The method of measuring the resistance and the leakage inductance of the windings autotransformer with a rated voltage ratio equal to 1:1

摘要

method of resistance measurement and inductance of winding autotransformatora rated transmission napiu0119ciowej 1: 1, with a specified frequency supply voltage, which is a small voltage differentials arising from error measurement circuit is, the resistance value of r1, r2 and the inductance of le1,le2 winding is replaced with the measurement results autotransformatora laden flow il0, carried out in three different stages of measurement, in which in one stage is measured fazoczule voltage differential. the common winding u1 between autotransformatora standard (as) and autotransformatora considered (ax) of the same automatic transmissions)in the second stage, the resistor r in series of low value resistance to one of the voice coils autotransformatora (ax) and is measured fazoczule difference voltage. u2, as in stage 1, and in the third stage moving resistor r to the second coils autotransformatora (ax) and is measured fazoczule difference voltage. u3, as in stage 1, and then for the winding autotransformatora (ax)where in stages 2 and 3, incorporated was the resistance r is calculated impedancje dispersion zx1, zx1 model: (i) and (ii).
