Remanufacturing
Mahati Industries offers comprehensive remanufacturing solutions for power transformers up to 500 MVA, ensuring extended service life, enhanced efficiency, and reliable grid performance. Our expertise in diagnostics and design leads to optimised performance allowing utilities and industry operators to improve reliability for their transformers and electrical infrastructure.
Our Capabilities
-
At Mahati, we conduct in-depth root cause analysis (RCA) to identify failure points in power transformers, whether due to electrical, thermal, mechanical, or environmental factors. Based on these insights, we implement advanced redesign solutions, enhancing insulation, cooling, and structural integrity to improve reliability, efficiency, and lifespan. Our approach ensures optimal performance, minimises downtime, and meets the highest industry standards.
-
Full-scale diagnostic and redesign that covers insulation, restoration and rewinding.
-
Flexible service solutions based on criticality and downtime constraints.
-
Advanced coil rewinding and insulation system upgrades to enhance dielectric strength and heat resistance.
-
Ensuring precise voltage regulation and improved load handling for existing transformer fleets.
-
Improvements in efficiency, energy loss mitigation, and cooling system upgrades.
-
Mahati utilises advanced Vapour Phase Drying (VPD) technology to ensure thorough and uniform insulation drying in remanufactured transformers. This process effectively removes moisture, reducing dielectric stress and enhancing the reliability, efficiency, and lifespan of the transformer.
-
Extensive factory and field testing including dielectric tests, partial discharge analysis, and thermal performance evaluation.
Why Remanufacture?
Over time, transformers experience insulation degradation, mechanical stress, and thermal wear, impacting reliability and efficiency. Replacing a transformer can be costly and time-consuming while remanufacturing restores performance at a fraction of the cost. Mahati’s precision-driven approach ensures that transformers return to service with upgraded insulation, optimised electrical parameters, and improved thermal management, extending operational life significantly.
-
Extending the life of critical transmission and distribution assets.
