    in reply to: How does oil bleaching differ from deodorization? #122722

    Oil bleaching removes color pigments, impurities, and trace metals from oils, while deodorization focuses on eliminating unpleasant odors and volatile compounds. Deodorization is typically done through steam distillation at high temperatures, whereas bleaching involves using adsorbents at moderate temperatures.

    Moisture is removed from wind turbine transformer oil using vacuum degassing systems. These systems apply a vacuum to the oil, causing the moisture to evaporate and be drawn out of the oil. In some cases, oil drying units or adsorbent materials are used to further reduce moisture levels. Removing moisture is essential for preserving the oil’s dielectric strength and preventing electrical breakdowns.

    When selecting Hydraulic Oil Purifier Systems for industrial use, it is essential to consider several key features to ensure optimal performance and compatibility with existing systems.

    Transformer Oil Moisture Content has a profound impact on the overall health and functionality of a transformer. High moisture levels in the oil significantly reduce its dielectric strength, increasing the risk of electrical discharges and insulation failures. This can lead to short circuits, reduced transformer efficiency, and even catastrophic failures that disrupt power distribution. Moisture also accelerates the chemical degradation of the oil, resulting in the formation of acids and sludge that corrode internal components such as windings and core laminations. This corrosion weakens the structural integrity of the transformer, leading to increased maintenance costs and shortened operational lifespan. Additionally, moisture in the oil impairs its cooling properties, causing overheating and thermal stress on the transformer’s components. By maintaining low moisture content through effective drying processes, the insulating and cooling functions of the oil are preserved, ensuring reliable and efficient transformer performance while extending its service life.

    Silicone oil offers safety advantages due to its high flash point and low flammability, significantly reducing fire risk compared to mineral oils.
