Vibration Control at GlobeCore

Solutions,

GlobeCore is one of the leading manufacturers and suppliers of industrial equipment designed for use in the road building (road bitumen emulsion and modified bitumen production) and electricity industries (power transformer oil reclamation and oil purification).

It is impossible to take the lead in any kind of activity without the full consideration of the needs of the customer.  Today, sales of GlobeCore equipment covers more than 70 countries located all over the world.

During the transportation and delivery of industrial equipment, equipment is exposed to many negative factors, among which a special place belongs to harsh vibration.  Vibrations are essentially mechanical oscillations transmitted from the source of the vibration to the industrial equipment.  If the delivery to the Customer is done by air, the vibration sources may come from the rotation of high speed rotors found in jet engines and propellers, and from air vortices and the pulsations from turbulent airflow.

Vibration can also take place when industrial equipment is transported by sea.  Most often it is caused by the blows of waves against the hull of the transport vessel, but the operation of the propeller, internal combustion engines, turbines, and electric motors can cause vibrations.  Transporting by road is also not free from vibrations that can harm industrial equipment.

When designing and manufacturing industrial equipment, vibration protection and testing are integral parts of the quality control program.  A good comprehensive testing program will also include temperature tests and tests for moisture resistance.  In order to ensure long term product quality and durability,  GlobeCore’s units are exposed to a certain level of vibration in accordance with manufacturing and testing procedures defined by strict international standards.

In order to create certain types of vibration, GlobeCore uses special activators known as shakers that convert electrical signals into mechanical motion.  The shakers are capable of maintaining the vibrations at the desired vibration levels for the full duration of the testing process.

Before and after the testing, critical measurements are taken that include:

  • airtightness;
  • productivity;
  • pressure at the sensors;
  • noise level;

After the testing is completed, GlobeCore technicians determine whether the equipment is fit for sale and can be certified as meeting all operational requirements.  The conduct of vibration testing helps ensure the full compliance of GlobeCore’s products to their intended purpose.  Customer confidence and satisfaction is one of the main priorities of our Company.

Transformer Oil Processing Plants

Solutions,

Oil derivatives account for a significant share of toxic waste produced by modern industrial facilities. These materials are a cause of water, soil and air pollution.

Among the main producers of waste oil products are the electrical industry, chemical industry, metallurgical industry, and oil processing industry facilities.  In the environment, these substances cannot be rendered harmless by natural processes as they are impervious to such processes as biodegradation, oxidation and chemical reactions.  These toxic substances cause irreparable damage to living organisms while polluting the soil, water and air.  Recent studies by the U. S. FDA also suggest that waste oil may cause cancer and birth defects.

Like other forms of waste oil, transformer oil is one of the most hazardous pollutants.  This is mostly due to the polychlorinated biphenyls present in the oil.  These chemicals are resistant to hydrolysis and biodegradation in water, and can form dioxins in the process of photolysis, which are even more toxic.  Even one time contamination of bottom sediment by PCBs causes long term local contamination in water.  Processing of transformer oil therefore, must be one of the mandatory measures for protection of the environment against used oil products.

In practice, used oil can be disposed of, or regenerated.  Both processes can be divided into two subtasks.  The first is the organization of an oil collection infrastructure.  The second is development of regeneration technologies that, are environmentally safe and highly efficient.

This second objective has been successfully achieved by the transformer oil purification systems manufactured by GlobeCore.  GlobeCore equipment not only purifies of used transformer oil, but it also to restores the oil’s performance to its orginal specifications.  Once processed with GlobeCore’s high vacuum degassing and regeneration equipment, used transformer oil can continue to be used in transformers performing as insulator and as a heat transfer medium.

GlobeCore’s CMM-R units provide electric transmission companies with a comprehensive oil processing solution to dielectric oil contamination problems.  GlobeCore oil regeneration systems consist of oil degassing/purificartion and oil regeneration sections.  The units are designed for mobility and can be towed from site to site by truck.

Operation of the units is managed by a microcontroller with a touch screen panel.  CMM-R units operate according to pre-programmed process for eachmode of operation and require almost no operator interaction.

The units are installed inside a metal container that is placed on a semi-trailer or a standard container carrier.  The container is equipped with ventilation, lighting, operator/cpmtrol room and a compartment for tools and accessories.

