Express diagnostics of power oil transformers by vibroacoustics and partial discharges

Abstract

This article presents the results of Express Diagnostics conducted in the working state of the autotransformer ATDTN-125000/220/110-U1. Three measurement pribors were used in the research process to determine the vibroacutic, partial discharge, and current strength values in the working state of the oil power transformer. Experimental studies and their analysis have shown that by evaluating the technical condition of the oil power transformer at a short opportunity, it is possible to give a conclusion to its ecpluation or release into repair.
