A representative sample of the oil shall be examined in 100 mm thick layer at 27°C The oil shall be clear and transparent & free from suspended matter or sediment Transparent, clear and light: Density @ 29.5°C: IS : 1448 (P-16)-0.89: 0.840 g/cm 3: Kinematic Viscosity @ 27°C, cSt: IS : 1448 (P-25)-27: 12.4 cSt ensures that the temperature (of the oil) must fall to -20oC before the density of the oil would exceed that of ice'. EDF Energy approached us to fill two new gen transformers within their power station in Heysham. 2 Table 1: Mineral-Oil Based Transformer Oil Constituents Mineral Oil: Nytro Libra SAFETY DATA SHEET Issued: March 2003 Manufacturer: Nynas AB Emergency Tel: +46-8-33 70 43 . Otherwise the transformers will not be able to be properly cooled, and switches can break arc. Transformer oil, a type of insulating and cooling oil used in transformers and other electrical equipment, needs to be tested periodically to ensure that it is still fit for purpose. After the anti-oxidation additives have become depleted over time and through extended use, the oil will oxidize at a rate close to the rate of oxidation in an “uninhibited” base oil. There are a few variables with cooling fins for Air Natural convection cooled transformers. Naphthyl or cycloparaffins 60-70 % Viscosity is also one of the most important properties of the oil used in transformers. Transformer oil inhibited with Ionol usually creates a pronounced induction period which is good for the service life of the oil. Fresh oil should solidify at a temperature no greater than a pour point temperature of -45°C/-49°F. Optimal kinetic viscosity of the oil at 20 ̊C is about 28-30×10-6 m2/second. Find here online price details of companies selling Transformer Oil. Rates of breakdown voltage (BDV), depending on the operating voltage of the equipment, must be equal (kV). It must therefore have high dielectric strength, thermal conductivity, and chemical stability, and must keep these properties when held at high temperatures for extended periods. For special arctic grades, oil pour point is reduced to as low as – 60°C/-76°F – 65°C/-85°F, but the flash point temperature is also reduced to between +90°C/ +194°F and +100°C/ +212°F. Some of the main characteristics of transformer insulating oil are as follows:  Oil is a fuel, biodegradable, practically non-toxic, and does not cause damage to the ozone. The specific density of transformer oil will vary based on the manufacturer and region or location where the oil will be primarily used. Appearance: – The color of the oil must be clear and transparent. I digitized one design for an example into a spreadsheet. The J&P Transformer Book states that 'a limit of 895 kg/m3 at 20oC ensures that the temperature (of the oil) must fall to -20oC before the density of the oil would exceed that of ice' -thus ensuring that if ice forms, then it would remain at the bottom of the tank. Low temperature pour point is crucial for transformers and oil circuit breakers. 1.2 Scope.
