Transformer oil provides electrical insulation by increasing dielectric strength between live parts and grounding surfaces. It suppresses partial discharge, fills insulation voids, and prevents arcing. Oil also protects solid insulation from oxygen and moisture, maintaining long term dielectric reliability.
