Transformer Test.

As to be expected, we provide you with a complete range of tests on the transformer, for example:

  • Transformer turns ratio
  • Winding resistance
  • Insulation resistance
  • Power factor / dissipation factor / capacitance measurement
  • Magnetization current
  • Short-circuit impedance
  • SFRA (Sweep frequency response analysis)
  • TAPSCAN® VAM (on-line tap-changer diagnostics using vibro-acoustic measurements)
  • TAPSCAN® DRM (on-line tap-changer diagnostics using dynamic resistance measurements)

Using visual inspections and historical data, our experts can recommend measures that ensure the availability of your transformers for the long-term. We would also be happy to implement these suggestions for you.
