About this document
Chapter-6 Generator Transformer and Insulation Coordination by yao is a document available to read on EtoBox.
The document discusses generator transformers used in hydroelectric power stations. Generator transformers step up the voltage from generators (0.415-11kV) to transmission system voltages (12-420kV). They are typically three-phase, oil-immersed transformers located outdoors. Cooling systems include ONAN, ONAF, OFAF and ODWF. Temperature rise, overload capacity and continuous ratings are specified conservatively. Transformer standards and electrical characteristics like type, ratings, overloads and testing a
