The TransformerCare Unit TCU is a service unit extending the operating life of oil-filled transformers and reactors.
The continuous degassing, dewatering and filtration of the insulating oil ensure low levels of the oxygen content, water content and particle contamination in the transformer. Plus, it ensures the increase of the breakdown voltage of the insulating oil. Therefore, as a result, the increase of the service life of the insulation also happens. Typically, using the TCU can extend the remaining service life of the transformer by a factor of three.
