Electric Power Transformers are widely used in the energy sector and normally have a long service life provided they are operated properly and receive timely preventive and corrective maintenance.  Recent research however, shows that the failure rate of transformers has been growing annually for several years. The main problems are related to damaged paper insulation surrounding the windings, voltage regulators, and inputs.  Why you may ask?  Well, most, if not all. damage to the insulating paper can be traced back to problems with the dielectric insulating oil.

The insulating paper is the heart of the transformer and oil is the life blood of the transformer.  Once the oil becomes contaminated with acids, moisture and particulate matter, it will transfer these contaminates into the insulating paper.  The paper will then begin to degrade and lose its insulating properties and that will eventually lead to premature transformer failure.  There is a wise old saying. “An ounce of prevention is worth a pound of cure.”  It is therefore, better to maintain your transformers and prevent failures before they happen.

The service life of your transformers life can be extended considerably using the GlobeCore Service Life Extension Program featuring the GlobeCore Process  and our SMM-R Oil Regeneration units manufactured in our factory.  These systems allow you to restore the dielectric strength of insulating oil and restore the transformer insulting oil back to its original new condition.  The GlobeCore Process makes it possible to extend the life of your transformers to between 20-35 years.  Many industry professionals are convinced that there is no reason to buy new transformers if the GlobeCore Process is used to service your aging transformer fleet since the process can save old transformers and extend service life.  If the process is implemented early in the service life of a transformer, an even greater service life extension can be achieved.


A “Unique feature” of the SMM-R regeneration unit is the usage of a sorbent material known as “Fuller’s Earth.”  The Fuller’s Earth sorbent can be regenerated and used over and over again in processing and filtering transformer oil.  The Fuller’s Earth resource will continue to be viable for between 2 and 3 years and it can filter over 90 tons of oil before being safely disposed of without causing environmental harm.  The Fuller’s Earth sorbent is considered environmentally friendly and can be later used as a construction material.  The GlobeCore Process has been able to reach a high level of positive results in processing of transformer oil when using the Fuller’s Earth sorbent materials.  The GlobeCore Process of regeneration using Fuller’s Earth is easy and can be performed by one person directly on the transformer in either energized or de-energized mode.  The process purifies, degases and restores the oil and is capable of removing the contaminates from the core, windings and the insulating paper.  This makes the GlobeCore Process the most advanced and cost effective transformer maintenance system in the world today.


Transformer oil is pumped through the sorbent by means of a pump.  Sorbent is kept in several cylindrical columns through which the oil flows as part of the filtering process.  After the oil passes through the sorbent, the oil is then filtered by means of a second filter for fine filtration.  The oil moves in the vessel for the process of oil collection.  The sorbent material has a micro pore structure allowing for molecular filtration.  During the process of filtration, harmful impurities and products of oil decomposition are left in the granules of the sorbent.  Once the sorbent reaches the point of saturation with impurities, the unit starts the sorbent reactivation process automatically.  During the course of sorbent reactivation, the micropores of the sorbent are cleaned and harmful impurities are removed and placed into a special collector and coal filter.  The Fuller’s Earth Sorbent is capable of completing approximately 300 regeneration cycles before it must be replaced.
