TSI has been an industry leader in transformer oil treatment since 1952. TSI has three truck-mounted oil purification systems that provide the following treatment of 10c mineral oil, cable oil, Rtemp, and bio-fluids:
Most transformers can be processed while energized provided there is adequate clearance from bushings and safe access to fill and drain valves.
TSI’s process uses inline moisture monitoring, on-site dielectric tests, and fluid quality tests for process control.
TSI also has portable equipment to degas and dehydrate silicone-filled transformers.
Vacuum Fills and On-Site Dry-Out
TSI’s vacuum fill process ensures that a new transformer is thoroughly dehydrated prior to being put into service. The steps in the vacuum fill process are:
