INDUCTIVE WINDING DIAGNOSTIC PROCEDURE Russian patent published in 2014 - IPC G01R31/06 

FIELD: electricity.

SUBSTANCE: auxiliary three-phase electric circuit contains in the first phase a capacitor of variable capacity and the first ammeter connected in-series to it; in the second phase it contains resistor with variable resistance value and in the third phase inductive diagnostic winding with the second ammeter connected to it in-series. The resultant electric circuit is connected to linear inputs of the secondary winding of transformer connected as per triangle scheme with variable voltage. Equality of ammeters readings is a criterion of good condition for all connected identical inductive windings.

EFFECT: enhanced inductive winding diagnostics.
