Abstract :
Acoustic emission-based partial discharge source location has been applied successfully to power transformers in both factory and field environments, and this method is becoming an established test procedure with a high success rate. With the aid of local utilities and utility laboratories that use acoustic emission apparatus daily, we expect further advances in this technology and an improved basis for determining suitable application conditions.
