Abstract :
In this work the electrical method of partial discharge (PD) impulse registration in the insulation of autotransformers is considered. The scheme of PD impulses registration by means of the radio digital oscilloscope is offered, as a technique of noise immunity. The features of PD impulses by character of the oscillograms are considered on the basis of which the algorithms of PD impulses visual identification are developed. To identify the defect images, the neural networks (NN) approach is considered.
