Research of High-Voltage Discharge in Oil on a Simulator with a Various Set of Defects

The article describes a device for simulating various insulation defects for use with acoustic monitoring systems for power transformers. The parameters of the recorded signals of the simulator are given, this makes it possible to recognize various insulation defects when diagnosing power transformers under operating conditions. Simulator experiments were performed with a different set of defects. Values of parameters of acoustic control signals for various insulation defects of power transformers are obtained. Experiments of automated means of acoustic control have been made. Technical means have been developed to simulate various insulation defects in power transformers. A structural diagram of a simulator with a different set of defects has been developed. The device allows to reproduce various defects in the power transformers insulation, as well as to recognize such defects according to the proposed parameters of the acoustic control signals.
