Scope

This standard specifies the technical requirements, scope of supply, testing, acceptance, marking, packaging, transportation and storage, installation, trial operation and warranty period, spare parts, special tools, and basic requirements for technical documents of small hydroelectric generator products. This standard applies to 3-phase, 50Hz, 125kVA and above, 12500kVA below vertical or horizontal (except bulb tubular) salient pole synchronous generators (hereinafter referred to as hydro generators). A hydroelectric generator with a frequency of 60Hz can also be implemented as a reference.
