Transformer Overhauling & Maintenance

Transformer overhauling and maintenance is essential to ensure optimal performance, safety, and longevity of electrical equipment. At Powertech, we conduct detailed inspections, cleaning, part replacements, and performance checks to restore transformers to their original efficiency. Our team identifies potential issues early, preventing unexpected failures and costly downtime. We follow strict industry standards and use advanced tools to deliver reliable results. Regular maintenance not only improves operational efficiency but also extends the life of your transformer. Our comprehensive approach ensures your equipment operates smoothly, safely, and efficiently under all working conditions.

Transformer Erection & Commissioning

Transformer erection and commissioning require precision, expertise, and strict adherence to safety standards. Our team handles the complete installation process, including positioning, alignment, assembly, and electrical connections. We ensure all components are properly installed and tested before energizing the transformer. Detailed pre-commissioning checks and performance testing are conducted to guarantee smooth startup and reliable operation. With our systematic approach, we minimize risks and ensure compliance with industry norms. Powertech ensures that your transformer is installed correctly and operates efficiently from day one, delivering dependable performance for long-term use.

Transformer Oil Filtration (Ultra High Vacuum)

Transformer oil plays a critical role in insulation and cooling. Our ultra high vacuum oil filtration process removes moisture, dissolved gases, and impurities that can degrade performance. Using advanced filtration machines, we restore oil quality to required standards, improving dielectric strength and overall transformer efficiency. This process helps prevent insulation failure and enhances operational reliability. Regular oil filtration also extends the lifespan of transformers and reduces maintenance costs. At Powertech, we ensure safe, efficient, and contamination-free oil purification services, helping your equipment perform at its best even under demanding conditions.

Oil Testing & Analysis (BDV, DGA, PPM, etc.)

Oil testing and analysis are crucial for monitoring transformer health and preventing failures. We conduct a range of tests including Breakdown Voltage (BDV), Dissolved Gas Analysis (DGA), and moisture content (PPM) to assess oil condition and insulation strength. These tests help identify internal faults, overheating, and contamination at an early stage. Our advanced testing methods provide accurate and reliable results, enabling timely maintenance decisions. By analyzing transformer oil regularly, we help clients avoid unexpected breakdowns and ensure safe operation. Powertech delivers precise diagnostics for better performance and long-term reliability.

Transformer Testing

Transformer testing is essential to ensure the safety, reliability, and efficient performance of electrical transformers. It involves a series of diagnostic procedures to evaluate insulation strength, detect internal faults, and assess overall operating condition. Common tests include BDV, DGA, insulation resistance, and turns ratio testing, which help identify issues such as moisture, overheating, or winding defects. Regular testing helps prevent unexpected failures, reduces downtime, and extends equipment lifespan. Using advanced tools and expert analysis, transformer testing provides accurate insights, enabling timely maintenance decisions and ensuring uninterrupted power supply across industrial and commercial applications.

Transformer Rewinding

Transformer rewinding is a critical process to restore damaged or aged windings. At Powertech, we offer precision rewinding services for transformers up to 50 MVA capacity. Our skilled technicians use high-quality materials and advanced techniques to ensure proper insulation and performance. The rewinding process improves efficiency, reduces losses, and extends the lifespan of the transformer. We follow strict quality checks at every stage to maintain reliability and safety. Whether due to faults or wear over time, our rewinding services bring your transformer back to optimal working condition with enhanced durability.
