Transformer Oil Testing
Transformer oil and insulating oil tests.
Intertek's TransoilCHECK© program provides transformer oil and insulating oil analysis and testing on a global basis. The laboratories test for transformer oil purity, quality, and chemical composition. Transformer oil test methods include ASTM, BS, and other recognized transformer oil analysis testing procedures. Specific transformer oil test method availability will vary depending upon location. Please contact Intertek for more information.
Routine testing of transformer oils and insulating oils on a regular schedule is an accepted industry practice. General and physical tests are suggested twice a year, dissolved gas analysis once a year, and Furan testing every 2 years for transformers in operation at least 5 years. Samples are easily shipped to Intertek laboratories providing transformer oil analysis, on a global basis. Insulating oil and transformer oil testing labs are located in the United Kingdom, United Arab Emirates, Singapore, Mexico, Spain, and other locations. The labs test insulation oil samples from clients across the world.
