3D Acoustic Emission Transformer Monitoring

Underground Transmission Vault Robot

Project Summary

EPRI’s 3D Acoustic Emissions Transformer Monitoring project intends to explore improved techniques and algorithms for diagnosis of power transformers using Acoustic Emission. Through the deployment of multiple Acoustic Emission sensors on the faces of the transformer, information on the location of internal defects can be extracted.

Project Status

Project Phase: Demonstration

The project has two systems presently out in the field gathering data from gassing transformers. An ongoing parallel effort is analysis of the data to improve noise reduction and detect location accuracy.
