Siemens Limited starts dispatching GSU transformers to NTPC

摘要

Siemens Limited has begun dispatching its largest-ever 'Made in India' single-phase Generator Step-Up (GSU) Transformer of rating 315 MVA, 23.5 kV / 420 kV for installation at National Thermal Power Corporation's (NTPC) Kudgi Super Thermal Power Station in Bijapur district of Karnataka. Normally, generated voltage is in the range of 11 kV to 24 kV, which is not efficient to transmit power through transmission lines. Generator Step-Up (GSU) transformer is a special purpose transformer, which is used to step up generator voltage to high voltage (400 to 765 kV), for efficient transmission of generated power to load centres located at long distances. GSU transformers are essential components of the power station, which once operational, will boost high-capacity power generation for the South Indian states of Karnataka, Andhra Pradesh, Tamil Nadu and Kerala. NTPC has ordered 10 units of these GSU transformers from Siemens.
