Harmonics & Flicker

Applicable Test Standards

International Electrotechnical Committee (IEC)

IEC/EN 61000-3-2 controls the level of distortion of the current drawn by all equipment rated up to 16 amps

IEC/EN 61000-3-3 controls the level of voltages changes that equipment rated up to 16 amps will impose on the ac supply

The Harmonics and Flicker standards require fast and accurate analysis of electrical power quantities:

Continuous harmonics

• 400+ measurements every 200ms.
• Discrete Fourier Transform for a reference instrument

Continuous voltage changes

• every 10ms (1/2 cycle@50 Hz)
• real-time flickermeter processing

Limit checking and reports

• Calculation of harmonic limits from averaged and maximum readings
• Comparison to different class limits
• Recording and presentation of results