The process of transformer oil purification involves connection of the regeneration and degassing sections of the CMM-R unit to the transformer.  When a CMM-R unit is connected to the transformer, oil processing can be started.  The oil is heated, filtered and degassed.  The oil then flows into the regeneration section.  Once regenerated, the oil goes back into the vacuum chamber of the degassing unit where gas and moisture are removed.  The final step is micro-filtration before being returned to the transformer.

When the adsorbent of the regeneration section of the CMM-R becomes saturated by contaminants, the plant automatically switches from oil processing mode to sorbent reactivation mode.  During the sorbent reactivation process, oil  continues to be processed in the degassing mode.  After the sorbent has been reactivated, the system automatically switches back to oil regeneration mode.

The GlobeCore regeneration process therefore, not only to purifies contaminated transformer oil, but it also restores the oil back to the original new like performance specifications.  The GlobeCore Process is designed to facilitate significant service life extension of dielectric insulating oils and greatly improve oil-filled equipment reliability.  At the same time, usedoil released into the environment is eliminated and need to buy new oil significantly reduced.

Explosion Proof Oil Regeneration Unit

Solutions,

Used oil is a rather hazardous substance that cannot be biologically degraded under natural conditions.  Most oil products will become a source of air, water and soil pollution if not disposed of properly.  Just one liter of used oil can pollute more than a thousand liters of water.

Waste oils, accumulated in the environment, disrupt whole populations of animals, birds and fish. They also have harmful effects on the human body as well.  Despite the need for more detailed research, today there is data confirming the connection between lung cancer and waste oil for humans whose work is related to handling waste oil.

This makes the problem of collection and disposal or recycling of used oil a very pressing one and requires quick and efficient solutions.  At this time, there are several methods of handling waste oil:

  • Restoration on site.  Harmful contaminants are extracted from the oil which makes it possible to reuse the oil.  This approach effectively extends the service life of the oil even if it does not restore the oil to as good as new condition;
  • Shipping the used oil for processing to an oil refinery.  In this case, the waste oil is used as a raw material to make other oil products;
  • Burning.  This method of disposal generates heat and energy for various processes. Water and some harmful contaminants must first be removed from the oil.  Unlike reusing the oil, burning, obviously, works only one time since the used oil is fully consumed by the burning process;
  • Regeneration. Oil regeneration is a process of restoring the oil’s performance specification to a good as new condition.  This process allows the reuse of the oil and, in theory, giving the oil an infinite service life.

Regeneration is the preferred way of dealing with used oil.  It requires only a third of the energy used to refine crude oil into lubrication oil.  Besides reducing energy consumption, making one liter of high quality oil requires 67.2 liters of crude oil and only 1.6 liters of used oil thereby preserving precious natual resources.

GlobeCore offers a wide range of equipment for purification and regeneration of transformer oil, industrial oil, turbine oil, transmission fluid, and many other types of oil used in various industries. The two main features of GlobeCore’s regeneration machines is versatility combined with many design options.  These include explosion proof designs that include various engineering solutions to protect against fire and explosion.  The explosion proof features allows GlobeCore machines to be used in facilities such as nuclear power plants, hydropower plants, oil refineries and other inherently dangerous industrial work sites.

Using the GlobeCore Process will extend the service life of mineral oils and the equipment the oil is used in significantly.  Your company will benefit additionally by reducing the amount of new oil purchaces and elminating the need to dispose of used oil.  You will be able to reduce or eliminate the amount of stored waste oil thereby decreasing the chance of environmental damage from used oil spillage.  The GlobeCore Process is the best and most comprehensive solution to the problem of used oil.

Equipment for Transformer Oil Analysis And Regeneration

Solutions, ,

Regular and proper maintenance of electric power generating equipment are two of the overriding priorities of today’s power industry.  Generally speaking, this kind of equipment includes many different kinds of units that have been designed for the distribution and transmission of electric power.   There has been however, a special value placed on electric power transformers that are used to change the voltage of alternating current(a/c) as well as transform electrical phases.

Transformers are operated in remote field locations as well as in cities and urban environments.  In the first case, maintenance of transformers can be difficult and/or troublesome since special equipment must be delivered to the remote places where the transformers are located.

This article will consider the peculiarities of analysis and reclamation of transformer oils in the field environment.

It is transformer oil that significantly helps to ensure the uninterrupted operation of an electric power transformer.  The dielectric insulating oil is necessary to transfer heat from the heated parts of a transformer, insulate  between the conducting parts and prevent the solid insulation from becoming contaminated with excess moisture.

