Transformer oil purification is essential for maintaining the performance and longevity of power transformers. Over time, transformer oil can become contaminated with moisture, dissolved gases, and solid particles, which degrade its insulating and cooling properties. Purification of transformer oil involves several steps: vacuum dehydration to remove moisture, filtration to eliminate solid particles, and degassing to extract dissolved gases. These contaminants, if left untreated, can lead to a decrease in dielectric strength, causing potential insulation failure and overheating in the transformer.
