A Novel Extension Method for Transformer Fault Diagnosis [PDF]

open access: yesIEEE Power Engineering Review, 2002
Dissolved gas analysis (DGA) is one of the most useful techniques to detect incipient faults in power transformers. However, the identification of the faulted location by the traditional method is not always an easy task due to the variability of gas data and operational variables.
