The Buchholz relay (figures 33 and 34) has two oil-filled chambers with floats and relays arranged vertically—one over the other. If high eddy currents, local overheating, or partial discharges occur within the tank, bubbles of resultant gas rise to the top of the tank. These bubbles rise through the pipe between the tank and theRead More
Transformer Bushings When bushings are new, they should be Doble tested as an acceptance test. Refer to the M4000 Doble test set instructions, the Doble Bushing Field Test Guide [9], and the manufacturer’s data for guidance on acceptable results. CAUTION: Do not test a bushing while it is in its wood shipping crate, or whileRead More
After 1 month of service and yearly, inspect the gas pressure control components. There is normally an adjustable, three-element, pressure control system for inert gas, which maintains a pressure range of 0.5 to 5 psi in the transformer tank. There is also a bleeder valve that exhausts gas to atmosphere when pressure exceeds relief pressureRead More
Mining Equipment Project Pumping out quarry waters At the end of 2014, GlobeCore completed a diesel pumping station project. This new piece of equipment is designed for pumping out quarry waters with a low level of solid particles. The diesel pumping station has been already successfully used at the ore-dressing and processing enterprises. The coolingRead More
Equipment at Hydroelectric Power Plant What is purification oil End of April GlobeCore delegation had a working visit to a hydroelectric power plant (HEPP), one of many that have GlobeCore filtration, purification and oil recycling plants for turbine oils, operating there over the past several years. Turbine oil is designed for lubrication of bearings, transmissionsRead More
Comparison of Silicone Oil and Mineral Oil Transformers Some general conclusions can be drawn by comparing silicone oil and mineral oil transformers. 1. All silicone oil-filled transformers will have a great deal more CO than normal mineral oil-filled transformers. CO can come from two sources—the oil itself and from degradation of paper insulation. If theRead More

The aim of the event was to present the latest developments in the field of purification and regeneration of waste oils. The representative of GlobeCore, Roman Gluschenko, delivered the report onRead More
In the beginning of April this year, in Shymkent, Kazakhstan, an annual international electric energy conference was held. Such events allow to demonstrate and discuss with specialists own developments in the field, as well as evaluate perspective developments by other companies. This conference could not be left unattended by GlobeCore.The company manager’s report focused onRead More
The Use of Fuller’s Earth in the Regeneration of Contaminated Transformer Oil Oil Regeneration machine Contemporary approaches to the regeneration of used/contaminated transformer oil will be examined in this article. It has been shown through research and real world field experience, that mobile oil reclamation equipment of the CMM-R type, manufactured by GlobeCore, is perfectly suited for thisRead More
Model Iney The “Frost” Model by GlobeCore is designed for vacuuming and drying the solid insulation of electric power transformers from 110 to 1100 kW. This equipment is used for maintaining the efficient operations of transformers. In order to ensure the initial trouble free operation of your electric power transformers, the use of the “Frost”Read More
Vacuum Model UVD-4, manufactured by GlobeCore, is used for topping off oil into high-voltage transformer bushings and circuit breakers. It is also used for preparing the transformer for its initial operation, degasing, storage and transporting to power plants, substations and other power and industrial plant locations. With the UVD-4 piston design, oil filling is performedRead More
Low Temperature Refrigeration Systems Production of new equipment has begun with GlobeCore’s low-temperature refrigeration units. These exciting new units are based on a two (2) stage design and are used for drying the windings inside electric power transformers. The drying takes place during de-pressurization and during service maintenance events. The machines can reduce working surfaceRead More
Turbine oil is used for lubrication of various components of steam and gas turbines, hydrocompressors, turbine pumps, hydro-turbines and similar equipment. Turbine oil can also be used as fluid in regulation systems.The oils can be natural or synthetic. The former are made from crude oil distillates after deep purification. The necessary properties are ensired byRead More
Breaking news! Our engineers have just developed and constructed a new degassing plant, the CMM-6D, which has been successfully tested and put into production. DEGASSING UNIT CMM-6D Degassing unit CMM-6D has been designed to clean electrical and turbine oils by removing mechanical impurities as well as water and gases using a thermal vacuum purification process.Read More
Industrial oils regeneration Long use of industrial and motor oil causes accumulation of oxidation products and other contaminants. Together these substances adversely affect oil performance, drastically reducing the oil’s quality. To avoid failures of costly equipment, old used oils should be changed with new. Old oil is collected for special regeneration processing. Such operations savesRead More
Used oil regeneration Transformer oils perform several functions. They operate as liquid insulation and heat dissipation medium in oil filled switches, transformers, power cables and high voltage capacitors. Besides, they also act as arc extinguisher. Transformer oil is made by purification of petroleum oils, made in turn from crude oil. The crude oil originates fromRead More
