Generator Step Up Transformer

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.

Generator step up transformer.

Generator step up transformer units are used to increase the voltage of a generator and connect the supply to a bus bar. They must be built to withstand extreme thermal loading without ageing prematurely. 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.

Generator step up transformers gsu one essential component of any power station is a reliable generator step up gsu transformer. They are suitable for nuclear thermal and hydraulic applications from small to high voltages with power ratings from 5 mva to 1000 mva. Generator step up gsu transformers gsu transformers are used worldwide to raise voltages coming from power generation plants including thermal nuclear and hydroelectric. The generator transformer typically consists of a low voltage winding a high voltage winding and an optional high voltage regulating winding to allow some control of the output voltage level.

Generator transformers are also used to limit the fault level of the generator in case of a fault. 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.
