Any transformer oil, even very well purified, contains some amount of naphthenic acids. These substances are part of any crude oil. Acids, in certain concentration, can damage the construction materials of a transformer. If the oil also contains water, the so called metallic soap forms. These substances accelerate oil oxidation. They gradually accumulate in theRead More
Transformer oil is intended for insulation of energized parts of power transformers from deenergized elements, as well as for heat transfer to cooling systems. This product is used in many transformers, although some may also use the so-called synthetic oil. There are also transformers operating without oil. Transformer oil is produced by purification of crudeRead More
Transformer oil is a special type of fluid which is used to fill power transformers. This product is obtained from petroleum distillates by application of selective, phenolic-alkaline and acid cleaning processes, as well as hydrocracking. Quality and characteristics of transformer oil has a huge impact on the service life of a transformer. Let us formulateRead More
Filtration, despite rapid development of science and technology, is still an important part of industrial fluid purification. A filter predominantly separates solids and water. Filtration is a common process, applied alone or in combination with other approaches. It all depends on the purity requirements and the initial composition of contaminants. The effectiveness of filtration isRead More

On 25 – 28 September, the Global Wind Summit 2018 was held in Hamburg, Germany. This is the biggest event in alternative energy source industry. Global Wind Summit-2018 included the WindEnergy Hamburg expo and WindEnergy Hamburg conference. Wind power generation companies were able to discuss the problems of the industry and see the latest developmentsRead More
The corrosive sulfur removal problem with transformer oil is widely known. Corrosive sulfur is the cause of contact disruption, forms deposits on copper and silver surfaces and interferes with the operation of winding winding and oil-filled switches. How corrosive sulfur appears in transformer oil The most natural origin of sulfur and sulfur compounds in transformerRead More
Energetab, the largest exhibition of modern energy equipment and technologies in Poland was held in Bielsko-Biala on 11-13 September 2018. This year’s exhibition included 712 companies over more than 35 000 m2 of exhibition floor. Among other exhibitors, GlobeCore presented two of its units: the CMM-0.6 and the UVR-L (laboratory). The СММ-0.6 is a compactRead More
The new issue of the Cement Americas Magazine came out in September 2018. The magazine published an article by Frank May, GlobeCore service engineer, titles The Promising Application of Vortex Layer Devices with Ferromagnetic Elements for Cement Improvement. The article discusses one of the main reasons for cement deterioration which increases cement consumption and includesRead More
The idea for mixing several components is usually to make a new product with new properties and characteristics. In many cases the task is as simple as using a regular mechanical agitator with an electric drive. However, more often than not, we deal with components which mix poorly, in which case a mechanical mixer isRead More
In the middle of August 2018, yet another product was commissioned: a CMM-4 unit, which was tested at one of the local hydropower plants. The main purpose of this equipment is purification of transformer oil. The unit removes solid particles, water and gas from the insulation fluid. Besides, the CMM-4 can heat electrical equipment withRead More
Before we go for an in depth discussion of oil purification, let us look at the history and development of lubrication materials. It is impossible to say for certain, when a lubrication material first came into use. It probably happened about the time when humans started using tools. Ancient Egyptians used olive oil to reduceRead More
This summer, GlobeCore was contracted to change the oil in the gearbox of an FL2500 wind turbine by Fuhrländer Windtechnology LLC. The analysis of the Mobil XMP 320 oil samples taken from the gearbox of the 2.5 MW FL2500 wind turbine (100 meter mast height) indicated the need for urgent oil change, which was performedRead More
