YS ENGINEERING SOLUTION performs Transformer Oil Dehydration to remove harmful moisture from the insulating fluid, a critical process for maintaining Transformer health and longevity. Moisture contamination significantly reduces the oil's dielectric strength and accelerates the degradation of the solid paper insulation. This service typically involves connecting a specialized high-vacuum filtration or purification plant to the live or de-energized transformer. The oil is heated to lower the boiling point of water, and then circulated through the vacuum chamber where moisture and dissolved gases flash into vapor and are extracted, often achieving a very low final water content, such as 5 ppm or better. This vacuum dehydration and degasification process restores the oil's insulating properties, reducing the risk of internal electrical faults and ensuring reliable operation.