Comprehensive research has shown that approximately one-third of all transformer oil is at risk due to many factors including a lack of timely preventive maintenance.  This means that during the transformer’s service life, the insulating oil is exposed to temperature extremes, different contaminants and mechanical impurities that can badly affect the condition of the oil’s performance characteristics.  The service life of insulating oil may be extended if regular scheduled maintenance, to include regeneration/reclamation, is timely performed.

A comprehensive analysis of transformer oil will allow you to determine whether oil needs servicing and/or regeneration (recycling).  As a rule, oil analysis is performed annually in special laboratories.

But what to do in the field environment when there are long time intervals between oil sampling and its analysing, which, in many cases, may be critical?

In this case, transformer oil analysis is made by special teams according to the approved schedule, using mobile control tools or mobile stand-alone laboratories.

Mobile stand-alone laboratories allow for performing a rapid analysis of transformer oils to determine the level of moisture and gasses, dielectric conductivity and tangent delta of the used transformer oil.

All necessary devices are mounted inside a cross-country truck, fitted with an alternating current (A/C) generator.

In general, the mobile laboratory normally consists of the following parts:

(1) moisture gauge, (2) gas content indicator, (3) dielectric factor indicator, and (4) tangent delta meter.

It is obvious that if oil’s performance characteristics are observed to have been degraded, it will be more convenient to perform a service on the transformer on site.  It is desirable therefore, to equip mobile laboratories with special transformer oil degassing and regeneration units.

GlobeCore is an industry leader in producing equipment for purification and restoration of fuel, industrial oil, turbine oil, dielectric insulating oil and other types of oil.

In the field environment, it is recommended to use GlobeCore equipment to perform maintenance on electric power transformers:

  • The GlobeCore CMM-R unit provides recycling (regeneration) of transformer oil through the use  of re-useable sorbent.  Transformer oil is passed through a Fuller’s Earth sorbent layer and then through a fine mesh filter.
  • The GlobeCore UVR units reclaim oil by means of a special regeneration powder.  The main difference between these two units is the type and amount of sorbent applied during the process of reclamation.  The Fuller’s earth in the CMM-R units may be used for 2-3 years with no need to dispose of it as hazardous waste.  The sorbent in the UVR equipment however, should be replaced after each processing cycle is completed.

The GlobeCore UVR line of equipment is highly versatile since it can process turbine oil, industrial oil, stove oil, transformer oils and diesel fuels.

How to Clean FR3 Dielectric Fluid

Solutions, ,

A fire-resistant dielectric, known as FR3 features a natural (organic) green substance, used in power transformers, reactors and oil circuit breakers.

The following is the list of benefits of FR3 fluid:

  • eco-friendliness (non toxic, no silicone, halogenes and benzenes).
  • complete biodegradation;
  • compatibility with other transformer oils;
  • fire explosion safety; and
  • good heat-exchanging and dielectric properties.

FR3 dielectric fluid may be used when repairing or remanufacturing serviceable transformers. The exceptions are devices that previously used silicone.  FR3 dielectric fluid consists of  vegetable oils and special additives that do not contain any  halogens, sulphur or other elements that can have an adverse effect on the environment. But, despite the natural composition, FR3 dielectric fluid is still subject to oxidation and aging.

It is known that proper recycling and purification and regeneration restores oil’s performance characteristics to the acceptable levels and extends the service life of the oil and the transformer.  When processing FR3 fluid, it is necessary to choose equipment that, on one hand, can provide a high-quality treatment of oil and, on the other hand, can process not only petroleum-based oils but also natural-based fluids like FR3.

Such versatile equipment will allow you to process different types of oils thereby reducing operating costs.

GlobeCore oil processing equipment has obtained a wide acceptance in more than 80 countries around the world.

11667442_804952062957881_5192054319660316997_nIn July, 2015, GlobeCore Clean Marine unit, designed to process dielectric fluids on offshore drilling platforms, was tested 250 kilometers from the Nigerian seacoast using FR3 fluid.  The results were impressive: GlobeCore equipment completely restored the performance characteristics of FR3 fluid which rendered it serviceable again.

Summing it up, it should be mentioned that GlobeCore always considers the wishes of its customers and can  customize equipment to meet the individual needs of each client.

Transformer Oil Recycling and Regeneration Unit for Offshore Drilling Platforms

Solutions, ,

The onshore deposits of oil and gas are depleting with each passing year and it prompts people to seek new energy sources.  Exploration and development of oil and gas from offshore deposits gives modern society the possibility to extend into the time when some other form of fuel will be able to replace oil and natural gas.

