Application and analysis of dielectric loss measurement of 110 kV transformer
In this paper,during the installation and commissioning of two 110kV main transformers of the natural gas cogeneration project,the dielectric loss of the transformer needs to be measured before the AC withstand voltage,the abnormal test data needs to be analyzed,the measurement re-sults are comprehensively judged,and after many discussions and studies,the conditions of the main transformer withstand voltage are finally met.Accurate analysis and judgment of test data can find the overall or local defects of the transformer in advance,reduce the hidden dangers of large-capacity transformers in the withstand voltage test or operation,and is of great significance for the measurement of dielectric loss of oil-immersed transformers.
