What services do transformer oil companies provide to utilities and industry?

Beyond supplying oil, many companies provide condition assessment programs, sampling kits and training, lab testing, and on site treatment services such as filtration, dehydration, degassing, and sometimes full oil regeneration. They may support retrofill projects, contamination remediation, and environmental compliance such as spill planning and waste documentation. Some also offer online monitoring solutions like moisture sensors and DGA monitors through partners. The value is in combining product supply with lifecycle services that reduce failures and extend transformer life.
