Assessment of transformer paper ageing and post mortem investigation

Paris Session 2018

Tutorial

When a transformer is permanently removed from service, the opportunity arises to perform a detailed and destructive examination thus direct observations and measurements can be made and material samples collected for later examination. Of special interest are paper insulation samples for investigation of ageing. Also of great interest is the ability to capture valuable information on design and construction as well. Furthermore, the analysis of material samples drives future research and development.
