    摘要： A support bracket for supporting insulating rods inside an insulator tube of a hollow core insulator. The support bracket includes a cylindrical ring with an outer surface for abutting against the inner surface of an insulator tube, an inner surface for supporting an insulating rod and two opposing end sides, denominated by first and second end sides. The support bracket includes an expansion assembly configured to be actuated so as to expand the cylindrical ring in at least one radial direction when the support bracket has been inserted in an insulator tube of a live tank circuit breaker.

    摘要： Predistortion that will compensate for distortion introduced by a power amplifier circuit is determined by applying a time-varying reference signal to the power amplifier circuit, wherein at each moment the time-varying reference signal has a reference amplitude and a reference phase. A corresponding output signal supplied by the power amplifier circuit is measured, wherein at each moment the output signal has a measured amplitude and a measured phase. Amplitude predistortion is determined by comparing the reference amplitude with the measured amplitude, and phase predistortion is determined by comparing the reference phase with the measured phase. A relationship between the phase predistortion and the reference amplitude is determined such that, for any value of the reference amplitude, a corresponding value of the phase predistortion is identified.

    摘要： A method for scheduling of periodic real time processes in an operating system, comprising the steps of defining a reference point in time for a periodic real time process, and scheduling the periodic real time process from said reference point in time. Preferably a future point in time is defined as said reference point in time at the start up of the operating system. Said real time process is preferably a periodic control process during which a relative control point in time, counted from the beginning of the subsequent control cycle, is calculated during each cycle with absolute time correction counted from said reference point in time. Said absolute time correction corresponds to the period of the periodic process multiplied with the number of passed control periods until said beginning of the subsequent control cycle, at which said absolute control point in time is calculated through an addition of said relative control point in time with said absolute time correction. In one embodiment the method according to the invention is applied in an active filter for compensation of variations in an apparatus current consumption from a power grid as a result of changes in the apparatus' electrical load.
