| Riassunto: | Title screen In this article we described a scheme of a substitution of transformer winding with a defect in the form of closed loop coil. In terms of supposition of the presence of the magnetic couple between the undamaged winding and closed loop coil we can build the model of the diagnosis of the transformer winding. In the probing of the transformer winding with the defect in the form of closed loop coil with scanning pulse presence the voltage jumps appear in the undamaged part of the winding. From the tangent of the voltage logarithm of the undamaged winding we can derive the information about the closed loop coil parameters. We made an example of a calculation of the diagram dependences, which demonstrate a proper kink of a current derivative of the undamaged part of the winding in case of the closed loop coil defect. We described diagrams of the dependences of the kink of a current derivative on the scattering coefficient. We have shown that the kink of the derivative is becoming stronger in case of matching of the parameters of the kink of the undamaged part and closed loop coil one.
