Insulating Oil Treatment and Transformer Revitalization
Insulating oil treatment is performed to remove moisture, dissolved gases, and contaminants that may affect dielectric properties and transformer operation.
Services are executed in the field or at TSEA facilities, depending on asset condition and project requirements.
Scope includes oil filtration, dehydration, degassing, and technical evaluation of oil condition in accordance with applicable standards.
Engineering support is available to define treatment procedures aligned with transformer design characteristics and operating conditions.
Oil Condition and Treatment Scope
Insulating oil influences the dielectric and thermal behavior of transformers. Variations in moisture content, dissolved gases, and particulate contamination may affect operating parameters.
Oil treatment includes filtration, dehydration, and degassing processes aimed at restoring oil characteristics within applicable technical limits.
Services may include laboratory analysis and issuance of technical reports to document oil condition and treatment results, in accordance with relevant standards.
Transformer Revitalization Scope
Transformer revitalization includes targeted technical interventions intended to restore operational condition and address degradation identified during inspection.
Services may apply to transformers from different manufacturers and are defined based on technical assessment and diagnostic findings.
Scope may include:
- Cleaning and washing of the active part
- Leak correction and gasket replacement
- Inspection of wiring, cabling, and accessories
- Control cabinet review
- Insulating oil treatment
Revitalization is typically applied when full structural refurbishment or capacity uprating is not required, focusing instead on functional recovery and modernization of selected components.
Activities may be executed in the field or at TSEA facilities, depending on project requirements.
