When Drying Transformers After Repairs, a systematic procedure is followed to ensure that moisture and contaminants introduced during the repair process are effectively removed, guaranteeing optimal transformer performance. The process begins with inspecting the transformer to identify any areas that may have been exposed to moisture or contaminants during repairs. Pre-heating the transformer oil is then conducted to reduce its viscosity, facilitating more efficient moisture removal. The Air Drying System is activated, circulating dry, heated air through the oil to absorb and evaporate moisture. Filtration systems are employed to remove any particulate matter or debris that may have entered the oil during repairs. Vacuum dehydration techniques may be utilized to further extract dissolved gases and moisture, ensuring thorough drying. Throughout the drying process, monitoring tools track moisture levels, temperature, and humidity to ensure that drying objectives are met. Quality tests are performed post-drying to verify the oil’s dielectric strength and purity. Finally, documentation of the drying process and any adjustments made ensures that records are maintained for future reference, supporting the transformer’s long-term reliability and performance.
