High Power Transformer GSU System intertie transformers
Generator step-up transformers (GSU) are the critical link between the power station and the transmission network, often operated day and night at full load. They must be built to withstand extreme thermal loading without ageing prematurely. ABB have successfully passed the world's first and highest voltage short circuit test, on a 315 mega volt ampere (MVA), 765 kilovolt (kV) generator step up transformer (GSU).
GSU take the voltage from the generator voltage level up to the suitable transmission voltage level.
These transformers are located in a power station and are built as single-phase or three-phase units.
