Advanced Generator Repair, Overhauling & Condition Monitoring Solutions
At GTA ENGINEERING LIMITED, we provide specialized services for turbo generators up to 220MW, 11kV, driven by thermal, hydro, and gas turbines. We support power plants and industrial facilities with reliable, high-quality engineering solutions.
Our expertise covers complete lifecycle support, from fault diagnosis to full-scale rehabilitation and performance optimization.
We restore generator components to optimal condition using advanced engineering techniques, including:
- Stator and rotor rewinding.
- Insulation repair and upgrading.
- Core damage repair and re-stacking.
- Shaft and journal refurbishments.
- Slip ring and brush gear repair.
We offer comprehensive overhaul services to extend equipment lifespan, such as:
- Complete dismantling and inspection.
- Replacement of worn or damaged parts.
- Bearing inspection and replacement.
- Cooling system overhauls (air, hydrogen, and water-cooled systems).
- Alignment and reassembly.
We provide real-time monitoring and predictive maintenance solutions, including:
- Online and offline testing.
- Insulation resistance and polarization index testing.
- Vibration and temperature monitoring.
- Winding resistance, high voltage testing (Hi-Pot), and Tan Delta tests.
- Root Cause Failure Analysis (RCFA).
- Final commissioning and operational support.
We are dedicated to delivering reliable, efficient, and cost-effective generator solutions that enhance performance, extend service life, and ensure uninterrupted power generation.
