What is Transformer Fault Diagnosis via DGA Analysis about?
The document discusses diagnosis of faults in a family of transformers using dissolved gas analysis (DGA). DGA testing revealed several issues: 1) All transformers showed high levels of hydrogen and methane indicating partial discharge inception. 2) Transformer 2 also showed high acetylene indicating low energy sparking in the in-tank tap changer. 3) All transformers exceeded limits for ethylene, indicating thermal faults in the oil from overheating or arcing. 4) High carbon monoxide and carbon dioxide i
