What is a transformer oil processing rig used for in power transformers?

A transformer oil processing rig is used for the purification and maintenance of transformer oil in power transformers. This equipment removes impurities, moisture, and gases from the oil, ensuring optimal electrical insulation and cooling properties. By maintaining the quality of transformer oil, the processing rig helps extend the lifespan of power transformers and enhances their operational efficiency, ultimately contributing to the reliability of the electrical grid.
