1. How does moisture enter a transformer?
Moisture infiltrates through breather ingress, insulation degradation, and leaks during maintenance, reducing oil performance and insulation quality.
2. What impact does moisture have on transformer performance?
It lowers breakdown voltage, accelerates insulation aging, and increases failure risks, significantly reducing transformer lifespan.
3. How can moisture be removed from transformer oil?
Vacuum drying (requires shutdown) or online oil drying systems (operates continuously) are the best solutions for moisture removal.
