What is an online transformer oil filtration system used for in power transformers?

An online transformer oil filtration system is used for in power transformers to continuously remove contaminants such as moisture, particulate matter, and dissolved gases from the transformer oil. This process enhances the dielectric strength and overall performance of the oil, prolonging the life of the transformer and ensuring reliable operation. By maintaining optimal oil quality, the system helps prevent failures and reduces maintenance costs associated with power transformers.
