1 - Introduction The Agilent 6800-Series AC Power Source/Analyzers The Agilent 6800-Series AC Power Source/Analyzers are specifically designed for testing products compliant to the IEC low-frequency emissions regulations for quasi-stationary current harmonics, fluctuating current harmonics, and voltage fluctuations and flicker. The following models provide up to full power coverage of the single-phase regulatory requirements: Model rms Voltage rms Current peak Current VA 230 Vrms (compliance) 3.

Introduction - 1 EN 61000-3-2 and EN 60555 Part 2 Regulations EN 61000-3-2 and EN 60555 Part 2 regulate the magnitude of harmonic currents drawn by products from the ac line. For example, harmonic currents can occur as a result of high peak currents drawn by switch-mode power supplies. Power companies, particularly in Europe, have led a regulatory initiative to limit harmonic current generation at the product level because of a variety of undesirable effects on the mains environment such as: in

1 - Introduction EN 61000-3-3 Regulation EN 61000-3-3 regulates the magnitude, rate, and time-duration of voltage fluctuations and flicker caused by products connected to the ac line. Voltage fluctuations are created by time-varying current drains working against branch circuit impedance that exists in all power distribution networks. Flicker occurs when an incandescent lamp changes in intensity due to the frequency and amplitude of voltage fluctuations in the same branch circuit. Because flicke
