Importance of oil in electrical performance
Insulating oil plays an essential role in the electrical and thermal performance of transformers. Degradation of its properties can compromise equipment safety and efficiency. TSEA’s insulating oil treatment ensures the fluid maintains proper operating conditions, contributing to electrical stability and extended transformer service life.
Removal of contaminants and moisture
Through advanced technical processes, insulating oil treatment removes solid particles, moisture, and dissolved gases that negatively impact dielectric performance. TSEA performs the service using high-performance equipment, ensuring oil recovery and improvement of its physicochemical characteristics. In addition, TSEA’s Services Unit provides oil analysis with the issuance of a technical report, ensuring traceability and reliability of results.
Why TSEA?
- Restoration of dielectric properties
- Failure prevention
- Execution in field or workshop
Failure prevention
Periodic execution of insulating oil treatment is an effective preventive measure to reduce the risk of electrical failures and premature aging. By restoring oil properties, TSEA helps minimize outages, extend transformer service life, and maintain continuous operational reliability.
Performance and Safety Recovery
Revitalization services apply to transformers from different manufacturers and are not limited to TSEAmanufactured equipment.
TSEA’s transformer revitalization process begins with a detailed assessment conducted by a specialized team to identify failures, wear, and critical points of the equipment. Based on this diagnosis, actions are defined such as cleaning and washing of the active part, elimination of leaks, replacement of gaskets, review of wiring and cabling, control and accessory inspection, as well as insulating oil treatment. These interventions restore safe operating conditions and significantly improve transformer performance.
Transformer Revitalization
Transformer revitalization is an effective technical solution to recover the performance, reliability, and safety of aged equipment, reducing operational risks and postponing the need for asset replacement. TSEA offers specialized revitalization services based on proven processes and targeted technical interventions that ensure greater efficiency and extended durability for transformers.
This service is designed for asset operators and utilities seeking to modernize their equipment and ensure operational continuity with high technical standards. All studies and engineering designs are carried out by TSEA’s internal engineering team, with customized solutions tailored to each client’s operational needs.
Revitalization is recommended for situations in which a full structural refurbishment or power increase is not required, focusing instead on functional recovery, operational reliability, and modernization of selected components.
TSEA Technical Expertise
TSEA’s transformer revitalization stands out for the technical expertise applied at every stage of the service. Activities can be carried out either in the field or at the factory, depending on project requirements. With customized solutions and a focus on safety and efficiency, TSEA delivers revitalized transformers that meet the operational and technical demands of the electrical system.
