FIELD: measurement.
SUBSTANCE: invention relates to electrical measurements. Essence of invention consists in the fact that in series circuit of device for measurement of inductances of dissipation of separate windings of double-winding transformer additionally includes winding auxiliary two-winding transformer with variable transformation ratio, and free windings of analyzed and auxiliary transformers are connected in series in reverse, wherein transformation coefficient of auxiliary transformer is selected equal to transformer ratio of measured transformer.
EFFECT: technical result is high accuracy of measuring inductances of dissipation of separate windings of double-wound transformer.
