Investigation of high-voltage discharge in oil on a simulator with a different set of defects

Abstract

Background: The article describes a device for simulating various insulation defects for use with acoustic control devices for power transformers included in the power supply system of railway transport. The parameters of the recorded signals of the simulator are given, which will make it possible to recognize various insulation defects when diagnosing power transformers under operating conditions which will help to avoid emergency modes and interruptions in the operation of the electric rolling stock of railways. Aim: experimental studies of a simulator with a different set of defects, obtaining the values of the parameters of acoustic control signals for various defects in the insulation of power transformers. Methods: experimental studies of automated means of acoustic control, development of technical means for simulating various defects in the insulation of power transformers, processing of acoustic control signals. Results: the block diagram of the simulator with a different set of defects is given, the values of the parameters of acoustic monitoring signals for various defects in the insulation of power transformers are given. Conclusion: the above device allows you to reproduce various defects in the insulation of power transformers, to recognize such defects according to the proposed parameters of acoustic control signals.
