprises method elements of mixing at least two fluid components (A,B) for yielding a first amount (M1) of insulation fluid (10), monitoring a first mixing ratio (R1) of this first amount (M1), and monitoring a second mixing ratio (R2) of a second amount (M2) of the insulation fluid (10) that is already in the electrical apparatus (1). The first mixing ratio (R1) is controlled such that no condensation of a fluid component (A,B) takes place. Furthermore, the first mixing ratio (R1) and the first amount (M1) of the insulation fluid are controlled using the second mixing ratio (R2), the second amount (M2), a desired target mixing ratio (R), and a target amount (M) of the insulation fluid.

Abstract: A method and device for estimating a density value ρm indicative of a true density ρ or for estimating a viscosity value ηm indicative of a true viscosity η of a fluid is disclosed. For this, a first resonance frequency fR of a first mechanical oscillator in a reference volume and a second resonance frequency fF of a second mechanical oscillator in contact with the fluid are measured. The estimated value ρm or ηm is then derived using these resonance frequencies fR and fF. During this derivation, at least one fluid-temperature- or fluid-pressure-dependent parameter of the fluid is used. Additionally or alternatively, the first (i.e. reference) mechanical oscillator is arranged in contact with a reference fluid. Thus, fundamental errors in the derivation of the estimated value ρm or ηm are reduced and the estimated value becomes more reliable.
