PDS provides a variety of solutions for Power Transformer and Dry-type transformer, from time-based maintenance to condition-based monitoring system. With our comprehensive solution, your transformer is safe!

Common root causes of transformer failure:

• Electrical disturbances
• Insulation deterioration
• Lighting surges
• Loose connection
• Overload Moisture
• Line disturbance
• Stress or fatigue
• Poor workmanship
• Others

Useful techniques to prevent transformer failure includes: Dissolved Gas Analysis (DGA), Frequency Response Analysis (FRA), Recovery Voltage Measurement (RVM), Power Factor (PF), Polarization Index, Insulation resistance, moisture analysis and Partial Discharge (PD). Among all the solutions, DGA, power factor and PD are often used for monitoring and have proved their effectiveness in detecting defects related to thermal and electrical issues.
