Generator step-up transformers up to 765 kV
Generator step-up transformers for voltages up to 765 kV. They raise the generator voltage of power plants to the transmission network level. They are built as three-phase units and as groups of single-phase transformers.
- Example designs
- 700 MVA 275/20 kV; 590 MVA 420/18.5 kV; group of 3 single-phase units of 360 MVA each at 512.5/20.5/20.5 kV
- Generator voltage
- usually 15–24 kV
- Design
- independent clamping of windings and core
- Production
- Nijmegen, Netherlands
