GOST 1516.3-96 PDF

Full title and description

GOST 1516.3-96 — Electrical equipment for a.c. voltages from 1 to 750 kV. Requirements for dielectric strength of insulation. (Russian: Электрооборудование переменного тока на напряжения от 1 до 750 кВ. Требования к электрической прочности изоляции).

Abstract

This interstate (GOST) standard specifies requirements and test voltages used to verify the dielectric strength of insulation for a wide range of a.c. electrical equipment rated from 1 kV up to 750 kV. It sets criteria for power-frequency and impulse tests, coordination of insulation classes and references international practice (conforms to IEC 71-1:1993 in the relevant parts).

General information

• Status: Interstate GOST; listed as acting/current in national catalogs.
• Publication date: Designation year 1996 (GOST 1516.3-96); introduced as Russian state standard from 1 January 1999.
• Publisher: Interstate Council for Standardization, Metrology and Certification (EASC) / Gosstandart (published under the Interstandard/GOST system).
• ICS / categories: ICS 29.035.01 (Electrical engineering — Insulating materials and insulation coordination).
• Edition / version: Original interstate edition 1996 (adopted and put into effect as national from 1999).
• Number of pages: 54 pages (typical published edition).

Scope

The standard applies to three‑phase and single‑phase a.c. electrical equipment operating at 50 Hz with nominal voltages from 1 kV to 750 kV. Typical covered items include power and instrument transformers, reactors, circuit‑breaking and switching apparatus, insulators, full or partial‑insulation gas‑insulated switchgear, current- and voltage‑transformers, bushings and complete distribution assemblies. Climatic categories and placement categories are referenced in accordance with GOST 15150.

Key topics and requirements

• Definitions and classification of insulation and insulation coordination for AC equipment in the 1–750 kV range.
• Required dielectric strength levels and specified test voltages for power‑frequency and impulse tests.
• Test procedures and acceptance criteria for routine, type and sample testing of insulation.
• Requirements for application to different equipment types (transformers, reactors, switchgear, insulators, bushings, capacitors, etc.).
• Consideration of climatic and placement categories (per GOST 15150) when selecting test levels and procedures.

Typical use and users

Manufacturers of power transformers, reactors, switchgear and insulators; utilities and transmission/distribution companies; type‑test and certification laboratories; design engineers responsible for insulation coordination; regulatory and conformity assessment bodies in CIS/EASC member countries. The standard is used to define test regimes for product development, type approval and factory acceptance testing.

Related standards

Q: Who typically uses it?

A: Equipment manufacturers, utilities, test laboratories, certifying bodies and design engineers working on high‑voltage AC equipment in jurisdictions that apply GOST/EASC standards.

Q: Is it current or superseded?

A: GOST 1516.3-96 is an adopted interstate standard (designation year 1996) and was introduced into national use (as a Russian state standard) from 1 January 1999; it is listed as active/acting in multiple national catalogs with no widely published amendments noted in those catalogs.
