A tow-year project initiated by EPRI in 2006 has focus attention on Extending the useful life of power transformer so as to increasing the life of the power transmission and distribution infrastructure.
Central of the project features with effective transformer diagnostics and condition assessment.
The project aims to process data from testing in-tank, fiber optic partial discharge sensors and developing better transformer tank penetration methods for sensor insertion.
The project includes:
1. Develop a method and then manufacture and test prototypes of a cost-effective penetrator mechanism and sensor system suitable for retrofit into transformers
2. Obtain proof-of-concept of internal fiber optic pd sensors in an operating transformer with known pd
3. Establish an initial database to characterize the pd signals to the type of fault.
