What is a silicone oil filtration unit, and how is it utilized in transformer maintenance?

A silicone oil filtration unit is specialized equipment designed to remove solid contaminants from transformer oil. During maintenance, the unit is connected to the transformer’s oil system, and the oil is circulated through it. The filtration unit employs multi-stage filters to capture particles of various sizes, preventing them from compromising the oil’s insulating properties. By maintaining oil cleanliness, the filtration unit helps prevent electrical discharges caused by particulate contamination, thereby enhancing transformer reliability and extending its service life.
