In our test laboratories, all tests demanded under IEC and TSE standards excluding mechanical resistance test against short-circuits can be conducted for our oily distribution transformers, dry type distribution transformers and power transformers.
Our systems:
1. Test area of transformers having 150 MVA power and of which the highest operation voltage is 220 kV.
2. Test area of transformers having 30 MVA power and of which the highest operation voltage is 36 kV.
Transformer Routing Tests:
They are the tests conducted for every transformer produced.
Measurement of voltage cycle rate and control of voltage vector phase shift (TTR test)
Measurement of coil resistance
Test of AC resistance voltage with separate source (Test of applied voltage)
Test of Induced AC voltage (Induced voltage test)
Measurement of idle loss and current
