23、 Applications. Large hydraulic turbine-driven generators are shipped as components and completely assembled and installed at the site. The installation, therefore, becomes a continuation of the manufacturing process, and many of the operations involved are those that are normally performed in the fa
24、ctory on smaller generators. Close tolerances must be maintained in the fit and alignment of the various parts. The use of proper installation procedures is essential to achieve satisfactory operation of the unit. This guide, originally intended for new construction, continued to be useful whenever
25、the generator rotor or turbine is reinstalled in its operating placement, following removal for maintenance or repair. This guide incorporates much of the information previously found in the National Electrical Manufacturers Association (NEMA) publication MG 5.2, Installation of Vertical Hydraulic-T
26、urbine-Driven Generators and Reversible Generator/Motors for Pumped Storage Installations. MG 5.2 was originally issued in 1972 and revised in 1975 and 1977. NEMA sponsorship was withdrawn and MG 5.2 was rescinded in September, 1982. The Hydroelectric Power Subcommittee felt that this guide continue
27、d to provide usefulness to the hydropower industry and in 1985 decided to undertake the maintenance of this guide for the benefit of the body of users. In 2006, the Hydroelectric Power Subcommittee decided to review this guide to address significant technology changes impacting the installation of v
28、ertical generators and generator motors for hydroelectric applications that have occurred since this guide was originally prepared. Guidelines contained in this document were harmonized with current international practices. Copyright 2012 IEEE. All rights reserved. ixContents 1. Overview 1 1.1 Scope

Considerable time and money can be lost if these items are not ready when needed. The responsibility for the supply of erection tools and materials falls into the following main categories: a) Those supplied by the erector b) Those supplied by the manufacturer c) Those supplied by the customer The following subclauses will briefly describe these categories and will act as a guide for a t
