Description
Three power quality modes are packed with features The three power quality waveform modes in the 5520A-PQ include Composite Harmonic, Flicker Simulation, and Sags and Swells Simulation. These waveforms are available in either the single output mode (voltage or current) or dual output modes (voltage + current and voltage + voltage). The modes provide traceability for harmonic analysis, flicker, and sags and swells functions of power quality measurement instruments. The PQ option adds powerful new functionality to the 5520A:
• Fundamental generation combined with up to 15 harmonics, producing a “multi-tone” output to verify the performance of harmonic analyzers.
• Flicker simulation to verify the performance of Flickermeters described in EN 61000-4-15.
• Sags and swells simulation to test power quality analyzers for one of the most critical parameters in an electrical distribution system.
• Improved phase uncertainty over the standard 5520A sinewave modes, for calibrating higher precision wattmeters. As in all 5520As, these functions also address your power calibration requirements:
• Programmable phase angle between the two output channels (dual output modes) with .01 ° resolution.
• Phase locking of multiple 5520As for polyphase power testing.
• Performance verification of both three- and four-wire wattmeters.
• Compensation for inductive loads available in all current output modes.
