International power seminar: Transformer testing


A seminar offering participants theoretical and practical knowledge for testing transformers. The seminar will be conducted in English.


Basics of Power Transformer design, bushings, tap changer

Routine test procedures

  • Winding resistance
  • Ratio, vector group
  • Insulation resistance test
  • tanDelta test
  • Oil breakdown and tanDelta test

Advanced test methods:

  • Dielectric Frequency Response - DFR
  • Sweep Frequency Response Analysis - SFRA
  • Dynamic Resistance Measurement - DRM

Multifunction instruments vs. test van solutions:

  • TRAX, TTV: operation
  • Reporting with PowerDB

Practical measurements in small groups


General technical knowledge of electrical power systems. Knowledge of power transformers is an advantage.
