🛠️ Annual Maintenance Contract (AMC)

Nakoda Products offers comprehensive Preventive AMC services to ensure the safe, reliable, and long-lasting performance of your transformers. While transformers are static devices with low maintenance needs, they are not maintenance-free. Our AMC program helps detect issues early, preventing costly failures and extending equipment life.

🔍 Why Preventive AMC Matters

Regular maintenance enables:

    • Early detection of faults
    • Prevention of insulation breakdown and oil degradation
    • Improved operational safety and efficiency
    • Optimized transformer lifespan
🧪 Preventive AMC Includes

✅ Diagnostic Testing

  • Oil Sampling & Analysis
    • Oil quality
    • Moisture content
    • Furan detection
    • PCB contamination
  • Electrical Measurements
    • Insulation resistance
    • Winding resistance
    • Transformer Turn Ratio (TTR)
    • SFRA (Sweep Frequency Response Analysis)
  • Accessory & Protection Checks
  • Buchholz relay
  • Gas pressure and temperature sensors
  • Thermometers and cooling fans
  • Silica gel replacement (if required)
    🧠 Condition-Based Maintenance Planning
