What are oil filtration systems used for in transformer maintenance?

Oil filtration systems used in transformer maintenance serve to remove moisture, dissolved gases, and particulate contamination from insulating oil. These systems are critical for extending the life of power transformers, particularly in heavy industry and power distribution networks. Fluidex offers high-vacuum oil filtration systems with multi-stage filtration designed for both offline and online servicing. Their equipment helps maintain oil’s dielectric strength and prevents insulation breakdown, especially in environments with high humidity or thermal stress.
