These precautions are necessary to ensure the transformer oil is protected against moisture and dirt. ��6�;mO�ᔈ������� The name mineral oil by itself is imprecise, having been used for many specific oils over the past few centuries. Physical Properties. 5) - Standard grade. ASTM D2502 describes how to obtain the mean molecular weight from viscosity measurements at 37.78 °C and 98.89 °C (100 °F and 210 °F). However, the production of mineral oil and rapeseed oil and their use in hydraulic fluid has been studied, as has the environmental impact of transformers. Some transformers, particularly indoor units, are filled with a synthetic fluid, such as silicon, R-temp, or Askarel (PCB fluid). 4.

Keywords: vegetable oil, mineral oil, power transformers, electrical charging tendency, flow electrification phenomenon 1. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Mineral oil varies in specific gravity from 0.818 to about 0.920, depending on how refined it is. This increases the possibilities for a longer transformer life with less maintenance. Oil is used to cool the transformer, because it also provides part of the electrical insulationbetween internal live parts, transformer oil must remain stable at high temperatures for an extended period. 1. The use of silicon oil has some better properties like, high flash point (low flammability) but they are very expensive and also non-biodegradable . From these, one can assess the environmental influence of the entire life cycle of mineral and vegetable transformer oils. 5 0 obj MIDEL 7131. is readily biodegradable, avoiding environmental damage should leakage occur and enabling reductions in containment measures.

Online calculator. In method of DGA and moisture test, the mineral oil sam-pling must be collected from the transformer with carefully espe-cially bubbles and contaminated during collected. The amount of oil used in a transformer depends on the size of the transformer. Transformer oil is used in oil-filled electrical power transformers to insulate , stop arcing and corona discharge , and to dissipate the heat of the transformer (i.e. Numerical analysis. The MIDEL range of ester transformer fluids delivers an array of distinct benefits when used in a power transformer or distribution unit. As per the manufacturer of the mineral oil-filled transformer, the rated TOT is 79.7 °C and the rated HST is 96.2 °C. Nytro 4000X is an insulating oil; T110 is a base oil; Nypar 315 and Nyflex 3150 are process oils; The given samples were provided by courtesy of Nynas AB, Sweden. A significant portion of the Oxygen is from atmosphere entering through the defects. 2. Transformer oil usually contains oxygen in addition to other gases. Engineering measures to reduce exposure: Mechanical ventilation and local exhaust will reduce exposure via the air. The big difference is in the density, which is about a factor of 1000 larger for liquids over air at atmospheric pressure. The liquid functions both as an electrical insulation and as a heat transfer fluid. Transformer Oil Description Castrol Insulating Oil is a pure mineral hydrocarbon oil, specially refined and blended from selected crudes. I guess it's a question of whether you take that over the non-conductivity.) Key words: Transformer mineral oil, lifetime, degradation, arrhenius law INTRODUCTION The mineral oil [1-4], with the main roles of insulating and cooling in power transformers, is similar to the blood in human body. Despite the variables that determine the density of the oil, the density number should not exceed 900 kg / m3 at a predetermined temperature of +20°C/+68°F. It is used in oil-filled transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers.Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant. In order to manufacture the transformers according to the required performance levels (dielectric characteristics, insulation and projected lifetime), specialized constructive changes were calculated and planned in … Also, natural ester oil transformer designs are more insulation intensive as the electrical stresses are present in the paper as opposed to mineral oil where the stresses are in the oil. Natural ester oil has a density and viscosity that is different to mineral oil. Experimental measurements of oil density versus temperature for the three esters and the mineral oil. Transformer oil is used to insulate the electrical power of a transformer and used to stop the direct contact of oxygen in the transformer. The TXplore service can be offered for mineral oil, ester fluids and silicone. Transformer Oil will be obtained by fractional distillation and subsequent treatment of crude oil. Environmentally safer than mineral oil, MIDEL eN 1215 has a pour point of -18°C and delivers excellent performance in non-free breathing transformers in temperate climates.

Formulas are taken from Russia's GOST R 8.610-2004. Two of the main characteristics of transformer oil are its viscosity and density. But, the simulated rated TOT is 80.6 °C and the simulated rated HST is 97 °C. Unlike competitive products formulated with naphthenic mineral oils, LUMINOL TR and TRi use Petro-Canada's ultra-pure severely hydrotreated isoparaffin base oils to deliver worry-free, corrosive sulphur-free performance in your transformer. It is of two types: Paraffin-based transformer oil and Naphtha-based transformer oil. 1.1 This specification covers unused mineral insulating oil of petroleum origin for use as an insulating and cooling medium in new and existing power and distribution electrical apparatus, such as transformers, regulators, reactors, circuit breakers, switchgear, and attendant equipment.
