Dissolved Gas Analysis of 115 kV Steel Industry Transformer using new IEEE Standard

This paper discusses the application of the IEEE C57.104-2019 standard to analyze faults in transformer of steel industry. The IEEE C57.104-2019 standard provides clearer details than the IEEE C57.104-2008 standard. It uses statistical data obtained from oil samples from various DGA experts who have collected transformer oil sample data for decades. This standard also provides analytical examples to allow the user clearly understand the process in this standard.
