This document specifies general technical requirements, as well as product marking, material and components storage, factory and site tests, supply requirements, etc. for hydrogenerators and their auxiliary equipment.
This document is applicable to three-phase salient-pole synchronous generators (Hereinafter referred to as hydrogenerators) directly linked to hydraulic turbine with rated frequency of 50 Hz or 60 Hz, rated output of 25 MVA and above. For hydrogenerators with the rated output below 25 MVA, this document can be referred to for implementation.
NOTE For special clauses of pumped storage motor-generators, see GB/T 20834.