Offshore drilling is performed on special platforms, floating or semi-submerged drilling rigs.  The term “offshore drilling” was first used in 1869 when the project of a drilling rig for shallow-water operations was first patented in the USA.  Since that time, science has not remained idle.  So today we have mobile rigs that can be operated at the depth of between 300 meters and 3 kilometers. If the drilling is performed on these offshore platforms, they use special electrically-operated rigs that are powered by cable lines of 6 and 35 kW.  Single-motorized rigs are used when drilling from individual offshore platforms.  As a rule, floating semi-submerged platforms are equipped with diesel-electric drives to produce AC and DC current.

The number of machines, their capacity and the capacity of the driving engines of the main and additional units depend on the drilling depth and the sea depth.

An electric power transformer is an integral part of offshore drilling since it provides power for drilling platforms, converting the AC voltage into the voltage needed by the equipment it is servicing.  So, it is the electric power transformer that helps to determine the reliability and efficiency of the drilling rigs as well as the whole offshore drilling process.

Transformer oil in the power transformers is necessary to transfer heat and insulate the current-conducting parts from non-conducting parts.  During operations, insulating oil is exposed to a wide range of unfavourable factors that contribute to the degradation of its performance characteristics.  That is why oil needs reclamation on a timely basis to maintain its physical and chemical characteristics at the desired level.

When operated, drilling rigs are exposed to the risk of explosion.  The equipment used on offshore drilling platforms therefore, should come in an explosion-proof design.  This is also true for the equipment used for transformer oil reclamation.

Clean-MarineNigeriaGlobeCore is one of the leading manufacturers of oil purification and regeneration equipment. One of GlobeCore’s latest developments is the Clean Marine Unit specifically designed for transformer oil recycling/regeneration/reclamation on offshore drilling platforms. It is explosion proof and protected from saltwater moisture and corrosive materials.

The Clean Marine Unit is used to degas and purify transformer oil by removing mechanical impurities and by vacuumizing transformers in the offshore industry.

The GlobeCore Clean Marine may be operated in one of the following modes:

(1) transformer oil heating; (2) oil degassing; and (3) vacuumizing.

GlobeCore equipment, designed for offshore platforms, restores the performance characteristics of insulating oil, extends its service life and increases the reliability of electric power transformers.

Regeneration/Reclamation of Used Turbine Oils at Electric Power Stations

Solutions, , ,

The fact that sources of energy such as oil, gas, slate stone and coal are nonrenewable, prompts people to pay special attention to alternative sources of energy.  In particular, this means energy from water, wind and the sun.

Hydropower plants (HPPs) and pumped storage power plants (PSPP) occupy a special place in modern energy systems, ensuring uninterrupted power generation under the peak loads.

The obsolescence of equipment and electric power lines at hydropower plants causes problems with reliability and safety of the electric power supply.  But, this problem may be solved either by introducing new generating capacity, or extending the service life of the existing generating systems.

The purchase of new capacity requires considerable expenditures, that in the most cases, is unaffordable for hydropower plant operators.  It is therefore, reasonable to perform regular maintenance of equipment to prevent potential failures.  Much importance is placed on oil facilities that ensure uninterrupted and reliable operation of hydropower plants.  Such facilities include equipment, necessary for:

  • fresh oil collection;
  • fresh and waste oil storage;
  • oil purification, regeneration and drying (recycling); and
  • oil discharge from equipment in case of emergencies or equipment failures.

Hydropower plants may store lubricating oils, transformer oils, and compressor oils on site.

Turbine oils are used in turbine control systems that include oil pressure units, guide-vane servomotors, servomotors in runners, oil bearing, and thrust collars.  Turbine oils are used under very extreme conditions such as high temperatures with air and mechanical impurities present.

These unfavourable conditions result in the oil’s degradation.  That means that the viscosity and acid number increases, the flash temperature is reduced, and mechanical impurities and sludge appear.

Hydropower plants perform regular monitoring of physical and chemical characteristics of turbine oils.  Samples of turbine oil are taken and then analysed by well-trained staff in special chemical laboratories.  If the oil’s characteristics are observed to have been degraded, then the oil is replaced with fresh oil.  But, it requires great expense to buy new oil and dispose of the used oil.

Additionally, waste turbine oil is a hazardous material and its discharge into the environment may cause contamination of soil and water systems.  In most cases however, the degradation of the oil’s performance characteristics does not mean the end of oil’s service life.

