Tech/Engineering - Electronics / Elect Eng / general terminology for transformers
Portuguese term or phrase: arvorejamento
This refers to stripping down and dismantling the insulating cylinder of a transformer to inspect for damage. Not sure what this term refers to, some sort of peeling effect or separation of the insulating paper layers?


Então, durante o desfolhamento das camadas do cilindro nestas regiões e em outras partes isolantes, foram visualizadas marcas de carbonização e arvorejamento.
