GOST 30804.3.3-2013 PDF

Full title and description

GOST 30804.3.3-2013 — Electromagnetic compatibility (EMC) of technical equipment. Limits — Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for equipment with rated current ≤ 16 A per phase (not subject to conditional connection). The standard specifies limits and test/measurement methods for assessing voltage changes, fluctuations and flicker caused by equipment connected to general-purpose low-voltage supply systems.

Abstract

This standard sets normative limits and test procedures for voltage changes, voltage fluctuations and flicker produced by electrical, electronic and radio‑electronic equipment intended to be connected to public low‑voltage distribution systems (phase‑to‑neutral nominal voltage ≈ 220 V, 50 Hz) where equipment has a rated input current not exceeding 16 A per phase. It provides methods of measurement and evaluation for type testing of devices that may affect power quality by producing rapid voltage changes or flicker.

Scope

The standard applies to electrical, electronic and radio‑electronic equipment with rated current ≤ 16 A per phase, intended for connection to public low‑voltage distribution systems (nominal phase‑to‑neutral 220 V at 50 Hz) and not subject to conditional connection. It establishes normative limits for sudden voltage changes, steady voltage fluctuations and flicker that equipment may impose on the supply network under specified test conditions, and it gives guidance on methods for measurement and assessment of those effects.

Key topics and requirements

• Definition of limits for voltage changes (temporary voltage dips/interruptions and step changes) and short‑term voltage fluctuations caused by equipment during normal operation.
• Limits and assessment methods for flicker (perceptible light modulation caused by voltage fluctuations) produced by equipment under test.
• Applicability restricted to equipment with rated current ≤ 16 A per phase (type‑test regime, not conditional connection devices).
• Specified test circuits, measurement points, test procedures and evaluation metrics for repeatable laboratory testing.
• Normative alignment with IEC 61000‑3‑3 (requirements and methods derived from the IEC document).

Typical use and users

Used by product designers, electrical/electronic manufacturers, EMC test laboratories, certification bodies, utilities and compliance engineers to verify that equipment does not exceed permissible voltage‑change or flicker impacts on public low‑voltage networks. Also used by standards and regulatory specialists when drafting technical specifications or conformity assessment documentation.

Related standards
