摘要： A method of eliminating a disturbing component from a periodic signal. The method includes the steps performing at least two measurements on the signal at two distinct instants, calculating the parameters of the disturbing component on the basis of the measurements, and subtracting the disturbing component from the signal. The invention is applicable to making an electronic capacitor voltage transformer comprising a capacitor divider constituted by a high tension capacitor and a low tension capacitor. The transformer includes a microprocessor programmed to perform the above method on the signal from the low tension capacitor.

摘要： A Rogowski coil is used as a precise current and temperature measuring device (in particular a device that is highly insensitive to temperature variations). The Rogowski coil is of the type including at least one printed circuit plate provided with a circular cutout. The coil is implemented by metal deposits on each of the two faces of the plate and extending along radii such that geometrical projections thereof pass through the center of the cutout. Electrical connections between the radii on one face and those on the opposite face are implemented by plated-through holes that pass through the thickness of the plate.
