Effective Date

Overview

IEC 61000-4-13:2002/AMD2:2015 is an important amendment to the international standard addressing Electromagnetic Compatibility (EMC), specifically focused on testing and measurement techniques related to harmonics and interharmonics, including mains signalling at AC power ports. This amendment, published by the International Electrotechnical Commission (IEC), updates the low frequency immunity test procedures and frequency ranges critical for evaluating the impact of electrical disturbances on equipment performance in power systems.

The amendment refines existing parameters, such as shifting the mains signalling frequency range from "110 Hz to 3 kHz" to "100 Hz to 3 kHz" and updating testing methodologies with the introduction of the Meister curve, a benchmark for ripple control systems in public networks. It serves as a fundamental resource for ensuring electromagnetic compatibility in electrical and electronic devices connected to AC mains, focusing on immunity to harmonics, interharmonics, and ripple control signaling.

Key Topics

  • Harmonics and Interharmonics Testing
    The amendment addresses low-frequency immunity testing against both harmonics (integer multiples of the fundamental frequency) and interharmonics (non-integer multiples), which can cause functional disturbances in electrical equipment.

  • Mains Signalling (Ripple Control)
    Updated frequency range specifications to 100 Hz - 3 kHz for ripple control signals transmitted on the power network. Ripple control signals are crucial for remote control and management of electrical loads.

  • Meister Curve Application
    Introduces the Meister curve as a reference for immunity levels when testing ripple control systems. The curve defines allowable test levels across frequencies from 100 Hz up to 3 kHz, detailing immunity requirements for various equipment classes.

  • Test Levels and Frequency Steps
    The amendment revises the test levels defined for interharmonics and the application of the Meister curve for different equipment classes (Class 1, 2, 3, and X). These test levels dictate the percentage of nominal voltage (U1) used during testing over specified frequency ranges.

  • Test Procedures and Flowcharts
    Provides detailed test flowcharts for Classes 1 and 2, outlining the step-by-step testing sequence for harmonic combinations, individual harmonics/interharmonics, and the Meister curve sweep, ensuring systematic immunity evaluation.

Applications

  • Power Supply and Grid Equipment Testing
    Ensures power generation, transmission, and distribution equipment can withstand harmonics and ripple signals without malfunction.

  • Consumer and Industrial Electronics Certification
    Validates the immunity of appliances and industrial devices connected to the AC mains against interharmonics and mains signaling disturbances.

  • EMC Testing Laboratories
    Provides a standardized test method for labs performing compliance testing of electrical equipment under low frequency EMC conditions.

  • Grid Signalling and Control Systems
    Supports the reliable performance of remote control systems that use ripple control signaling on the public power network.

  • Product Development and Quality Assurance
    Assists manufacturers in designing products resilient to electromagnetic interference caused by harmonics and interharmonics, enhancing product reliability and safety.

Related Standards

  • IEC 61000-2-2:2007 – Provides the Meister curve referenced in this amendment for ripple control immunity levels.

  • IEC 61000-4-7 – Addresses general testing methods for harmonics and interharmonics.

  • IEC 61000-4-11 – Details immunity testing for voltage dips, short interruptions, and voltage variations.

  • IEC 61000-3 Series – Covers emission limits for harmonics and interharmonics in power distribution networks.

Summary

IEC 61000-4-13:2002/AMD2:2015 amendment plays a critical role in harmonizing international testing practices for electromagnetic immunity against low-frequency harmonics, interharmonics, and mains signaling. Enhanced by the introduction of the Meister curve and updated frequency ranges, it ensures equipment connected to AC supply networks maintain optimal functionality and reliability under electromagnetic disturbances. Its practical application spans across power utilities, manufacturers, testing labs, and regulatory bodies to uphold EMC standards essential for stable, interference-free electrical systems.
