Abstract
This dissertation studied the mechanisms of transformer health in terms of energy and dissolved parameters and establishes a novel method to identify a trigger for a change in transformer condition from normal to defective state. The study took the form of both analytic research to create a low energy degradation model and then empirical testing of the model on field data in the form of dissolved gas analysis as recorded from 201 GSU transformers that have either failed or are presently in service.
