Abstract


Microstructure of the fractured transformer conductor features the mechanism of the failure. The difference of the microstructures in different part of the fractured conductor can be identified by macro observation, SEM and EDS analyses. The macro and micro morphologies, chemical composition are described as parameters for the qualitative analysis of the fracture of the conductor.
