GOST 982-80 PDF

Full title and description

GOST 982-80 — "Transformer oils. Specifications". The standard sets technical requirements, grades and test methods for mineral transformer (insulating) oils intended for filling electrical equipment such as power transformers and oil-filled switching apparatus.

Abstract

GOST 982-80 is an interstate (former USSR) normative document that establishes classification, accepted properties and production/testing requirements for transformer oils produced from low‑sulphur crude and intended as the primary dielectric/insulating liquid in high-voltage equipment. The standard includes references to test methods (including oxidation stability and dielectric tests), lists applicable oil grades and has been issued with several amendments and corrections.

General information

• Status: In force / acting (document listed as действующий in official collections and databases).
• Publication date: Introduced 01 January 1982 (approved by the USSR State Committee for Standards on 24 Nov 1980; effective 1982-01-01).
• Publisher: Interstate standard (developed by the USSR Ministry of Oil Refining and Petrochemical Industry; approved by the State Committee for Standards of the USSR — Gosstandart).
• ICS / categories: ICS 75.100 (Lubricants, industrial oils and related products).
• Edition / version: Designation year "-80" (ГОСТ 982-80); issued with amendments (indexed in information sources as amended in 1982, 1985, 1988 and later corrections/reissues).
• Number of pages: Typically published as a short specification — commonly shown as 6 pages in standards catalogs (some reprints list 6–7 pages depending on pagination of collections).

Scope

Applies to mineral transformer oils produced by acid and selective refining processes from low-sulphur crude, intended for filling transformers, oil circuit breakers and other high-voltage apparatus as the primary electrical insulating medium. The standard defines allowed product grades (e.g., grades such as T-1500, T-750 and technical-purpose TK), required physico‑chemical and dielectric properties, and references methods for their determination.

Key topics and requirements

• Classification of transformer oil grades and permitted uses for each grade (including special technical grades not intended for transformer filling).
• Essential physical and chemical parameters: oxidation stability, acid number, interfacial tension, water content, density, kinematic viscosity, flash point and presence of low‑molecular acidic volatiles — with specified test methods or references to other GOSTs.
• Dielectric properties and electrical strength testing requirements (breakdown voltage and related dielectric tests).
• Reference to specific test procedures (for example, oxidation stability as described by related GOSTs; the standard cross‑references ГОСТ 981 and other normative documents).
• Packaging, marking and documentation expectations for supplied oils (including product identification by grade and batch test records).

Typical use and users

Used by petroleum refineries and lubricant manufacturers producing transformer oils; quality/control laboratories performing acceptance and periodic testing; electrical utilities and transformer OEMs specifying insulating oil for procurement and maintenance; procurement and certification bodies that verify conformity to GOST requirements. Typical applications are filling power transformers, autotransformers, oil circuit breakers and other oil‑filled high-voltage equipment.

Related standards

GOST 982-80 replaced earlier documents such as GOST 982-68 and GOST 5.1710-72. It cross‑references other test and safety standards for methods (for example, oxidation and dielectric test methods such as those in ГОСТ 981 and safety/hygiene standards). The standard is also noted to correspond in part to the IEC publication 296 for certain oil classes. Amendments and editorial corrections have been published and some reprints appeared in collections of petroleum product specifications.

FAQ

Q: What is this standard?

A: GOST 982-80 is the interstate technical specification that establishes requirements and test references for mineral transformer (insulating) oils used in electrical equipment.

Q: What does it cover?

A: It covers classification of oil grades, required physico‑chemical and dielectric properties, test methods or references to test methods, packaging/marking and related technical provisions for transformer oils.

Q: Who typically uses it?

A: Oil producers, transformer manufacturers, electrical utilities, testing laboratories and procurement/certification authorities use the standard to specify, produce, test and accept transformer oils.

Q: Is it current or superseded?

A: Catalogs and normative databases list GOST 982-80 as действующий (in force) with published amendments and reprints; it replaced earlier GOSTs (for example, GOST 982-68). Users should check national/regional conformity rules or more recent national standards to confirm the applicable technical regulation for procurement or certification.

Q: Is it part of a series?

A: The standard is part of the petroleum products/industrial oils standardization group (ICS 75.100) and references other GOSTs for specific test methods and safety requirements; it has associated amendments and reissues collected in petroleum product technical collections.

Q: What are the key keywords?

A: Transformer oil, insulating oil, dielectric strength, oxidation stability, T-1500, T-750, GOST 982-80.
