Oil Analysis and Diagnostics

On-Site Transformer Services

We offer comprehensive transformer oil analysis services in accordance with IEC standards to evaluate oil condition and detect early signs of internal faults. 

Available analyses include:

• Breakdown voltage measurement (IEC 60156)
• Water content analysis (IEC 60814)/li>
• Acidity / neutralization number (IEC 62021-1)
• Interfacial tension (IEC 62961)
• Dielectric dissipation factor (tan delta) at 90°C (IEC 60247)
• Dissolved Gas Analysis (DGA) for power transformers (IEC 60567 / IEC 60599)
• Inhibitor content measurement (IEC 60666)
• PCB testing
.

Based on test results, we provide clear recommendations for maintenance or corrective actions.
