Oil Handling, Processing, and Analysis.
Our company provides on-site oil collection services for transformers and transformer components, including HV bushings. Samples are analyzed at an accredited laboratory using the latest technology and procedures for transformer liquid testing covering Mineral, Silicon, and R Temp dielectric fluid. Each sample is tested and results are interpreted in accordance with guidelines published by the Institute of Electrical and Electronics Engineers (IEEE) for dissolved gases, total combustible gases, dielectric breakdown, power factor, and general chemistry. TSI then delivers to the customer a detailed report of the testing results, our interpretation of the results and recommendations for transformer maintenance or service corresponding with the result values, Oil Filtration Processing is performed to remove moisture, particulate, and gaseous contaminants by pumping oil through a vacuum filtration system. Vacuum Oil Processing is also used to ensure that all moisture is completely removed from the transformer during installation. We use Fuller’s Earth Filtration equipment to remove acids and sludge. This process also improves Interfacial Tension (IFT), power factor, neutral number, and color
