The Fluke 1748 Three-Phase Power Quality Logger delivers simultaneous measurement and logging of over 500 power quality parameters across three-phase industrial and commercial electrical systems. Built to IEC 61000-4-30 Class A Edition 3 standards, it captures voltage and current harmonics, interharmonics, flicker, rapid voltage changes, neutral current, and unbalance data with Class A accuracy. The instrument records dips, swells, interruptions, and event waveforms with full RMS profiles and severity timestamps across multiple logging sessions, enabling root-cause analysis of power distribution disturbances.
