Dissolved Gas-in-oil Analysis (DGA) is used widely in the power laboratory and industrial field as a sensitive and reliable technique for the detection of potential incipient fault condition within oil-immersed power transformers. However, there is still no universally accepted interpretation method for DGA data. IEC 60599 and IEEE C57.104 standards provide some methods for the interpretation of DGA data, but DGA interpretation is not an easy task since DGA methods often cannot provide a… CONTINUE READING
