Applied Tests
The following routine and type tests as prescribed by TS 267 are applied to transformers whose assembly has been completed and oil filling has been completed after drying.
Routine Tests
- Measuring winding resistances
- Checking polarity or connection group
- Measurement of short circuit voltage and load losses
- Measurement of no-load losses and current
- Induced voltage test
- Applied voltage test
- Measuring insulation resistances
- Measurement of DC insulation resistance
Special Tests
- Checking the breakdown voltage of oil
- Measurement of the loss angle (tg) (DÜBLE test)
- Measuring Paint Thickness
Type Tests
- Temperature increase (Heating experiment)
- Temperature increase (heating test)
- Full wave impulse test Measurement of audible noise level
- Boiler Omar test) (For Hermetic Transformers)
- Mechanical endurance test against short circuits
(This experiment is carried out abroad in CESI/ITALY, IPH/GERMANY test laboratories.)
Except for the mechanical strength test against short circuits, all other types of tests are carried out in our company laboratory.
