GOST 14965-80 PDF

Full title and description

GOST 14965-80 — "Генераторы трёхфазные синхронные мощностью свыше 100 кВт. Общие технические условия" (English: "Synchronous three-phase generators of power above 100 kW. General specifications"). National standard of the former USSR that establishes general technical requirements, main parameters, test and acceptance rules for three-phase synchronous generators with rated power above 100 kW intended for continuous (S1) operation.

Abstract

This standard defines types, basic parameters, constructional and performance requirements, test methods, installation and mounting dimensions, marking and documentation rules for synchronous three-phase generators with rated power above 100 kW. It sets mandatory technical requirements (electrical, mechanical, thermal and environmental) for machines manufactured for general economic use, and excludes certain classes such as turbogenerators, hydrogenerators and on-board vehicle generators.

General information

• Status: Active / in force (original USSR GOST adopted and retained in national practice; amendments applied).
• Publication date: Approved 1980; effective from 1 July 1981.
• Publisher: State Committee for Standards of the USSR (Gosstandart); text maintained in later national repositories and by successor standards bodies.
• ICS / categories: Electrical rotating machines — generators (commonly classified under ICS 29.160.20 or national group E62).
• Edition / version: Original designation GOST 14965-80 (1980); contains subsequent amendments (noted in the text as amendments 1 and 2 / later editorial updates).
• Number of pages: Approximately 25 pages (standard printing / PDF edition).

Scope

The standard applies to three-phase synchronous generators with rated power above 100 kW designed for continuous nominal operation (S1) as sources of alternating current for general industrial, commercial and utility use. It covers preferred nominal powers, standard nominal speeds and voltages, cooling and connection schemes, mechanical and electrical performance requirements, test conditions and acceptance rules. The standard does not apply to turbogenerators, hydrogenerators or generators intended for on-board use in land, sea or air vehicles.

Key topics and requirements

• Definition of types and preferred nominal powers and voltages for 50 Hz machines (and references for 60 Hz values to product-specific standards).
• Standard nominal rotational speeds (examples: 1500, 1000, 750, 600, 500, 375 rpm) and associated preferred power/voltage groupings.
• Mechanical strength and dynamical requirements (overspeed and short-duration overload capability, resistance to residual deformation).
• Cooling and thermal operating conditions (air-cooling nominal conditions and altitude/temperature derating rules).
• Electrical connection schemes (stator connection star/delta options, winding terminal arrangements and multi-voltage constructions by order).
• Dimensional and mounting requirements — reference to national standards for installation and connection dimensions.
• Test procedures, acceptance rules and inspection requirements (performance, insulation, vibration, noise and routine tests).
• Marking, documentation, packaging and warranty/guarantee provisions appropriate to manufactured generators.
• Mandatory compliance statement: requirements of the standard are obligatory for covered products.

Typical use and users

Primary users are machine manufacturers (generator designers and producers), motor‑generator OEMs, utilities and power system engineers, specifiers for industrial and municipal power plants, procurement and quality assurance teams, test laboratories and certification bodies, and repair/maintenance shops that refurbish or test large synchronous generators.

Related standards

The standard is part of a family of GOST documents for rotating electrical machines and cross-references other national standards for dimensions, test methods and environmental categories (examples: standards covering general machine requirements, test methods for synchronous machines, installation dimensions and climatic categories). It is typically used alongside product-specific GOSTs (or technical conditions) and international standards for rotating electrical machines such as the IEC 60034 series for detailed testing and safety where cross-comparison or export requirements apply.

FAQ

Q: What is this standard?

A: GOST 14965-80 is a national technical standard originally issued by the State Committee for Standards of the USSR that sets general technical specifications for three-phase synchronous generators of rated power above 100 kW.

Q: What does it cover?

A: It covers types and preferred nominal parameters (power, speed, voltage), constructional and performance requirements (electrical, mechanical and thermal), cooling, connection schemes, dimensional and mounting rules, tests and acceptance, marking and documentation for synchronous generators intended for continuous operation.

Q: Who typically uses it?

A: Generator and electrical machine manufacturers, power plant engineers, procurement and QA teams, test laboratories, certification authorities and service/repair organizations use this standard when designing, manufacturing, testing, procuring or certifying large synchronous three-phase generators.

Q: Is it current or superseded?

A: The standard was approved in 1980 and became effective on 1 July 1981. It has recorded amendments and editorial updates; it has been retained in national practice and is treated as a governing specification for the class of machines it covers unless a product-specific technical specification or a later national/regional standard explicitly replaces it for a given application.

Q: Is it part of a series?

A: Yes — GOST 14965-80 is part of the GOST family of standards for rotating electrical machines and is intended to be used together with other GOSTs covering general machine requirements, test methods, dimensions and environmental classifications, as well as with product-specific technical conditions (ТУ) for particular generator models.
