Application of Converter Transformer Defect Detection Based on Transformer Integrated Monitoring System

Abstract

This paper introduces an abnormal oil color spectrum of converter transformer during commissioning of UHVDC transmission project. The application of transformer integrated monitoring system based on ultrasonic local discharge, UHF local discharge and high frequency local discharge integrated software and hardware is used to detect and locate the floating potential discharge defects of converter transformer. The rheologic voltage is carried out by endoscope to locate and other parts The method of in-chip inspection verifies the feasibility of the integrated monitoring system for finding similar discharge defects of converter transformer, and provides an effective detection method for fast and accurate detection of transformer defects.
