The main base for obtaining FR3 is vegetable oil with special additives of natural origin. Fireproof properties of this dielectric fluid are causedRead More
Heating OilHeating oil is obtained from diesel fractions of direct distillation and of secondary origins. Quite often there is confusion when heating oil is called “diesel oil” and vice versa. In fact, there are certain differences. Firstly, heating oil is slightly heavier than diesel oil by its fractional composition, and, secondly, heating oil does not haveRead More
Drawing of Transformer Oil Samples Sampling of transformer oil is quite an important stage in the process of diagnosing of oil-filled equipment current state. Today there are techniques that allow to make a conclusion about the need for repairs on the basis of sample analysis. It is necessary to choose dry weather when drawing samples from electric devices of outdoorRead More
What Is Waste Oil Processing?We most often hear about environmental issues in the context of production and transportation of crude oil. Its release to the environment can lead to soil degradation, water and atmosphere pollution. Due to great publicity certain steps are taken to address these problems, but the dangers of waste petroleum oil are not always spoken aboutRead More
Transformer Oil Breakdown Transformer oil is the main dielectric liquid widely used in many electrical devices. It is most often used to improve dielectric strength and cooling of windings in power transformers and other systems. Dielectric strength is a major characteristic of transformer oil. Typically, the minimum possible value is strictly regulated by the electric equipment operation rules.Read More
What to do with waste engine oil? Regular changing of motor oil is the harsh reality for modern automobiles. This operation can be performed at special service stations; however, many drivers prefer to do it on their own. It is not difficult, but it is associated with certain inconveniences, including the problem of waste oil disposal. A car owner who does notRead More
WETEX International Exhibition in Dubai October 4-6, Dubai (UAE) hosted the 18th WETEX 2016 international exhibition, which presented the latest water treatment technologies, energy technologies, and developments in environmental protection. The event has been organized by Dubai Electricity and Water Authority (DEWA) since 1999. Now WETEX is one of the leading exhibitions which gathers representatives of the energy sector fromRead More
Transformer Oil Analysis To determine the primary parameters of oil quality and performance, transformer oil must be carefully analyzed. The parameters must meet the requirements of various regulatory documentation. If the results of the analysis are not favorable, the oil must be either changed or purified. According to the quality and purity of transformer oil, it can beRead More
National Standards or Wikipedia: Buying Industrial Oil Industrial oil is distilled from crude oil. These oils have relatively low viscosity, about 5-50 cSt at 50C. In everyday life and in the industry, these oils are used for lubrication in friction parts of machines, fans, pumps, textile machinery or as hydraulic fluids, as well as a base for production of grease. Hydraulically drivenRead More
