Overview
IEC 61000-4-15:1997/AMD1:2003 is an amendment to the international standard focusing on Electromagnetic Compatibility (EMC). Specifically, it updates Part 4-15, which addresses testing and measurement techniques related to flickermeters - devices designed to measure voltage fluctuations that cause flicker in lighting systems. This amendment refines the functional and design specifications of the flickermeter to enhance measurement accuracy and compatibility with different electrical systems.
Developed by IEC Technical Committee 77A on low-frequency phenomena, this amendment aligns with prior work from international groups such as the International Union for Electroheat (UIE) and the IEEE. While the specifications focus on common power network standards at 230 V/50 Hz and 120 V/60 Hz, it also notes ongoing considerations for other voltage and frequency levels.
Key Topics
Flickermeter Design and Functionality
The amendment updates the flickermeter’s functional diagram and key operational blocks, including the voltage adaptor, weighting filters, squaring and smoothing circuits, and classifiers. These components simulate the combined response of gas-filled lamps and the human eye to voltage fluctuations, ensuring perceptible flicker is accurately assessed.Voltage Fluctuation Responses
Detailed tables provide normalized flickermeter response values for sinusoidal and rectangular voltage fluctuations. These values represent the relative input voltage change (ΔV/V) that corresponds to one unit of perceptibility in flicker output, enhancing standardized assessment for various flicker patterns.Input Voltage Ranges and Calibration
The document clarifies acceptable ranges for rated input voltages with defined upper and lower limits, essential for consistent calibration across different electrical environments. Additionally, it specifies the operation of internal calibration generators modulated at precise frequencies based on the supply frequency.Weighting Filter Specifications
Weighting filters are critical for excluding unwanted signal components. The amendment specifies the use of Butterworth filters of the 6th order with exact cut-off frequencies (35 Hz for 230 V/50 Hz systems and 42 Hz for 120 V/60 Hz systems), providing definitive guidance for flickermeter design and the possibility of future digital filter implementations.Performance Testing and Classification
The amendment revises testing criteria for flickermeter classification, including detailed test specifications based on the frequency and magnitude of rectangular voltage variations. These tests ensure flickermeters meet EMC requirements and maintain sensitivity across typical electrical disturbances.
Applications
Power Quality Monitoring
The updated IEC flickermeter standard is widely applied in power quality assessment, allowing utility companies and electrical engineers to monitor voltage fluctuations that cause flickering in lighting systems. Compliance ensures consistent evaluation of flicker impact on end-user environments.Electromagnetic Compatibility Testing
Manufacturers of electrical and electronic equipment utilize this standard to design products that minimize voltage fluctuation emissions. Flickermeter measurements assist in certifying equipment against EMC regulations, reducing the risk of causing harmful flicker.Lighting System Design and Evaluation
The standard provides manufacturers of lamps and lighting control devices with a reference for flicker sensitivity and response, enabling improved design and testing to ensure user comfort and compliance with flicker limits.Regulatory Compliance and Certification
Regulatory agencies reference IEC 61000-4-15 in setting national and international EMC standards, making its amendment critical for ongoing compliance and standardization of flickermeter testing methodologies.

1 Scope and object
Replace the second paragraph by the following:
This section is based partly on work by the “Disturbances” Working Group of the International
Union for Electroheat (UIE), partly on work of the IEEE, and partly on work within IEC itself.
The flickermeter specifications in this section relate only to measurements of 230 V, 50 Hz
inputs and 120 V, 60 Hz inputs; specifications for other voltages and other frequencies are
under consideration.
