Generator Step Up Transformer

This gsu is the link between the transmission network and the power station.

Generator step up transformer.

They must be built to withstand extreme thermal loading without ageing prematurely. Many of the challenges with the design of generator step up transformers relate to the extremely high currents in the lv windings and the magnetic fields produced by the heavy current connections. Generator transformers are also used to limit the fault level of the generator in case of a fault. Generator step up gsu transformers gsu transformers are used worldwide to raise voltages coming from power generation plants including thermal nuclear and hydroelectric.

They are suitable for nuclear thermal and hydraulic applications from small to high voltages with power ratings from 5 mva to 1000 mva. Transformers used for these applications are called generator step up units. Being faced with constantly changing voltage the gsu transformer must maintain the ability to withstand overloads. 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.

Ge s generator step up gsu transformers are designed and manufactured to stringent standards providing superior performance and long life. Typical configurations require a delta connected lv winding to induced currents in the generator and wye connected hv windings to connect to the transmission lines.