Reclamation of used turbine oil is a desirable way to reduce operating costs, improve the operational reliability of hydropower stations, and provide an uninterrupted energy supply.

GlobeCore is one of the leading manufacturers of equipment for purification and reclamation of turbine oil, transformer oil, industrial oil, transmission fluid, and other types of oil.

GlobeCore reclamation/regeneration (recycling) technologies are distinguished through mobility, eco-friendliness, and cost effectiveness.

GlobeCore equipment ranges in capacity and allows a hydro power plant to choose the most optimal equipment to meet their needs.  Used turbine oil reclamation, performed using GlobeCore equipment, improves the performance characteristics of oil allowing the reclaimed oil to be placed back into service again.  It is therefore, very important to perform regular monitoring of oil’s condition to determine the degradation of its characteristics.

Reclamation/regeneration of used oil at hydropower plants will reduce the need to install additional used oil storage tanks and will save fuel that is required to deliver used oil to collection centers or disposal sites.

GlobeCore ensures a high-quality process in the reclamation of used turbine oil directly at hydropower plants.  If you are looking for solutions that will reduce your operating costs, then GlobeCore technology is the answer to your oil related preventive maintenance problems.

Transformer Oil Degassifier

Solutions,

In practical terms, transformer oil oxidation is caused not only by contact with atmospheric air but also by gases that become dissolved in the oil. Oxidation is not the only negative after-effect of this process.  Dissolved gases and gases, found in the solid transformer insulation, reduce the dielectric strength of the insultaion system made of both liquid and solid parts.  The oxidation is caused by the fact that occluded gas becomes the source for the development of unwanted electric charges.

The issues of oil degassing and transformer vacuumizing have taken on enormous importance since  transformers with a higher voltage became widely used in the electric transmission industry.  The rate of saturation of oil with gases is determined by the height of the oil column and the contact surface with gas.  The rate of the reversing the process depends on the same parameters.

Vibration may lead to the formation of bubbles in oil, caused by depression zones.  This tends to have an adverse effect on the insulating system’s reliability.  That is why vibration of energized transformers should be reduced to a minimum.  In practice, special units, called “columns” are used to perform vacuumizing.  There is a screen inside a column equipped with atomizers.

To provide the highest level of efficiency, these atomizers should have the largest possible area per unit of volume and the least possible resistance to the oil flow.  The most appropriate atomizers are considered to be a set of devices called “Raschig Rings.”  They are similar in appearance with rings, the diameter of which equals its height. Such rings may be made of different materials such as metal, porcelain, and ceramics.

In practical terms, electric utilities use GlobeCore CMM-R units for transformer oil degassing.  They are designed to remove gases, mechanical impurities and to heat up transformer oil found in transformers with a voltage of up to 1150 kW.  In addition, such equipment may also be used to heat up oil-filled electrical equipment and to dry and vacuum transformers.

The following are the parameters of processed oil:

  • gas content, %, no more than 0.1;
  • mass moisture content, g/t, no more than 5;
  • ISO 4406 purity class – 9.

Service Life Extension of High Voltage Equipment

Solutions,

GlobeCore transformer oil purification plants are designed to restore the properties of transformer oils and extend the service life of the oil filled equipment.

At the beginning of the 21st century, the main task of the electric power industry was to maintain electric equipment, the expected service life of which had expired.  This issue was at and remains at the top of problems faced by the electric power industry because of the limited financial resources to buy new equipment.

The progress of the electric power industry in the world’s industrialized countries reached its highest peak in 1970s and 1980s.  In the USA it was reached in 1974 when transformer capacity was increased to 180 gigavolts and amps.  By this time, the typical electrical equipment had served more than 40 years, exceeding its expected service life by more than 15 years on average.

The following is the list of common reasons for transformer breakdownsand failures:

  • deterioration of equipment, caused by some disadvantages that speed up the aging process;
  • accelerated aging of associated parts (inputs, parts of a cooling system);
  • dynamic instability of windings inthe case of short circuits;
  • damages of the main and longitudinal insulation usually caused by moisturization, contamination, and long term use without regeneration and purification; and
  • irreversible destruction of cellulose through neglect.

It should be mentioned that more than 80% of breakdowns may be avoided if timely preventive maintenance is performed on a scheduled basis in conjunction with an comprehensive oil analysis program.

