Failure Analysis of Transformers

Transformer Microsections

 

Failure analysis of transformers involves a combination of x-ray imaging, dissection, microsectioning, optical microscopy, and SEM/EDS analysis in order to isolate and characterize the root cause of the failure, since transformers are very often potted in an encapsulant. 

Failures in transformers and a transformer microsection are shown below.
