Guidance for installation procedures and tolerances of hydroelectric machines - Part 1: General aspects (IEC 63132-1:2020)

The purpose of this part of IEC 63132 is to establish, in a general way, suitable procedures and
tolerances for the installation of hydroelectric turbines and generators. This document presents
a typical assembly. There are many possible ways to assemble a unit. The size of the machines,
design of the machines, layout of the powerhouse and delivery schedule of the components are
some of the elements that could result in additional steps, the elimination of some steps and/or
assembly sequences.
It is understood that a publication of this type will be binding only if, and to the extent that, both
contracting parties have agreed upon it.
Installations for refurbishment projects or for small hydro projects are not in the scope of this
document. An agreement between all parties is necessary.
This document excludes matters of purely commercial interest, except those inextricably bound
up with the conduct of installation.
The tolerances in this document have been established upon best practices and experience,
although it is recognized that other standards specify different tolerances.
Wherever this document specifies that documents, drawings or information is supplied by a
manufacturer (or manufacturers), each individual manufacturer will furnish the appropriate
information for their own supply only.

Lignes directrices des procédures et tolérances d'installation des machines hydroélectriques - Partie 1: Aspects généraux (IEC 63132-1:2020)

IEC 63132-1:2020 L’objectif de la présente partie de l'IEC 63132 est d’établir, d’une façon générale, des procédures et des tolérances adéquates pour l’installation des turbines et alternateurs hydroélectriques. Ce document présente un assemblage typique. Il y a plusieurs façons possibles pour assembler un groupe. Les dimensions des machines, la conception des machines, le plan de la centrale et l’échéancier des livraisons des différentes composantes sont quelques éléments qui peuvent résulter en l’ajout d’étapes, l’élimination des certaines étapes et/ou des séquences d’assemblages.
Il est entendu que ce type de document sera contraignant seulement si, et dans la mesure où, les deux parties contractuelles l’ont convenu.
Les installations pour les projets de réfections et pour les projets hydroélectriques compact ne font pas partie du domaine d’application de ce document. Un accord entre les différents parties est nécessaire.
Ce document exclut les questions d’intérêt purement commercial, sauf celles inextricablement liées au déroulement de l’installation.
Les tolérances mentionnées dans ce document ont été déterminées selon les meilleures pratiques et l’expérience, bien qu’il soit reconnu que d’autres normes spécifient des tolérances différentes.
Partout où ce document précise que des documents, des dessins ou des renseignements sont fournis par un fabricant (ou par des fabricants), chaque fabricant fournira les informations appropriées pour leur propre approvisionnement seulement.

GUIDANCE FOR INSTALLATION PROCEDURES
AND TOLERANCES OF HYDROELECTRIC MACHINES –

Part 1: General aspects

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
o
