摘要： A method of performing a circuit-breaking and closing operation in a three-phase system having a first phase, a second phase lagging the first phase by 120°, and a third phase lagging the first phase by 240°, includes: a) opening only one of the first phase, the second phase and the third phase before a zero crossing of a current of the corresponding phase, b) opening the remaining phases of the first phase, the second phase and the third phase after step a), and c) closing the first phase, the second phase and the third phase simultaneously or essentially simultaneously at a phase to ground voltage of the phase of the first phase, the second phase and the third phase which lagging the phase that was opened in step a) by 120° in a time range from 60° before a peak of the phase to 90° after the peak.

摘要： Systems and techniques for beamforming are disclosed. Codebook antenna ports, such as ports defined by the 8 transmit antenna LTE codebook, are mapped to sub-elements of an antenna array arranged to form a plurality of elevation and azimuth ports, such as 4 elevation and 2 azimuth ports or 2 elevation and 4 azimuth ports. The mapping is chosen so as to optimize performance. Phasing values may also be applied to signal components provided as inputs to the sub-elements, with the values chosen to maximize performance, such as rank 1 gain or rank 2 or higher performance.

摘要： A system which permits the measurement, during operation, of the arc voltage electrodes having an upper metal portion (4) cooled by circulating water. The system employs an electrical instrumentation-cable (16) attached to a piece (5) for fixing the graphite consumable portion (3) of the electrode. This cable runs along the axis of the metal portion (4) and then inside one of the water-supply pipes (11), terminating at an electronic box (14) which converts the incoming measurement signal into a light wave.

摘要： Iron metal is continuously smelted in an electric arc furnace having three electrodes energized with three-phase current. Solid material rich in iron metal is continuously fed into a zone of the furnace hearth proximate two electrodes generating long and strongly radiating arcs and molten metal is continuously discharged in a zone of the hearth proximate the third electrode generating a short arc of limited radiation. This method is useful for continuously processing scrap-iron or pre-reduced solid material in the continuous production of steel.
