Abstract :
Dissolved gas analysis (DGA) has long been recognized as the best method for the detection and identification of incipient faults in power transformers. This work presents an online condition assessment and diagnosis system for traction transformers, based on dissolved hydrogen analysis (DHA), that can provide fault diagnosis and real-time fault alarming for traction transformers.
