Summary
This Technical Brochure provides new rules for the interpretation of DGA in electrical equipment, taking into account the type and location of faults. It identifies the faults that are of lesser concern in transformers (e.g., stray gassing of oil or hot spots T3-H in oil), and those which are potentially more dangerous (e.g, carbonization of paper C and arcing in paper). It also provides gas level limits which are more specific of these types of faults.
