METHOD FOR DIAGNOSTICS OF INDUCTIVE WINDINGS Russian patent published in 2011 - IPC G01R31/06 

FIELD: electricity.

SUBSTANCE: diagnostics of inductive windings is carried out with the help of an auxiliary electric circuit comprising a capacitor with a variable capacitance value and a resistor with a variable resistance value at nominal current values, at which implicit faults of inductive windings may show. Auxiliary elements are connected - a capacitor with a variable value of capacitance to one output, and a resistor with a variable resistance value to the other output of an inductive winding. The produced electric circuit is connected to linear outputs of the secondary winding of the transformer connected as delta, with amperemetres connected to its first and second outputs. Equality of amperemetres readings is a criterion of good condition for all connected identical inductive windings.

EFFECT: expanded opportunity of inductive windings diagnostics.
