Environmental factors such as humidity, pollution, temperature fluctuations, and UV exposure can significantly impact the performance of transformer bushings. High humidity can lead to moisture ingress, which degrades insulation and reduces dielectric strength. Pollution, particularly in industrial or coastal areas, can cause contamination on the surface of bushings, leading to tracking and electrical discharges. Extreme temperatures can cause thermal expansion and contraction, stressing the bushing materials. Regular cleaning, monitoring, and maintenance are essential to protect bushings from environmental degradation.
