In the test room, the transformers are subject to a series of measurements and tests. Routine tests are carried out on all transfomers prior shipping.

Once the routine tests are complete, the protection instruments and other accessories are fitted on the transformer and then the transformer is subjected to a complete final check. Subsequently the rating plate is fixed on the tank.

Routine Tests:
  • Voltage ratio and phase displacement IEC 60076-1
  • Insulation resistance IEC 60076-1
  • Applied Voltage test IEC 60076-3
  • Induced voltage test IEC 60076-3
  • No load loss test IEC 60076-1
  • Winding resistance  IEC  60076-1
  • Impedance and load loss test IEC 60076-1
  • Control wiring, auxiliary operation
Upon request, witnesse type/special tests can be carried out.

Collaboration with leading laboratories guarantees independent validation and high reliability of our transformer designs.

We send transformer samples for testing to internationally accredited laboratories such as SVEPPI in Siemens for testing short-circuit strenght.

All our measuring instruments are regularly transported for calibration to internationally accredited institutions.

This includes leading European calibration centres such as the Nikola Tesla Institute in Belgrade, ensuring full compliance with IEC standards, traceability, and internationally recognized measurement accuracy.
