Abstract :
Although a detailed explanation of all the data presented here has not yet been formulated, it seems likely that aging of transformers can be qualitatively assessed using DRA (dielectric response analysis) and PD measurements at operating temperatures. It may also be possible to apply such measurements to generators, motors, and circuit breakers.
