Transformers

The PRANA system is used for online monitoring and prediction of the technical condition of transformers. Main types of defect:

  • disturbance of thermal conditions;
  • moisture content in oil and solid insulation;
  • oil gas content;
  • voltage surges;
  • partial discharges in insulation;
  • disturbance of vibration parameters and load modes.

Distribution of faults through transformer components (cumulative statistics):

  • transformer tap changer: 40%;
  • winding: 30%;
  • bushing/leads: 14%;
  • oil tank: 6%;
  • core: 5%;
  • cooling system: 5%.
