Detection of acoustic emission signals from partial discharge sources in oil-pressboard insulation system

Partial Discharges are major source of insulation failure in power transformers. Therefore, partial discharge (PD) measurement has been commonly carried out to detect and monitor PD activity in insulation in order to avoid from any catastrophic failure. In this research work, acoustic emission (AE)...

In this research work, acoustic emission (AE) detection system is used to detect PD in an experimental tank filled with transformer oil.
