The TransformerCare Unit TCU is a service unit designed to extend the operating life of oil-filled transformers and reactors.
The continuous degassing, dewatering and filtration of the insulating oil ensures that the oxygen content, water content and particle contamination in the transformer is kept low and the breakdown voltage of the insulating oil is increased. As a result, the service life of the insulation is also increased. Typically the remaining service life of the transformer can be extended by a factor of three.
The throughput of approx. 15 m³/week prevents the formation of damaging turbulence in the transformer. The TCU is used throughout the life of the transformer, while the transformer is connected and in operation.
The volume of fault gases removed using the TCU corresponds to the gas formation rate in the transformer, which can be interpreted in accordance with DIN EN 60599* or DGA (Dissolved Gas Analysis). In addition, humidity and total gas content in the insulating oil can be monitored online, and an alarm can be triggered in good time in the event of significant changes.
- Preserves the insulating property of the transformer oil
- Increased operating reliability
- Fault gas analysis is possible, similar to DGA
- Extends the remaining service life of the transformer by slowing down the process of cellulose ageing
