Transformer Oil Analysis Report 2016 Client : ABC Singapore Pte Ltd Location : 111 ABC Road. Singapore 123456 Sample Received : 02 Samples Report Reference Number : S00116M Date Sampled : Monday, March 7, 2016
The recommended frequency of transformer oil analysis is dependent on both the voltage and power. The chart on the left can serve as a guideline but does not take into consideration the transformer’s operating environment. If results from a periodic test raise a red flag, the frequency should be increased. Transformer oil and insulating oil tests, from our Total Quality Experts. 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. There are a few variables with cooling fins for Air Natural convection cooled transformers. The ratio of weight of oil to kVA rating follows a power series. I digitized one design for an example into a spreadsheet. I estimate 9 kg/kVA at 300kVA or

Dissolved gas analysis (DGA) is the study of dissolved gases in transformer oil. It is also referred to as a DGA test. It is also referred to as a DGA test. Whenever a transformer undergoes abnormal thermal and electrical stresses, certain gases are produced due to the decomposition of the transformer oil. Analysis of dissolved gases in transformer dielectric oil is often the best method of detection certain problems that may eventually lead to failure of the transformer. All transformers generate different gases during normal operation. The detection and interpretation of certain key gases and gas quantity ratios allows the transformer The basis of modern oil analysis programs is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants, and additives in oil samples. Whatever an oil lab may need to measure, multi-elemental analysis is the core of an in-service oil analysis program. A 300kVA oil-filled transformer would contain 300 to 400 gallons of mineral oil. What is being used nowadays is type 2 mineral oil. If you want “high fire point” go with “Envirotemp” soy-based oil, then change the rating to KNAN.

Many manufacturers and insurance companies recommend annual testing of transformers for early detection of potential problems which is why we offer oil analysis as one of our many services. Tens of thousands of samples are tested each year for Dissolved Gases, PCB Content, Moisture, and more. Page 1 Transformer nameplate, identification name, oil and gas results and any notable comments and deficiencies. Pages 2&3 Graphs for all generated gases and chemical analysis tests. This provides a more visual idea of determining the trending of these gases. All limits are based upon standards widely accepted throughout the industry. The transformer oil market forecast is studied from 2014 to 2020. Industry analysis is conducted by following key product positioning and monitoring the top competitors within the market framework. The qualitative data in this report aims on market dynamics, transformer oil market trends, and developments.
