What is the process of dehydration of transformer oil in India?

The process of dehydration of transformer oil in India typically involves the use of vacuum dehydration systems. This method removes moisture and dissolved gases from the transformer oil, enhancing its dielectric strength and overall performance. The oil is heated and subjected to a vacuum, allowing water and gases to evaporate. This process is crucial for maintaining the reliability and longevity of power transformers, ensuring optimal operation in the electrical grid.
