Scope

This standard specifies the technical requirements, scope of supply, testing and acceptance, marking, packaging, transportation and storage, installation, trial operation and warranty period, spare parts, special tools, and basic requirements for technical documentation of small-scale hydroelectric generators.
This standard applies to vertical or horizontal (except for bulb-through-flow type) salient-pole synchronous generators with three phases, 50 Hz, 125 kVA and above, and below 12,500 kVA (hereinafter referred to as hydroelectric generators). Hydroelectric generators with a frequency of 60 Hz can also be implemented in accordance with this standard.
