GOST R 52719-2007 PDF

Full title and description

GOST R 52719-2007 — "Power transformers. General specifications" (Russian: ГОСТ Р 52719-2007, Трансформаторы силовые. Общие технические условия). The standard establishes general technical requirements, classification, test and acceptance rules, marking, documentation and safety requirements for general-purpose power transformers and autotransformers.

Abstract

This national standard of the Russian Federation specifies requirements for three‑phase and single‑phase power transformers intended for general economic use, covering ratings, electrical and mechanical characteristics, routine and type tests, marking and documentation. It applies to equipment designed after 1 January 2008 and includes later amendments and corrections.

General information

• Status: Active / in force.
• Publication date: Introduced 01 January 2008 (standard designation year: 2007).
• Publisher: National standard of the Russian Federation — approved and published under the authority of the Federal Agency on Technical Regulating and Metrology (Rosstandart).
• ICS / categories: 29.180 (electrical equipment and power transformers).
• Edition / version: GOST R 52719-2007 (with subsequent amendments and corrections incorporated by later notices).
• Number of pages: Typically published as ~48 pages in commercial distributions (page counts reported 45–48 depending on publisher/format).

Scope

The standard applies to general‑purpose power transformers (including autotransformers and transformers for station auxiliary needs and for packaged transformer substations) — three‑phase units of at least 5 kV·A and single‑phase units of at least 1 kV·A — for voltage classes up to and including 1150 kV. It does not apply to small‑capacity special transformers (converter, furnace, traction, starter, welding, etc.) or transformers with more than three windings, although selected requirements may be used for such equipment where no separate normative documents exist. The standard covers equipment designed from 1 January 2008 onward.

Key topics and requirements

• Classification of power transformers by purpose, cooling and construction types.
• Rated characteristics (power, voltage class, vector group, short‑circuit impedance, losses and efficiency limits).
• Design and materials: insulation systems, tanks, bushings, radiators, and corrosion‑resistant surfaces.
• Thermal performance and temperature‑rise limits; cooling methods and calculation rules.
• Routine, type and acceptance tests (electrical, dielectric, temperature, short‑circuit and noise tests) and required test documentation.
• Tappings and on‑load/off‑load tap‑changer requirements and markings.
• Marking, nameplate data, packing, transport and storage instructions.
• Safety, grounding, maintenance, expected service life and repairability provisions.
• Requirements for technical documentation, quality management references and applicable normative references (including harmonized IEC documents where indicated).

These topics reflect the standard's structure and main clauses covering design, testing, marking and documentation for power transformers.

Typical use and users

Manufacturers of oil‑filled and dry‑type power transformers, electrical design institutes, power utilities, procurement and conformity assessment bodies, testing laboratories, installation and maintenance organizations, and regulatory authorities use this standard when specifying, producing, testing and accepting general‑purpose power transformers in the Russian market or for equipment intended to meet Russian regulatory/contractual requirements.

Related standards

The standard references and aligns with applicable IEC and Russian normative documents for transformers and electrical equipment (for example IEC 60076 series and multiple national GOST/GOST R standards on testing, safety, insulation, materials and quality systems). Amendments and cross‑references to modernized national documents (revised GOST R and GOST series) are included by later corrective notices.
