Scope
This document specifies the general technical requirements for power generation motors and their ancillary equipment, as well as requirements for product identification, material and component storage, factory and on-site testing, supply, trial operation, and warranty periods, etc.
This document applies to three-phase, 50 Hz, reversible salient-pole synchronous power generation motors (hereinafter referred to as "power generation motors") directly connected to water pumps and turbines with a rated capacity of 100 MVA or more. Units with a rated capacity of less than 100 MVA or units operating at a frequency of 60 Hz shall refer to this document for implementation.
