Transformer Oil Testing

Routine testing of transformer oils and insulating oils on a regular schedule is an accepted industry practice. General and physical tests are suggested twice a year, dissolved gas analysis once a year, and Furan testing every 2 years for transformers in operation at least 5 years.

AES Laboratories provides complete transformer oil and insulating oil analysis and testing services.  The following tests are generally carried out for ensuring the good health of transformer oil or other insulating liquids.

  • Appearance
  • Dielectric Breakdown Voltage
  • Density at 15°C
  • Specific Gravity
  • Water Content
  • Sediment, Sludge
  • Interfacial Tension
  • Kinematic Viscosity
  • Neutralisation Value mg KOH/g
  • Disipation Factor at 100°C
  • Flash Point
  • Dissolved Gas Analysis
  • Furans Analyss
  • Particle Count (NAS 1638,ISO 4406)
