CMM-12R OIL REGENERATION SYSTEMS
The GlobeCore regeneration[mfn]Oil regeneration – is extraction of contaminants from oil in order to restore its original properties to be used equally with fresh oils.[/mfn] process restores used oils to new like condition. This process makes it possible to fill transformers[mfn]The term “transformer oil filling” has two meanings. The first is the process that compensates for the loss of oil in the course of transformer operation. The second is filling a transformer with oil before commissioning or after an overhaul.[/mfn] with oil that would previously have required disposal. The oil in the transformer[mfn]A transformer is a static electrical device that transfers electrical energy between two or more circuits.[/mfn] can be used without replacement for the entire service life of the transformer.
The GlobeCore CMM-R systems are designed to extend transformer service life by restoring the dielectric strength[mfn]The term dielectric strength has the following meanings: 1) Of a pure insulating material, the maximum electric field that the material can withstand under ideal conditions without breaking down (i.e. without failure of its insulating properties). 2) For a specific configuration of dielectric material and electrodes, the minimum applied electric field (i.e. the applied voltage divided by electrode separation distance) that results in breakdown. This is the concept of breakdown voltage.[/mfn] and chemical composition of dielectric insulating oil[mfn]Insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties.[/mfn].
In the process of oil regeneration, oil degradation products and acidic compounds are removed, the oil becomes clear, oxidation resistance is improved, while gas solubility is reduced.
