Assembly and Commissioning
Assembly and conditioning for the commissioning of our entire range of products at voltage levels up to 500 kV and power rating of 250 MVA. Each stage of the assembly process of a transformer is carried out by highly qualified professionals, applying a work plan that has been previously agreed upon with the client.
On-Site Measurements
Carrying out electrical measurements as part of a maintenance and inspection plan for transformers is essential to help locate the causes of defective operations that are not observed with a simple analysis. The data gathered through electrical measurement instruments are interpreted and analyzed by our qualified personnel, who provide an accurate diagnosis.
The main electrical measurements for the maintenance of transformers that can be carried out on-site are:
- Insulation resistance measurement (with polarization index and absorption index determination)
- Ohmic resistance measurement of windings
- Transformer turns ratio test (TTR), polarization, and vector group determination
- Transformer tan delta test
- HV bushings tan delta test
- Sweep frequency response analysis
- Checking and calibration of protections and auxiliary circuits
- Turn ratio test for current transformers (internal measurement transformers)
- Dew point measurement to determine the humidity level in the transformer’s insulation
