<\/p>\n<\/p>\n
Industry is always looking for new ways in how to improve the efficiency of existing electric power transformers since the price for new equipment has been increasing significantly in the past twenty years. \u00a0Distribution substations and the transmission network are constantly working at peak or near peak capacity and that leads to much more rapid transformer wear and aging. \u00a0Especially hard hit is the transformer\u2019s liquid and solid insulation.<\/p>\n
If the insulating system is in bad condition, the dielectric properties of insulating oil will be reduced. \u00a0For such a prolem, GlobeCore<\/i><\/b> has developed technology for the regeneration and purification of contaminated oil that restores the oil to its original new like condition. \u00a0Using this advance new technology, oil is circulated through the special regeneration columns filled with Fuller\u2019s Earth sorbent materials. \u00a0Contaminated oil flows to the oil station and is sent back to the transformer in a clean, new like condition.<\/p>\n
Since oil is continuously circulated through the unit, the contaminated oil residues are washed out from the transformer. \u00a0Fuller’s Earth<\/b> (a naturally-occurring sorbent) absorbs impurities and contaminants. \u00a0\u00a0The regeneration time will depend on the amount of oil that needs to be regenerated and the degree of its contamination.<\/p>\n
Gl\u043ebeC\u043ere<\/i><\/b> equipment is desiged to work on energized transformers so there will be no, or minimal service interuptions. \u00a0Another benefit of GlobeCore<\/i><\/b> equipment is that its mobility allows the operators to serve multiple pieces of equipment in remote locations without having to evacuate the transformer to a repair or maintenance facility.<\/p>\n
GlobeCore<\/i><\/b> regeneration technology allows transformer services companies to:<\/p>\n
(1) restore oil to its original like new condition;<\/p>\n
(2) extend the service life of transformers and improve their efficiency;<\/p>\n
(3) carry out \u201cpreventive maintenance\u201d in order to eliminate the need for corrective mainatenance;<\/p>\n
(4) greatly reduce the need to by new oil;<\/p>\n
(5) eliminate the need to dispose of used oil; and<\/p>\n
(6) eliminate the risk of service trouble during power equipment operation;<\/p>\n
GlobeCore <\/i><\/b>technology provides for transformer service life extension, reduction in financial expenditures and improvement of equipment efficiency. \u00a0Contaminated oil residues significanly reduce the service life of windings and operational reliability of transformers. \u00a0Aging of oil-cellulose insulation may lead to irreversible consequences during \u00a0its expected service life.<\/p>\n
GlobeCore<\/i><\/b> technology increases transformer service life thereby reducing operating costs and improving operational reliability.<\/p>\n
Contaminated oil residues reduce significantly the service life of windings and the transformer\u2019s operational reliability. \u00a0Despite the fact that oil-cellulose insulation may be used for more than 25 years, contaminated oil will cause premature failure of the transformer long before the transformer is ready for retirement.<\/p>\n
Factors that have a negative impact on the insulation system of the transformer<\/b><\/p>\n
<\/p>\n
It is better to regenerate oil than to simply change it. \u00a0Products of degradation that have accumulated in the transformer\u2019s solid insulation will get into the new oil within a few months of the oil change. \u00a0As a result, the new oil will lose its performance characteristics much more rapidly than with the GlobeCore <\/i><\/b>rengernation process.<\/p>\n
GlobeCore<\/i><\/b> equipment is considered to be revolutionary since Fuller\u2019s Earth (the active adsorbent filtering system) is able to absorb products of degradation. \u00a0Additionally, oil that is regenerated with GlobeCore<\/i><\/b> equipment is much more resistant to aging. \u00a0When only changing the oil, there is always up to 15% of the contaminated oil left in the transformer that will accelerate the new oil\u2019s aging.<\/p>\n
Due to advanced GlobeCore<\/i><\/b> technology, all contaminated oil residues are washed out of the transformer by the hot oil being circulated through a closed loop that includes the regeneration equipment and the transformer.<\/p>\n
GlobeCore\u2019s<\/i><\/b> regeneration technology is eco-friendly does not generate hazardous waste while regenerating transformer oil and other industrial fluids and oils. \u00a0The Fuller\u2019s Earth, used in the GlobeCore<\/i><\/b> CMM-R line of equipment, absorbs all impurities and is reactivated directly in the equipment precluding the need to stop and dispose of used sorbent during the processing job. \u00a0Each load of Fuller\u2019s Earth will last up to 300 regeneration cycles before needing to be replaced.<\/p>\n

GlobeCor<\/i><\/b>e<\/i> CMM-R line of equipment<\/strong><\/p>\n GlobeCore<\/i><\/b> technology distinguishes itself through the following features:<\/p>\n If your comapny does not perform reglarly scheduled preventive maintenance, unwanted sediments and other contaminants will accumulate in the crital areas of your transformers. \u00a0As a result, the performance characteristics of dielectric insulating oil will be reduced and the likelyhood of a transformer insulation failure will be greatly increased.<\/p>\n The GlobeCore Process<\/i><\/b> of regeneraing dielectric insulating oil is able to dissolve and remove sediments at high temperatures from the transformer\u2019s core and solid insulation. Even previously accumulated sediments may be dissolved and removed from the entire transformer.<\/p>\n The following table shows the limiting values of transformer oil that indicate when it is necessary to regenerate the transformer\u2019s dielectric oil.<\/p>\n Performance Characteristic<\/b><\/p>\n<\/td>\n Value<\/b><\/p>\n<\/td>\n<\/tr>\n Acid number<\/p>\n<\/td>\n >0.08 mgKOH\/g of

cannot be repaired through any modern regeneration technologies on the world market today. \u00a0Regeneration therefore, should be considered as a preventive mantenance procedure as opposed to a corrective maintenance procedure. \u00a0The GlobeCore<\/i><\/b> \u201cService Life Extension Program\u201d<\/i> uses advanced modern technolgy to remove moisture and contaminants that degrade the transformer\u2019s solid insulation. \u00a0It provides for the service life extension of the transformer by removing the progressive aging contaminant from the solid insulation.<\/p>\n
