Transformer oil testing 

     1. Dissolved gas analysis

     2. Furan analysis

     3. PCB analysis

     4.General electrical & physical tests:

      a.  Color & Appearance

      b. Breakdown Voltage

      c. Water Content

      d. Acidity (Neutralization Value)

      e. Dielectric Dissipation Factor

      f. Resistivity

      g. Sediments & Sludge

      h. Flash Point

      i. Pour Point

      j. Density

      k. Kinematic Viscosity

    

• General and physical tests - 6 month 
• Dissolved gas analysis - yearly
• Furan testing - once every 2 years
