MULTIDECADE INDUCTIVE VOLTAGE DIVIDER Russian patent published in 2004 - IPC

FIELD: electric measuring equipment, applicable as a wideband multidecade voltage divider with improved metrologic characteristics. SUBSTANCE: the device has previous and subsequent decades, each of them is made of the first and second additional five-section windings with taps, and the main ten-section winding, whose beginning, end and the center-tap are connected respectively to the beginning of the first, end of the second and the common point of connection of the additional five-section windings, multi-position switches, the taps of the extreme sections of the main ten-section winding, the first and second additional five-section windings of the previous and subsequent decades positioned on a common ferromagnetic core are interconnected, in the previous decade the end of the third and the beginning of the fourth additional six-section windings are connected to the tap-tap of the main ten-section winding, and the rest taps, with the exception of the extreme taps, are connected to the respective taps of the first and second additional five-section windings. EFFECT: enhanced precision of the division ratio within a wide band of frequencies and reliability of the multidecade inductive voltage divider. 5 dwg, 1 tbl
