PDC Analysis on Power Transformers
The PDC analysis is going to tell you:
Practical Experience, see these technical papers:
- The condition of insulating oil. The results include “Oil Conductivity” in pS/m.
- The condition of insulating paper. The results include “Moisture in Pressboard” in % by weight.
- The cause of insulation trouble. PDC identifies whether the insulation system has the trouble due to "Polarisation" (such as oxidation-by-products) or "Conduction" (mostly caused by water).
- The efficiency of Oil Reclamation or Refurbishment process.
- Result of various dielectric properties: Insulation Resistance and Polarisation Index, Frequency scan of Capacitance and Dielectric Dissipation Factor (DDF), Recovery Voltage Polarisation Spectrum.
