- •
Degradation rate of mineral oil and natural ester oils are analyzed by varying the relative humidity of the air.
- •
Failure rate of oil samples are analyzed by using Weibull statistics method.
- •
Sunflower oil and Rapeseed oil performs better under all conditions compared to Mineral oil and have higher life time.
- •
This helps to improve the reliability of transformer and power distribution network in a greater extent.
