Abstract: A device comprising a group of electrode elements for a condenser separator of a two-step electrofilter, which group of electrode elements comprises at least two electrode elements in the form of strips or flat planar sheets, the electrode elements being mostly comprised of a core. At least one of the electrode elements or group of electrode elements is formed of at least two different polymers with different electrical properties. A first portion of the electrode element that is disposed closest to an adjacent second electrode element in the condenser separator is formed of an insulating polymer, and a second portion of the electrode element is comprised of at least one current conductive element in the form of a thin coating on the core of the electrode element, or is embedded in the core.

Abstract: A device comprising a group of electrode elements for two-step electrofilters in a condenser separator, which group of electrode elements comprises at least two strip shaped electrode elements (A, B), or two groups of planar disc-shaped electrode elements (A, B), the electrode elements (A, B) to a major part being comprised of a core (M1), and wherein at least one of the electrode elements (A, B) or group of electrode elements (A, B) is formed of at least two different polymers with different electrical properties, wherein a portion (M1, M3, M3?) of the electrode element (A) that is disposed closest to an adjacent second electrode element (B) in the condenser separator is formed of a polymer having a surface resistivity of more than 1×1012 ohm/kV, and wherein a second portion of the electrode elements (A, B) is comprised of at least one current conductive element (M2, M2?, M2?) in the form of a polymer in the form of a thin coating on the core (M1) of the electrode elements (A), or is embedded in said core (M

Abstract: A filter apparatus includes at least one filter, each filter being tunable and including at least one capacitor arrangement. The capacitor arrangement includes a plurality of first capacitors, a plurality of second capacitors, and a plurality of switches. Each switch is switchable between a non-conducting mode and a conducting mode. The plurality of second capacitors and the plurality of switches are arranged to connect or disconnect the second capacitors on different potentials in order to tune the filter by adjusting the capacitance of the filter. An electrical power transmission or distribution system includes such a filter apparatus. A method is provided for filtering harmonics in an electrical power transmission or distribution system by means of such a filter apparatus.

Abstract: The invention relates to a liquid cleaning device that is intended for purifying liquid from pollutants, which liquid cleaning device includes a vessel, having a lower chamber and an upper chamber, which lower chamber is connected to a heating member arranged to heat the liquid in said lower chamber, as well as further including a riser and liquid-distributor member, which riser is arranged to transport heated liquid from said lower chamber up to the upper part of said upper chamber, where the liquid-distributor member is arranged to impart the heated liquid an increased area of exposure to surrounding air, the liquid then, by means of the gravity, running back downward outside the riser and being collected in the lower part of the upper chamber of the vessel, said upper chamber and lower chamber being in at least conditioned communication with each other in order to allow transfer of the liquid from the upper chamber to the lower chamber.

Abstract: The present invention refers to a device (1) for cleaning fluid from contaminating matter, which device comprises a vessel (11) for fluid, a heating element (12) for heating fluid, control electronics (13) to control the heating element (12), and also a temperature sensor (14) for measuring the temperature of the fluid. The control electronics (13) is adapted to lower the heating capacity of the heating element (12) when the fluid has reached a predetermined temperature according to temperature sensor (14) and thereafter let the fluid be heated by a lower effect during a predetermined time period according to a time measuring unit (15) belonging to the device. This time measuring unit (15) comprises a frequency counting unit (15a), adapted to count periods in the supply current (16) input to the device (1).
