Home Our Projects Assembly, oil treatment, and commissioning of 6 autotransformers 200 MVA 225/90/11 kV
On-Site Assembly of Autotransformers
Complete Commissioning of the Autotransformers:
- Installation and connection of the autotransformers.
- Analysis, filling, and treatment of autotransformer oil.
Execution of Electrical Tests on the Autotransformers :
- Measurement of the transformation ratio (Ratio Test).
- Measurement of winding resistance.
- Measurement of insulation resistance and polarization index.
- Dielectric tests and power factor measurement (Tan Delta).
Execution of Specific Electrical Tests on the Autotransformers:
- Measurement of no-load and reduced-voltage excitation currents.
- Short-circuit impedance measurement.
- Load transfer tests between windings.
- Verification of tap changers and their continuity.
