How does transformer oil dehydration improve the quality and performance of silicone oil?

Transformer oil dehydration removes moisture from silicone oil, which is critical because even small amounts of water can significantly reduce dielectric strength and promote electrical discharges. By extracting moisture through vacuum dehydration or other drying methods, the oil’s insulating properties are restored and maintained. This process enhances transformer reliability, prevents corrosion of internal components, and extends the service life of both the oil and the transformer. Dehydration is a vital part of oil maintenance, ensuring optimal performance and safety.
