What is the impact of moisture in oil transformer on its performance?

The impact of moisture in oil transformer on its performance is significant, as moisture can lead to reduced dielectric strength, increased conductivity, and accelerated aging of the insulation system. High moisture levels can cause the formation of acids and sludge, which degrade the oil quality and impair heat dissipation. Consequently, moisture in oil transformer can result in overheating, reduced efficiency, and ultimately, failure of the transformer. Regular monitoring and maintenance are essential to mitigate these effects.
