| Power Factor | ASTM D 924 |
| Water content | ASTM D 1533 |
| (IFT) Interfacial Tension | ASTM D 971 |
| Acidity or Neutralization Number(NN) | ASTM D 974 |
| Color | ASTM D 1500 |
| Disolved gas analysis (DGA) | ASTM D 3612 |
| Furan Analysis | ASTM D 5837 – HPLC |
| Inhibitor Content | ASTM D 2668. |
| PCB | EPA |
Based on our experience and with the results of previous tests, a specialized technical report is delivered to the customer giving them the recommendations and the real condition of the transformer and the maintenance activities that are required.
Monitoring and maintaining the quality of the insulating oil are essential steps to ensure optimal operation of electrical equipment and maintain the reliability of electricity supply.
A high level of deterioration of insulating oil causes a decrease in life expectancy and therefore a reduction in the margin of safety equipment operation.