The Concept of  Service Life Extension for your Electric Power Equipment

Maintenance of transformers, the expected service life of which has expired, is possible with a good preventive and corrective maintenance program.

The first stage consists in the evaluation of the actual condition of the equipment. It allows the equipment owners to determine whether a service life extension program is reasonable on a case by case basis.  If there are no irreparable damages that require the main components to be changed, then the measures to extend the service life  of a transformer should be taken.

The following is the detailed list of  work performed:

  • to remove the potential defects that directly affect the equipments reliability and accelerates the aging process;
  • remove moisture, gasses, mechanical impurities and the products of aging, including those, being absorbed by the cellulose insulation;
  • improve potentially unreliable parts in order to hamper the process of aging;
  • reduce operational costs through the introduction of a monitoring system or optimization of a cooling system; and
  • regenerate/reclaim used transformer oil currently in operation in the transformer.

You may have noticed that the majority of defects are connected with reversible changes in the insulating system caused by moisture, contamination by mechanical impurities, and gases.  In fact, the service life of oil filled equipment may be extended by removal of moisture and water, removal of mechanical impurities, degassing and complete oil restoration/reclamation.

Additionally, these measures are considered to be the most effective ones.  GlobeCore  offers a wide range of mobile transformer oil purification plants.  They are designed to restore oils to the like new condition that have minor deviations from the rated values as well as waste oils unsuitable for further use.  On one hand, such an approach provides for the service life extension of high voltage equipment by improving the condition of the equipment’s insulating system.  On the other hand, it helps to save money on new oil purchases and by avoiding waste oil disposal costs.  Some mobile oil plants, in particular the GlobeCore CMM-R line, are designed to process oil even on energized transformers.  Proper and timely preventive maintenance will reduce equipment downtime and unscheduled repairs.

Oil Regeneration by Fuller’s Earth

Solutions,

Fuller’s Earth is a clay like substance found all over the world.  Historically, Fuller’s earth was first applied to treat cloth therefore, it may also be called a “smectis” whcih has also been called “soap rock.”  Practical use of this substance prevailed up to the 1930-ies.

In the first half of the 20th century, researchers focused on  improving the oil refining process.  An American scholar, David T. Day, was the first researcher to publish the fact that oil fractions, passing through Fuller’s Earth, are separated into parts that differ in color, viscosity, specific weight and other properties.  As a result of day’s findings, many scholars began to pay attention to this characteristic of Fuller’s earth.  For example, the researcher,  Kaufmann, filtered concentrated cylinder oil using Fuller’s Earth as an adsorbent.  He observed that the first portion of the product was characterized by lower density and viscosity, as well as a lower ASTM coke number.

All subsequent factions had properties similar to the properties of the source raw material. In 1930, in France, the Houdry process that converted lignite into gasoline, was found to be inefficient.  The previous studies had shown however, that the process can be improved by using Fuller’s earth.  If  Fuller’s Earth is appled as an adsorbent, the characteristics of the oil product are changed due to the selective adsorption of nitrogen, nitrous and oxygen containing compounds and polycyclic aromatic hydrocarbons.  The developers and producers of oil processing equipment have taken this fact into account when designing modern oil processing machines.

It should be noted that oil regeneration is a full restoration of the performance characteristics of oils which ordinarily are unfit for further use because of significant deterioration of their physical and chemical properties.  Oil can be processed either by percolation (granulated Fuller’s earth) or by contact treatment (fine-grained Fuller’s earth).

GlobeCore has developed the CMM-R line of regeneration units that feature a modern and self cleaning Fuller’s Earth system.  A unique feature of this equipment is that Fuller’s Earth can be reactivated directly in the equipment.  First, it improves the regeneration process and reduces the scheduled and unscheduled downtime of the equipment.  Second, it allows for considerable cost saving since there is no need to buy new Fuller’s earth and dispose of the used Fuller’s earth during and after each processing job.

The use of GlobeCore CMM-R units restores the dielectric strength and chemical composition of dielectric transformer insulating oil.  When using the GlobeCore Process, considerable sums of money are saved and the reliability and efficiency of oil-filled equipment is increased.

The GlobeCore Process regenerates oil with no discharge of oil from the transformer.  When connected, the CMM-R systems form a closed path where

oil that needs restoration flows into the unit and the processed oil  flows back to the transformer in a continuous loop.  In this way, contaminants are washed out from the solid insulation.

Additionally, oil may be regenerated on energized transformers allowing an uninterrupted supply of electricity to consumers.
