Transformer Testing

Transformer Oil Testing


We provide excellent transformer oil testing services through our experienced professionals. We test the transformers on various crucial parameters such as:

  • Specific Resistance (Resistivity)
  • Dielectric Dissipation Factor (Tan Delta)
  • Neutralization Value (Acidity)
  • Sediment (Sludge)
  • Flash Point
  • Water Contents (PPM)
  • Inter facial Tension
  • Dielectric Strength (BDV)
  • Dissolved Gas Analysis
  • Appearance
  • Density
  • Kinematic Viscosity
  • PNA Analysis (Paraffinic, Naphthanic & Aromatic content)
  • Pour Point
  • Corrosive Sulphur
  • Oxidation Stability
  • Aging Characteristic
  • Presence of oxidation Inhibitor
  • SK Value

Transformer Life Assessment


Our testing process for transformer life assessment is in strict accordance with various international norms and standards and is done with sophisticated machines. The tests for transformer life assessment are performed on the parameters such as:

  • Furan Analysis
  • Degree Of Polymerization on Paper (DP)
  • PCB Analysis
  • Metal Content
  • Inhibitor Content
  • Metal Sulphate
