Influence of the switchboard type on parameters of an output impulse of the generator according to Vvedensky's scheme is analyzed. The technique of the switchboard choice is offered when using generator for diagnostics of a mechanical condition of power transformers windings. Switchboards were investigated: the mercury relay, the mechanical slider switch, the push-button switch, gas sealed-contact and vacuum sealedcontact, discharger. The technique of switchboards comparison consisted in comparison among them the impulses registered on coordinated loading at the exit of the created cable generator. Comparison of the initial and restored signals was carried out at different quantity of harmonicas. The technique for comparison of amplitudes ranges in the form of the power spectral density is offered. Research was carried out in the environment of MathCAD by means of Fourier's discrete transformation. The results of the study are given in the table.
