Single-Phase Transformer Single-phase transformer may be connected to obtain three-phase power. These are found at many Reclamation facilities, at shops, offices, and warehouses. ANSI standard connections are illustrated below in the following figures. There are other angular displacements that will work, but are seldom used. Do not attempt to connect single-phase units together in anyRead More
Alternative fuels appeared due to several factors. First, the countries with limited mineral reserves were searching to reduce their fuel dependence from foreign suppliers. Secondly, alternative fuels were considered more environmentally friendly than traditional fuels. Therefore, a biodiesel production was reasonably thought as a way to solve both problems. Biodiesel is a liquid fuel thatRead More
The engineering department of our company developed a new design of bitumen plant USB-3 with a capacity of 6 m3 / h. This type of equipment is very popular, due to the wide range of bitumen applications (roofing and waterproofing, road works, pipeline protection, lining of canals, etc.). It improves the properties of bitumen afterRead More
Transformer oil is widely used as coolant, insulator and suppressor of the arc in electrical devices. The composition of transformer oil includes naphthenes, paraffins and aromatic hydrocarbons. The mass fraction of other components, as a rule, does not exceed 4-5% (for a fresh product). Transformer oil operating performance Performance of transformer oil is evaluated byRead More
In late August in Accra (Ghana), GlobeCore team has completed commissioning of a UVB-10PK complex and provided training to service personnel. A UVB-10PK bitumen complex is a comprehensive solution to road construction facilities. it is capable of the following important functions: bitumen input; preparation of bitumen for further use; production of all bitumen emulsionRead More
The commissioning was scheduled on 5-8 of August in Jizan (Saudi Arabia) where GlobeCore employees started up the CMM-2-2 plant. The unit is set in a container, mounted on a single axle trailer and can operate in the following modes: Heating and filtration of oil; Thermal vacuum drying of oil; Vacuum treatment of other equipment.Read More
Three-Phase Transformer There are main different types of oil transformers, that we can discuss. Figures below show principles of single-phase and three-phase transformer. We can also look at special technological devises and methods, that can optimize and improve oil transformers. Three-phase power is attainable with one three-phase transformer, which is constructed with three single-phase unitsRead More
Power transformers are the most important components of an electrical grid. Transformers designs differ by the cooling and electrical insulation systems used. There are dry transformers and oil-immersed transformers. Most of transformers in service are oil-immersed. Their tank, containing the core, is filled with oil. The oil removes heat and ensures dielectric strength of insulation.Read More
Oil Treatment Hydraulic equipment, its maintenance or repair is not cheap. It is therefore recommended to develop and implement preventive maintenance program involving regular cleaning of hydraulic oil. Where do your money go? The largest operating costs of a hydraulic system are related to the following: oil change; parts replacement; equipment repair. Oil change involvesRead More
Oil Recovery To date, oil recovery occupies an important place in the environmental policy of every country. Petroleum products contaminated with various impurities (metal particles, water, dirt, oxidation products, etc.) significantly deteriorate and must be collected and recovered. Oil recovery is re-use of oil, both for its original and other purposes. Below is the analysisRead More
In today’s technologically advanced world, the proper handling of waste materials has become more critical than ever. Oil reclamation plays a pivotal role in this context, addressing the challenges posed by used and waste oils. Industrial oils, after serving their purpose, often become contaminants if not handled correctly. Unfortunately, in many countries, waste oil isRead More
Almost a year ago, GlobeCore organized presentations of its equipment in Zimbabwe (Harare). Unfortunately, not all interested industry representatives of this country were able to attend the event. Therefore, it was decided to hold a series of presentations. This time they took place on June 8 in the second largest city of Zimbabwe – Bulawayo.Read More
May 31 this year, GlobeCore engineers successfully completed the commissioning in Helsinki (Finland). CMM-4/7 unit is there to stay and work This equipment is designed for cleaning insulating oils with a viscosity below 70 cSt at 50 ° C from mechanical impurities, water and gases. The unit can be used during operation, installation and repairRead More
Sudden Pressure Relay Internal arcing in an oil-filled power transformer can instantly vaporize surrounding oil, generating gas pressures that can cause catastrophic failure, rupture the tank, and spread flaming oil over a large area. This can damage or destroy other equipment, in addition to the transformer, and present extreme hazards to workers. The relay isRead More
In May, more of GlobeCore equipment was commissioned in Gaborone (Botswana). At this time two transformer oil regeneration plants CMM-12R and CMM-4/7 were installed and commissioned In its design, CMM-12R is a multifunctional complex that carries out both processing of insulating oils and maintenance of transformers. The main distinguishing feature of this equipment is –Read More
May 13, a GlobeCore CMM-4/7 unit started its work in Lahore (Pakistan). One of the local Pakistani companies that is engaged in installation, maintenance and repair works of power transformers, uses a CMM-4/7 unit for servicing their transformers. This unit can perform heating, drying, cleaning and degassing of the entire volume of transformer oil. ThisRead More
During 2 days, May 3-4 in Quito (Ecuador), GlobeCore held a seminar presenting its equipment The event was attended by representatives of the electricity industry from many countries, including Peru, Bolivia, Argentina, Colombia, Costa Rica and El Salvador. The seminar covered the following questions: General information about GlobeCore; Modern technologies in cleaning and regeneration ofRead More
April 23 – 27, 2017 in Jeddah (Saudi Arabia), GlobeCore engineers carried out an effective commissioning of the CMM-0,6 unit. This equipment is ideal for organizations that have oil-filled equipment and requires their insulating oil cleaned from mechanical impurities, water and gases with processing rate 158 gal / h. The CMM-0,6 unit circulates the oilRead More
