Transformer Overhauling, Testing & Commissioning
Heat, oil, insulation — every weakness shows up in tests before it shows up in failures.
Peak performance
Fault-free flow
Extended life
A weak transformer is a ticking time bomb in disguise
At KKEC, we overhaul, test, and commission power transformers to factory standards. From winding checks to oil analysis, we validate every system so your transformer runs strong from day one and stays that way.
It pays to overhaul and test
Assured reliability
Thorough testing catches faults before they become crises.
Reduced unplanned outages
Smarter commissioning prevents sudden failures.
Cost-effective longevity
Overhaul beats replacement and extends transformer life.
Insight-driven safety
Oil, insulation, winding checks ensure leak- and fault-free operation.
Every stage, tested and verified
Visual & Mechanical Inspection
Ensure installation and transport integrity.
Winding Resistance & Ratio Tests
Confirm correct turns ratio and detect winding faults.
Insulation, Tan-δ & Hi-Pot Tests
Validate dielectric health and prevent failure.
Oil Analysis & PD Monitoring
Sample oil, test breakdown voltage, and detect partial discharges.
Functional Energization & Load Testing
Energize and verify under real load before handover.
Load Tap Changer (OLTC) Tests
Verify tap changer operation, contact timing, and switching performance.
Core & Winding Temperature Tests
Measure heat under simulated loads to confirm cooling efficiency and thermal stability.
DGA/PD Monitoring
Test oil breakdown voltage, analyze dissolved gases, and detect partial discharges for predictive insights.
Top-grade tools. Top standards.
Megger & Hi-pot testers
