摘要： Processes for processing bio-sourced oil to produce bio-sourced oil dielectric fluids can be carried out using an apparatus mounted on a mobile transport platform system having a total footprint of no more than about 30 m2. The processes use a described array of pumps, heaters, filters, a degasser and vacuum system, and an additive metering/mixing valve system to achieve production under low energy and pressure conditions.

摘要： A method of manufacturing an electrical device includes providing a composition comprising a mixture of vegetable oil fatty acid esters as a dielectric fluid in an electrical apparatus. The mixture of castor oil fatty acid methyl esters can contain the methyl stearate in a mass content of 1 to 20% to total amount of the mixture, the methyl oleate in a mass content of 1 to 90% to total amount of the mixture, the methyl linoleate in a mass content of 1 to 80% to total amount of the mixture, the methyl palmitate in a mass content of 1 to 50% to total amount of the mixture, the methyl ricinoleate in a mass content of 0 to 4% to total amount of the mixture, and the 10-undecylenic acid in a mass content of 0 to 1%.

摘要： A power cable includes a conductor, an inner semi-conductive layer covering the conductor, an insulating layer covering the inner semi-conductive layer and impregnated with insulating oil, an outer semi-conductive layer covering the insulating layer, a metal sheath layer covering the outer semi-conductive layer, and a cable protection layer covering the metal sheath layer. A minimum thickness t1 of a certain cross section of the metal sheath layer is less than or equal to 90% of a maximum thickness t2 thereof.

摘要： A system and method are described for regulating water concentration in a dielectric fluid. The system can comprise electrodes capable of applying an electric field across the dielectric fluid, thereby causing charge carriers and water included in the charge carriers to move toward a respective electrode. The system further includes a trap positioned near the electrodes and comprising a water absorbing material capable of trapping water, thereby reducing the concentration of water in the dielectric fluid. It is also possible to measure properties of the dielectric fluid and use such measurements to control the water-trapping process.

摘要： An electrostatic machine employs a high dielectric fluid comprised of a dielectric liquid with suspended dielectric particles. Electrorheological effects are minimized through small particle sizes and steric coatings on those particles limiting the minimum particle-to-particle distance. Low particle volume densities provide greater torque density with managed reduced viscosity.
