Transformer Refurbishment, Maintenance, and Repowering
TSEA provides refurbishment, maintenance, and repowering services for transformers and associated electrical equipment across transmission, distribution, generation, and industrial applications.
Refurbishment
Refurbishment scope is defined based on condition assessment and technical diagnostics.
Activities may include:
- Replacement of windings (partial or complete)
- Evaluation and reuse of the core and tank, when technically appropriate
- Repair or replacement of bushings, sealing systems, and auxiliary components
- Modernization of monitoring and control systems
- Engineering adaptations for older or out-of-production units
Interventions are established according to applicable technical standards and asset-specific requirements.
Maintenance
Maintenance services include preventive, predictive, and corrective activities for transformers, voltage regulators, reactors, and related equipment.
Scope may include:
- Leak correction and gasket replacement
- Bushing replacement or adaptation
- Rubber bladder replacement
- Insulating oil treatment and regeneration
- Active part drying with URSI measurement
- Electrical testing and condition monitoring
Maintenance planning is based on technical evaluation and diagnostic findings.
Repowering
Repowering services address transformer capacity adjustments to meet updated load or system requirements.
Engineering evaluation determines feasibility, required modifications, and compliance with applicable standards.
Scope may include:
- Winding redesign and electrical recalculation
- Core reuse evaluation
- Cooling system review and modification (radiators, fans, heat exchangers)
- Control cabinet update
- Thermal and insulation system reassessment
Engineering studies determine feasibility, required modifications, and compliance with applicable standards.
